Apple comes with a program called Time Machine on Mac OS X Leopard operating system for data backup and recovery. Since 70-80% of users do not back up, why should Apple launches the Time Machine in Leopard? Moreover, in the Mac OS X itself has been a lot of backup tools. Here’s what Apple MAC data backup and data recovery methods, and Time Machine (Time Machine) advantage and use. Apple fans before further about the time machine, we might look at Apple’s Mac OS 10.4 comes under some backup tools, as well as their backup method.
Finder’s toolbar has a copy function. By Finder moved to a folder or removable hard disk process shared volumes from the hard disk, who says it is not a backup method. However, this backup significant limitations. First, the Finder with the mouse to the file or folder copied to another disk or path, or some important information is lost or changed, which includes all of the information file or folder, substitute the owner of the information, and so on. Second, even if one can be used for all the files and folders under the boot disk with Finder moved to another disk, still can not get a boot system. Third, Finder itself does not provide timing or automatic replication and other functions. Fourth, as a simple replication process, there is no more advanced mechanisms to improve the speed of copying.
2. Disk Tools
Disk Utility can be used to create the image, this function allows the user to make an image of the entire hard disk to another disk or shared storage volumes in. Image is nothing more than a DMG or sparse-image file or a special package, although the system is paralyzed, you can use Disk Utility in the recovery (Restore) function re-copy the hard drive with the image, but the image itself can not be started directly. In other words, your system will not boot, but you have a DMG image of the original system, you can restore the state to produce an image with the image when the system, but can not allow the system to start immediately, because the recovery itself will take one or two hours or longer.
Of course, the use of disk recovery tool, you can clone the entire disk to a hard drive something completely copied to the hard disk to another. When the system fails, you put clone clone hard drive or hard disk that is connected via FireWire, you can start using the clone, you can use the machine immediately.
However, the various versions of the Mac OS X Disk Utility function under different. Disk Utility can not for the PPC architecture currently running system disk or directly for the production of the entire disk image cloning. You need to use other boot hard disk or CD-ROM to start, and then on the original boot disk for backup, and this often results in the need to store the backup on the third disk. Suppose you use the system installation DVD to start the machine’s built-in hard drive for backup, which backed onto a removable hard disk storage, DVD, built-in and removable hard disk adds up to three discs. Disk Utility for Intel architecture, you must use a system running them do the entire disk cloning. If the system is installed with the DVD launch, DVD inside the Disk Utility does not allow you to select the target or source volume. But that the use of the system running the Disk Utility to clone the entire disk itself, although the result is also able to start the drive, but you will find a backup system hidden files and folders are actually becomes visible, indicating that Intel architecture Disk Utility in replication or omissions. Another disk tool itself does not provide any mechanism for automatic timed backups.
3. Apple Backup
Apple Backup itself is not random, there’s, which itself is a remote backup for .mac users and design, but also allows the user to select other media files for backup storage. Apple Backup with a timer function, the user can set the time automatically backed up. However, Apple Backup can not back up the entire system. In other words, once the hard disk problems, paralyzed the entire system, the user must first restore the system before you can use Apple Backup to restore files.
OK, here is the part one of the data backup and restore data method on your Mac, next time I will show you how time machine works.
