What is the name of the os x built-in backup utility and what does it do?
The backup utility that comes with Mac OS X 10.6 Snow Leopard is named “Time Machine,” and it does two things: it archives and restores data on your computer. It’s a powerful and flexible tool that can help protect your files from damage and viruses, but in order to get the most out of it, you need to know how to use the features it features. In this article I will go over operating Time Machine’s backup setting options in order to use these tools effectively.

A few facts about Time Machine : it can be set up to backup the user’s entire system drive, the user’s selected folder, the user’s Home folder, individual Mac file and folder that have been given a name you choose and OS X defaults for your user account.
Setting up Time Machine : When you first turn on Time Machine, you are given a screen that displays the following options: “Choose a Backup Disk,” “Choose a Backup Location,” and “Specify Backup Options.”
How can you use Time Machine to back up your computer files and data?
a. Protecting Files in a Specific Folder: To protect a specific folder, such as the Documents folder, on your Mac – hold down the Option key while clicking the folder you want to protect. If a file or folder is inside of a protected folder, it will be hidden from view.
b. Saving Files and Folders Regularly: It is recommended that you back up your important documents every week or so to ensure you do not lose any data in the event of some kind of hardware failure like your hard drive crashing. This can easily be done with Time Machine by selecting the option “Back Up Now” during the initial setup process for Time Machine on your Mac computer.
c. Other Ways to Back Up Files: Another option is to use an external hard drive to save files on.
d. Restoring Files and Folders: If you need to restore files or folders that were previously backed up, you can do so by following these steps.
What are some things you should keep in mind when using Time Machine to back up your computer files and data?
a. Fragmented Backups: Because Time Machine creates multiple backups of files, it may be possible to lose data if your hard drive is damaged. For example, if you accidentally delete a file while Time Machine is backing up your files and you later restore the file from an older backup, the original file may not be restored. As a precaution against this, you may want to keep a separate backup of your files (such as on an external hard drive) that’s not part of the Time Machine backup.
b. Restrict Access to Time Machine: If another user has access to your computer, you are potentially putting all of your data at risk by using Time Machine. To protect against this, you can turn off or restrict access to Time Machine by following these steps:
1) Open Finder.
2) Choose Go > Applications.
3) In the list of applications in Finder, select the Time Machine icon.
4) Choose Go > System Preferences.
5) Select the Security tab and click Access on the left side of the window.
How can you restore files or data that have been backed up with Time Machine?
a. Restoring Backups: To restore files that have been backed up with Time Machine, double-click the Time Machine icon (located in the /System/Library/CoreServices folder) or select “Restore From Backup” from the Time Machine menu (located in the /Applications folder). Then choose the backup that you want to restore from.
1. The backup database (also called the “backup catalog”) that provides information about all Time Machine backups for a particular computer is located at ~/Library/Application Support/Time Machine/Backups/. You can restore a single backup from this database or you can restore multiple backups (for example, for each of the laptops in your laptop bag of backup devices).
2. If your backup disk is not connected, then you can connect the disk, select “Restore From Backup” from the Time Machine menu in the /Applications folder, and then open the Time Machine Preferences pane. In the onetime restore area, click “Restore All Backups,” click “Continue,” and then click “OK.”
3. If you have saved and restored several full backups, you may wish to use the Select Backup window (Figure 4) to choose the backup that you want to restore.
