Example of true image restores
The following table lists the files that were backed up in the /home/abc/doc/ directory of a UNIX client during a series of backups between 12/01/2015 and 12/04/2015. was enabled for the policy that performed the backups.
Table: Sample backups taken before a true image restore
Day | Type of backup | Files that are backed up in /home/abc/doc |
---|---|---|
12/01/2015 | Full | file1 file2 dirA/fileA dirB/fileB file3 |
12/02/2015 | Incremental | file1 file2 dirA/fileA ---------- ----- |
12/03/2015 | Incremental | file1 file2 dirA/fileA ---------- ----- |
12/04/2015 | User backup | file1 file2 dirA/fileA ---------- ----- dirC/fileC file4 |
12/04/2015 | Incremental | file1 file2 ---------- ---------- ----- ---------- file4 |
Note:
Dashes ( ------ ) indicate that the file was deleted before this backup.
A restore of the 12/04/2015 version of the /home/abc/doc/ directory produces following results:
After a regular restore | The restored directory contains all files and directories that ever existed in /home/abc/doc/ from 12/01/2015 (last full backup) through 12/04/2015: file1 file2 dirA/fileA dirB/fileB file3 dirC/fileC file4 |
After a true image restore | The restored directory contains only the files and directories that existed at the time of the incremental backup: file1 file2 file4 NetBackup does not restore any of the files that were deleted before the 12/04/2015 incremental backup. The restored directory does not include the subdirectories dirA and dirC, even though they were backed up on 12/04/2015 with a user backup. NetBackup did not restore these directories because they did not exist at the time of the incremental backup. The incremental backup was the reference for the true image restore. |
Consider the following points to use either
or :NetBackup collects additional information for the incremental backups that collect true image restore information. Policies that use move detection require even more space.
Incremental backups are slower for a policy in which true image restore information is collected.
Configure the period of time that NetBackup retains the true image restore information. Set the Clean-up properties dialog box.
property in theSee Clean-up properties.
Only directories can be listed and selected. In true image restore mode, the client interface does not display individual files. Refer to the online Help in the
client interface for more information on true image restores.A true image restore preserves the files that are currently in the directory but were not present when the backup was completed. If you created a file file5 after an incremental backup on 12/04/2015 but before a restore, the contents of the restored directory would be as follows:
file1 file2 file4 file5
