INTRODUCTION
Time Machine is a backup utility developed by Apple. It is included with Mac OS X and was introduced with the 10.5 "Leopard" release of Mac OS X. The software is designed to work with the Time Capsule as well as a number of external FireWire (IEEE 1394a/b) and USB hard drives.
Time Machine, like many backup utilities, creates incremental backups of files that can be restored at a later date. It allows the user to restore the whole system, multiple files, or a single file. It works within iWork, iLife, and several other compatible programs, making it possible to restore individual objects (e.g.: photos, contacts, calendar events) without leaving the application. According to Apple support personnel
"Time Machine is a backup utility, not an archival utility, it is not intended as offline storage. Time Machine captures the most recent state of your data on your disk. As snapshots age, they are prioritized progressively lower compared to your more recent ones."
For backups to a network drive, Time Machine allows the user to back up Apple Macintosh computers through Apple's AirPort networking, and supports backing up to normal network attached storage devices or servers without the use of hand-tuned configuration options, accessed through the Terminal. Apple's Time Capsule acts as a network storage device specifically for Time Machine backups, allowing both wired and wireless backups to the Time Capsule's internal 500GB, 1TB or 2TB hard disk.
MAC OS X
Mac OS X is the world’s most advanced operating system. Built on a rock-solid UNIX foundation and designed to be simple and intuitive, it’s what makes the Mac innovative, highly secure, compatible, and easy to use. Quite simply, there is nothing else like it.
Power of UNIX. Simplicity of the Mac.
Mac OS X is both easy to use and incredibly powerful. Everything from the desktop you see when you start up your Mac to the applications you use every day is designed with simplicity and elegance in mind. So whether you’re browsing the web, checking your email, or video chatting with a friend on another continent, getting things done is at once easy to learn, simple to perform, and fun to do. Of course, making amazing things simple takes seriously advanced technologies, and Mac OS X is loaded with them. Not only is it built on a rock-solid, time-tested UNIX foundation that provides unparalleled stability, it also delivers incredible performance, stunning graphics, and industry-leading support for Internet standards.
Perfect integration of hardware and software.
Since the software on every Mac is created by the same company that makes the Mac itself, you get an integrated system in which everything works together perfectly. The advanced technologies in the operating system take full advantage of the 64-bit, multicore processors and GPUs to deliver the greatest possible performance. The built-in iSight camera works seamlessly with the iChat software so you can start a video chat with a click. Your Mac notebook includes a Multi-Touch trackpad that supports pinching, swiping, and other gestures. And the OS communicates with the hardware to deliver incredible battery life by spinning down the hard drive when it’s inactive, by intelligently deciding whether the CPU or GPU is best for a task, and by automatically dimming the screen in low-light conditions.
Elegant interface and stunning graphics.
The most striking feature of a Mac is its elegant user interface, made possible by graphics technologies that are built to leverage the advanced graphics processor in your Mac. These technologies provide the power for things like multiway chatting, real-time reflections, and smooth animations. Fonts on the screen look beautiful and extremely readable. A soft drop shadow makes it clear at a glance which window is active and which ones are in the background. You can preview just about any type of file using Quick Look, and because the previews are high resolution, you can actually read the text. Built-in support for the PDF format means you can view or create PDFs from almost any application in the system.
Highly secure by design.
Mac OS X doesn’t get PC viruses. And with virtually no effort on your part, Mac OS X protects itself from other malicious applications. It was built for the Internet in the Internet age, offering a variety of sophisticated technologies that help keep you safe from online threats. Because every Mac ships with a secure configuration, you don’t have to worry about understanding complex settings. Even better, it won’t slow you down with constant security alerts and sweeps. And Apple responds quickly to online threats and automatically delivers security updates directly to your Mac.
Built for compatibility.
The versatility and power of Mac OS X make it compatible in almost any environment, including Windows networks. It works with virtually all of today’s digital cameras, printers, and other peripherals without the need to manually download separate drivers. It opens popular file types such as JPG, MP3, and Microsoft Word, Excel, and PowerPoint documents. In addition, Mac OS X includes built-in support for the industry-standard PDF format, so you can read and create PDFs from almost any application in the system — perfect for sharing work with colleagues whether they use a Mac or a PC. If you want to run Windows on your Mac, you can do that, too. And Mac OS X Snow Leopard is the only operating system with built-in support for the latest version of Microsoft Exchange Server, so you can use your Mac at home and at work and have all your messages, meetings, and contacts in one place.
