Q: Can I restart a TSM restore that was interrupted by a power outage or network failure?

Answer

Yes, some TSM restores are restartable. If the restore process stops because of a power outage or network failure and the session is not re-established within five minutes, the server records the point at which this occurred. This record is known to the TSM client as a restartable restore. It is possible to have more than one restartable restore session.

To find out if the TSM client has any restartable restore sessions, do one of the following:

• In the GUI: Go to the Actions menu and select Restartable Restores.
• On the command line: Use the Query Restore command.

You must complete a restartable restore before attempting further backups of the file system. If you attempt to repeat the restore that was interrupted or try to back up the destination file space, the attempt will fail because you did not complete the original restore.

You can restart the restore at the point of interruption by doing one of the following:

• In the GUI: Select the Restartable restore, and click on Restart.
• On the command line: Enter the Restart Restore command.

Or, you can delete the restartable restore by doing one of the following:

• In the GUI: Select the Restartable Restore and click on delete.
• On the command line: Use the Cancel Restore command.

If you restart the interrupted restore, it will restart with the first transaction, which may consist of one or more files, not completely restored when the interruption occurred. Because of this, you may receive some replace prompts for files from the interrupted transaction which were already restored.
