Running the backup with Symantec Backup Exec at work used to require only 1 DLTtape VS1 tape to complete the backup. Lately it has been requiring 2. We use a set up 10 rotating tapes. The tapes have been in use for about 2 years now.
I do notice some Soft Write Errors on each tape (About 12000) Also about 800 soft read errors
We have about 100GB of data we are trying to backup. Get disk seems to be giving us a different compression ratio. Some 1.19:1, some 1.22:1. Both of these seem low.
What I do not understand is that one day the backup completed with 101400560621 bytes on 1 disk.
The next day the backup requited 2 tapes with 101,362,470,112 (Different tapes).
Is there a way to improve the compression ratio for the tapes, would new tapes fix the problem?
We really do now want to have to purchase a different tape drive is possible.