Innovation for everyone.
Mac OS X comes standard with a wide range of assistive technologies that help people with disabilities experience what the Mac has to offer — including many features you won’t find in other operating systems at any price. For example, the built-in VoiceOver screen-reading technology makes it possible for those who are blind or have low vision to control their computer using key commands or gestures on a Multi-Touch trackpad. Mac OS X also offers out-of-the-box support for over 40 braille displays, including Bluetooth displays, and many other accessibility features, such as dynamic full-screen magnification, playback of closed captions, and a scalable screen.
Reliable to the core.
The core of Mac OS X is built on the same ultrareliable UNIX foundation that powers industrial-strength servers, helping to ensure that your computing experience remains free from system crashes and compromised performance. Even upgrading your Mac to the next version of Mac OS X is reliable and easy. It checks your applications to make sure they’re compatible and sets aside any programs known to be incompatible. If a power outage interrupts your installation, it can start again without losing any data. Best of all, upgrading doesn’t require reformatting your drive; you can keep all your compatible applications, files, and settings. And if something goes wrong when you’re using your Mac, Time Machine is there to keep automatic backups of everything on your drive.
Fully featured, fully loaded.
Mac OS X comes in a single, full-featured version that includes a large collection of beautifully designed applications. They not only let you surf the web, conduct video and text chats, manage your contacts, and accomplish other day-to-day tasks — they also work together to make you more productive and let you have more fun.
MAC OS X SNOW LEOPARD
Refined, not reinvented.
Mac OS X is renowned for its simplicity, its reliability, and its ease of use. So when it came to designing Snow Leopard, Apple engineers had a single goal: to make a great thing even better. They searched for areas to refine, further simplify, and speed up — from little things like ejecting external drives to big things like installing the OS. In many cases, they elevated great to amazing. Here are just a few examples of how your Mac experience was fine-tuned.
A more advanced, more nimble Finder.
The Finder has been completely rewritten in Cocoa to take advantage of all the modern technologies in Mac OS X, including 64-bit support and Grand Central Dispatch. It’s more responsive from top to bottom, with snappier performance throughout the Finder. And it includes new features such as customizable Spotlight search options and an enhanced icon view that lets you thumb through a multipage document or watch a QuickTime movie.
New look, new features for Exposé and Stacks.
Exposé is refined and more convenient. It’s now integrated in the Dock, so you can just click and hold an application icon in the Dock and all the windows for that application will unshuffle so you can quickly change to another one. Exposé also has a whole new look. Windows are displayed in an organized grid, making it even easier to find what you’re looking for. And stacks — Dock items that give you fast access to a folder of files — are now scrollable, so you can easily view all items. You can also navigate through folders in a stack to see all the files inside it.
Quicker Time Machine backup.
Introduced in Mac OS X Leopard, the revolutionary Time Machine made backing up your hard drive easy for the first time. Time Capsule took backup even further with its wireless hard drive that works seamlessly with Time Machine. Now Snow Leopard makes Time Machine up to 80 percent faster and reduces the time it takes to complete your initial backup to Time Capsule.
Faster to wake up and shut down.
With Snow Leopard, your Mac wakes from sleep up to twice as quickly when you have screen locking enabled. And shutting down is up to 80 percent faster, saving precious moments when you’re trying to head home or to the airport.1
Faster at common tasks.
- Wake up 2x
- Shut down 1.8x
Times faster than Leopard.¹
Faster, more reliable installation.
Upgrading your Mac has never been easier. For Snow Leopard, the entire process has been simplified, streamlined, and is up to 50 percent faster, yet more comprehensive and reliable.2 For example, Snow Leopard checks your applications to make sure they’re compatible and sets aside any programs known to be incompatible. In case a power outage interrupts your installation, it can start again without losing any data.
The right service at the right time.
The Services menu in Mac OS X lets you use features of one application while working in another. In Snow Leopard, services are more simplified, streamlined, and helpful. The Services menu is contextual, so it shows just the services appropriate for the application you’re using or content you’re viewing rather than all available services. You can access services with a right click of your mouse or Control-click of your trackpad. You can configure the menu to show only the services you want, and you can even create your own services using Automator.
Automatic updates for printer drivers.
Snow Leopard makes sure you always have the most up-to-date driver so you can get the most from your printer. When you plug in a printer, Mac OS X can download the latest driver available over the Internet. And it periodically checks to make sure it has the latest driver. If not, it downloads the newest version through Software Update. Easy.
