You'd have to change the LastWritten column in the catalog.

If you want to make sure certain volumes are not recycled, use the console command 'update' to disable recycling or set the retention time. A retention time of 0 zero means automatic pruning is disabled. Keep in mind that the job retention time still applies, but Bacula will not overwrite your volumes.
