Performing snapshot rollback
The following procedure requires root access (UNIX) or Administrator privilege (Windows).
To perform snapshot rollback (UNIX)
- Start the Backup, Archive, and Restore interface.
/usr/openv/netbackup/bin/jbpSA &
- Click the Restore Files tab.
- Click Actions > Specify NetBackup Machines to specify the server, source client, policy type, and destination client.
- For the Restore Type, select Point in Time Rollback.
The Browse directory field is grayed out, with root (/) as default.
Instant Recovery backups are displayed in the Backup History window, for all dates (you cannot set a range).
- Select an image from the list and click OK.
The image contents are displayed in the Directory Structure pane of the Restore Files tab.
You can select root level or mount points (file systems or volumes), but not folders or files at a lower level.
- In the Directory Structure list, click the check box next to the root node or a mount point beneath root.
You can select a file system or volume, but not lower-level components.
- Click the Restore option.
The only available destination option is Restore everything to its original location.
- For file systems, you can choose to skip file verification by placing a check in the Skip verification and force rollback option.
Warning:
Click Skip verification and force rollback only if you are sure that you want to replace all the files in the original location with the snapshot. Rollback deletes all files that were created after the creation-date of the snapshot that you restore.
If Skip verification and force rollback is not selected, NetBackup performs checks on the file system.
See Notes on rollback.
If the checks do not pass, the rollback aborts and the Task Progress tab states that rollback could not be performed because file verification failed.
The rest of the procedure is identical to a normal restore as explained in the NetBackup Backup, Archive, and Restore Getting Started Guide and help.