The 64-bit transition.
The entire computing industry is moving from 32-bit to 64-bit technology, and it’s easy to see why. Today’s Mac computers can hold up to 32GB of physical memory, but the 32-bit applications that run on them can address only 4GB of RAM at a time. 64-bit computing shatters that barrier by enabling applications to address a theoretical 16 billion gigabytes of memory, or 16 exabytes. It can also enable computers to crunch twice the data per clock cycle, which can dramatically speed up numeric calculations and other tasks. Earlier versions of Mac OS X have offered a range of 64-bit capabilities. Now Snow Leopard takes the next step in the transition from 32-bit to 64-bit.
Built-in applications are now 64-bit.
Nearly all system applications — including the Finder, Mail, Safari, iCal, and iChat — are now built with 64-bit code. So not only are they able to take full advantage of all the memory in your Mac, but the move to 64-bit applications also boosts overall performance. Together with other refinements and improvements in Snow Leopard, this means that just about everything you do — from launching applications like QuickTime to running JavaScript in Safari to opening image files — will feel faster and more responsive.
Ready for the future.
The 64-bit support in Snow Leopard makes Mac OS X completely ready for whatever computing enhancements might arrive in the future. For example, Snow Leopard is ready to support up to 16 terabytes of RAM — about 500 times more than today’s Mac computers can accommodate. That may sound like more RAM than you’ll ever need, but who can predict the requirements of high-performance computers in the future? Mac OS X Snow Leopard comes prepared for anything.
More secure than ever.
Another benefit of the 64-bit applications in Snow Leopard is that they’re even more secure from hackers and malware than the 32-bit versions. That's because 64-bit applications can use more advanced security techniques to fend off malicious code. First, 64-bit applications can keep their data out of harm's way thanks to a more secure function argument-passing mechanism and the use of hardware-based execute disable for heap memory. In addition, memory on the system heap is marked using strengthened checksums, helping to prevent attacks that rely on corrupting memory64-bit applications in Snow Leopard deliver faster performance at common operations.
32-bit compatible.
To ensure simplicity and flexibility, Mac OS X still comes in one version that runs both 64-bit and 32-bit applications. So you don’t need to update everything on your system just to run a single 64-bit program. And new 64-bit applications work just fine with your existing storage devices, PCI cards, and Snow Leopard-compatible printers.
BACKUP TOOLS
Backup software are computer programs used to perform backup; they create supplementary exact copies of files, databases or entire computers. These programs may later use the supplementary copies to restore the original contents in the event of data loss.
Key features
There are several features of backup software that make it more effective in backing up data.
Volumes
Voluming allows the ability to compress and split backup data into separate parts for storage on smaller, removable media such as CDs. It was often used because CDs were easy to transport off-site and inexpensive compared to hard drives or servers.
However, the recent increase in hard drive capacity and decrease in drive cost has made voluming a far less popular solution. The introduction of small, portable, durable USB drives, and the increase in broadband capacity has provided easier and more secure methods of transporting backup data off-site.
Data compression
Since hard drive space has cost, compressing the data will reduce the size allowing for less drive space to be used to save money.
Remote backup
Several factors have contributed to a surge in the use of remote or offsite backup of data to geographically distant sites.
- The rapid growth of data and its importance to business.
- The rapid adoption of high-speed broadband internet.
- The falling price of disk drive technology.
- The rise of risks such as hackers, natural disasters, fires, damage by power outages, malware attacks, terrorist attacks, hardware failure.
These structural changes present opportunities for young startups, which are serving this growing market with next-generation backup technologies that automatically back up data to offsite data centers (sometimes called vaults) via the Internet. Many banks, stock exchanges, and other large institutions often do this to ensure data integrity.
Access to open files
Many backup solutions offer a plug-in for access to exclusive, in use, and locked files.
Incremental backups
Backup solutions generally support incremental backups in addition to full backups, so only material that is newer or changed compared to the backed up data is actually backed up, in order to dramatically increase the speed of the backup process.
Schedules
Backup schedules are usually supported to reduce maintenance of the backup tool and increase the reliability of the backups.
Encryption
To prevent data theft, some backup software offers cryptography features to protect the backup.
Transaction mechanism
To prevent loss of previously backed up data during a backup, some backup software (e.g. Areca Backup) offer Transaction mechanism (with commit / rollback management) for all critical processes (such as backups or merges) to guarantee the backups' integrity.
