I just finished rereading the "Restoring Files Can Be Slow" section of the manual. In it, it mentions doing a restore will be about 3 times slower than a backup.
Now I've got a situation where I have to remove sensitive data that was backed up on several tapes. The way I'm doing this is to bscan a tape so as to sync the content to a new catalog, then restore each Jobs in seperate restore jobs. Once every job has been restored, I search for the sensitive data, delete and then backup every seperate jobs in one single job. So basically I've got a /backup-restore folder that contains each seperate jobs in their own folder (ie. /backup-restore/01, /backup-restore/02, ... /backup-restore/98). I need to do this in order to prevent files with the same name to overwrite each other. Once I deleted the sensitive data, I backup the parent (/backup-restore) folder in a single job. The problem I'm having with this is that it took 5 days to only do the restore of each jobs. I had 98 jobs that bscan found and added to the catalog, all of which are about 100MB to 30GB in size. Here are the actual stats: | 99 | RestoreFiles | 2007-06-10 13:16:54 | R | F | 839 | 9,375,175,662 | T | | 100 | RestoreFiles | 2007-06-10 13:21:59 | R | F | 1,726 | 13,753,356,353 | T | | 101 |

+-------+------------------------+---------------------+------+-------+----------+----------------+-----------+ Am I doing this the most efficient way possible? Is it normal that each job takes progressively longer to complete? I'm getting the feeling the tape is rewinding and forward spacing a lot for nothing since I'm trying to restore every job on tape. Any advice or comments would be appreciated. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
