Repair, Recovery, and Restore |
Tape media can wear out, become unstable, or become unusable. If this happens, you can make a media copy and recover using the media copy set. This process ensures that the managed data is safe for a longer period of time. If you cannot make a media copy because only one drive is available or no tapes are available, set the write-protect tab on the medium. Only use this procedure if the medium is unstable or unusable.
If a master medium becomes unusable, use the following procedure to recreate the master media for Remote Storage recall use.
To recreate the master media
There is a potential for lost data because the copy was older than the master that was in place. This allows for the recovery of the data up to the point where the media copy was last updated. At this point, the original master is marked "bad" and all data is accessed through the recreated master.