TIME MACHINE
Never again worry about losing your digital files. Time Machine automatically saves up-to-date copies of everything on your Mac — photos, music, videos, documents, applications, and settings. If you ever have the need, you can easily go back in time to recover anything
Set it, then forget it.
Time Machine works with your Mac and an external hard drive. Just connect the drive and assign it to Time Machine and you’re a step closer to enjoying peace of mind. Time Machine will automatically back up your entire Mac, including system files, applications, accounts, preferences, music, photos, movies, and documents. But what makes Time Machine different from other backup applications is that it not only keeps a spare copy of every file, it remembers how your system looked on a given day — so you can revisit your Mac as it appeared in the past.
Go back in time.
Say you accidentally deleted a file you meant to save. Simply enter the Time Machine browser and you’ll see exactly how your computer looked on the dates you’re browsing. You can browse for files using Cover Flow, or you can perform a Spotlight search to find what you need across all your backups. Use the timeline to select a specific date, or let Time Machine fly through time to find your most recent changes. Before recovering a file, use Quick Look to verify the contents of the file, then click Restore to bring it back to the present.
Every change, every hour.
Following the initial backup of your entire Mac, Time Machine automatically makes incremental backups every hour, every day, copying just the files that have changed since your last backup. And it does this all in the background, so you can continue working while Time Machine is busy copying your files. Time Machine saves the hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for everything older than a month.
Ready when you are.
When your mobile Mac is connected to your backup drive, Time Machine works as you’d expect. When it isn’t connected, Time Machine also works as you’d expect. It keeps track of which files have changed since the last backup and backs them up to your backup drive the next time you connect. On any Mac, if Time Machine is unable to perform a backup, that’s duly noted in its preference pane.
Migration with style.
If you’re setting up a new Mac with files from an old Mac, Time Machine can help simplify the process. Just use Migration Assistant to copy portions of any Time Machine backup to a new Mac, or select “Restore System from Time Machine” in the Utilities menu on your Mac OS X install disc. Choose any date recorded in Time Machine to set up your new Mac exactly as your previous Mac was on that date.
TIME CAPSULE
Want to make your backups even more effortless? Use Time Capsule, Apple’s wireless hard drive and 802.11n base station.
Backing up is something we all know we should do, but often don’t. And while disaster is a great motivator, now it doesn’t have to be. Because with Time Capsule, the nagging need to back up has been replaced by automatic, constant protection. And even better, it all happens wirelessly, saving everything important, including your sanity.
Even faster Time Machine backup.
Time Capsule includes a wireless 1TB or 2TB hard drive1 designed to work with Time Machine in Mac OS X Leopard and Snow Leopard. Just set Time Capsule as the designated backup drive for Time Machine, and that’s it. Depending on how much data you have, your initial backup with Time Capsule could take overnight or longer. After it completes, only changed files are backed up — automatically, wirelessly, and in the background. So you never have to worry about backing up again. Even better, new technologies in Time Capsule and refinements to Time Machine make backing up to Time Capsule using Snow Leopard up to 60 percent faster than before
Backup for everyone.
Have multiple Mac computers in your house? Time Capsule can back up and store files for each Leopard- and Snow Leopard-based Mac on your wireless network. No longer do you have to attach an external drive to each Mac every time you want to back up. Time Capsule spares you the work.
Room for it all.
Time Capsule is your one place for backing up everything. Its massive 1TB or 2TB server-grade hard drive gives you all the capacity and safety you need. So whether you have 250 songs or 250,000 songs to back up, room is the last thing you’ll run out of. And considering all that storage and protection come packaged in a high-speed Wi-Fi base station starting at $299, data isn’t the only thing you’re saving.
TIME CAPSULE WIRELESS
More than just a wireless hard drive, Time Capsule is also a full-featured AirPort Extreme Base Station with 802.11n technology. Experience a high-speed wireless network and a breakthrough way to back up all the Mac computers on your network. All in one device.
Fits your Wi-Fi lifestyle.
You can rest assured that Time Capsule works with other certified 802.11n devices. And it’s compatible with Mac computers and PCs that use 802.11a, b, or g technologies, as well as wireless devices such as iPhone, iPod touch, and Apple TV.
Faster simultaneous dual-band operation.
Some Wi-Fi devices use the 2.4GHz wireless band, including iPhone, iPod touch, and devices using 802.11b/g. Others can use either 2.4GHz or the higher-speed 5GHz band, such as the latest 802.11n-based Mac computers and Apple TV. Instead of choosing one of the bands, Time Capsule operates simultaneously on both bands, and your multiband devices automatically use the best available band. In addition, improvements in antenna design give you up to 50 percent better Wi-Fi performance and up to 25 percent better range than with the previous-generation Time Capsule.
