Description |
For Instructions |
---|---|---|
1. Identify the file systems to back up |
Identify which file systems need to be backed up on a daily, weekly, or monthly basis. | |
2. Determine the type of backup |
Determine the type of backup you need for the file systems at your site. | |
3. Create the backup |
Use one of the following methods: |
|
|
If you want to have full and incremental backups of your file systems, use the ufsdump command. | |
|
If you would like to create a snapshot of file system while it is active and mounted, consider using the fssnap command. | |
|
If you just want to have full backups of your personal home directory or smaller, less-important file systems, use the tar, cpio, or pax commands. | |
4. Restore a file system |
(Optional) Select the restoration method that is based on the command used to back up the files or file system. |
|
|
Restore a file system backup that was created with the ufsdump command. | |
|
Restore a file system that was created with the tar, cpio, or pax command. | |
5. Restore the root (/) or /usr file system |
Optional Restoring the root (/) or /usr file system is more complicated than restoring a non-critical file system because you need to boot from a local CD or from the network while these file systems are being restored. |