Share the Internet securely with guest networking.
It’s easy to allow guests to use your Internet connection without sharing your password or giving them access to the rest of your network. Simply enable the guest networking feature using the AirPort Utility application and create a separate Wi-Fi network just for your friends. You can set up this guest network with a different password or with none at all. Your primary network — including your printer, attached drives, or other devices — remains secure.
Access your drive over the Internet.
Say you’re traveling and you need a file on your Time Capsule back at home. If you’re a MobileMe member using a Mac with Mac OS X Leopard or Snow Leopard, no problem.2 You can access all the files on your Time Capsule drive over the Internet. Simply register your Time Capsule with your MobileMe account, and its drive appears in the Finder sidebar of your Mac just like any other attached drive. It’s like having your own personal file server wherever you go.
Print command central.
The included USB port is great for sharing a printer throughout your wireless network. Time Capsule and the Bonjour networking technology let everyone in the house or office — Mac and PC users alike — take advantage of one centrally located printer. And if you want to share both a printer and an additional hard drive, you can. Just connect a USB hub to Time Capsule. Whatever the combination, Time Capsule divides and conquers.
Works with Mac and PC.
Time Capsule with Time Machine in Leopard or Snow Leopard is the ideal backup solution. But that doesn’t mean Mac OS X Tiger, Windows XP, and Windows Vista users can’t enjoy the benefits of Time Capsule, too. Because Time Capsule mounts as a wireless hard drive, Tiger and Windows users simply access Time Capsule directly from the wireless network for exchanging and storing files quickly and easily.
WINDOWS SYSTEM RESTORE
Every time you download or install a new game, application, or software update, you make changes to your computer. Sometimes that change may make your system unstable. Have you ever wanted to go back to the way it was? With System Restore, you can.
System Restore works a lot like the Undo command in Microsoft Word. You can use System Restore to remove any system changes that were made since the last time you remember your computer working correctly. System Restore does not affect your personal data files (such as Microsoft Word documents, browsing history, drawings, favorites, or “mail) so you won't lose changes made to these files.
How does System restore work?
Windows XP periodically records a snapshot of your computer. These snapshots are called restore points. Windows XP also creates restore points at the time of significant system events (such as when an application or driver is installed) or you can create and name your own restore points at any time. If you have installed a program that has made your computer unstable, you can open system restore, choose a restore point, and return your computer to its previous stable state.
When you run System Restore, a calendar is displayed to help you find restore points. If you don't use your computer every day, some days might not have any restore points. If you use your computer frequently, you might have restore points almost every day, and some days might have several restore points.
Use System Restore to undo changes you have made to your computer
Before you open the System Restore console, you may want to save your work and close all programs since System Restore requires you to restart your computer.
There are two ways to access System Restore it through Help and Support or through your All Programs folder.
Through Help and Support:
| 1. | Click Start, and then click Help and Support. |
| 2. | Under Pick a Task, click Undo changes to your computer with System Restore. |
| 3. | Follow the instructions on the wizard. |
Through the All Programs menu:
| 1. | Click Start. |
| 2. | Point to All Programs. |
| 3. | Point to Accessories. |
| 4. | Point to System Tools. |
| 5. | Click System Restore. |
| 6. | Follow the instructions on the wizard. |
Creating a restore point can be useful any time you anticipate making changes to your computer that are risky or might make your computer unstable. If something goes wrong, you select the restore point you just created and Windows XP undoes any system changes made since that time.
Create a Restore Point
| 1. | Open System Restore. (See step-by-step instructions above.) |
| 2. | Click Create a restore point, and then click Next. |
| 3. | In the Restore point description box, type a name to identify this restore point as seen in Figure 1 below. System Restore automatically adds the date and time that this Restore Point is created. |
| • | To finish creating this restore point, click Create. |
| • | To cancel restore point creation and return to the Welcome to System Restore screen, click Back. |
| • | To cancel restore point creation and exit the System Restore Wizard, click Cancel. |
To view or to return to this restore point, from the Welcome to System Restore screen of the System Restore Wizard select Restore my computer to an earlier time. Then select the date you created the restore point from the calendar in the Select a Restore Point screen. All of the restore points you created and you computer created on the selected date are listed by name in the list box to the right of the calendar.
Automatic wireless backup
