I'm contemplating an auto-loading tape drive as part of a backup strategy. This would be my first experience with tape backup. The cost-effectiveness of tape drives seems to depend on the assumption that they will provide many years of service. I'm having a difficult time assessing how many years of service to expect from a tape drive, however.
I have two solaris servers running Oracle Applications. One is SPARC 5.9 and other one is SPARC 5.10
I want to share the tape drive attached to 5.10 with other machine so that i can enhance my backup strategy for backing up Oracle DB.
I tried to share my tape drive by performing the below which I got it from one forum
We replaced one of our tape drives (attached to a SPARC Server) with an LTO5 one (external, attached vi SAS). Manually we check (using tar) that the OS can write data to the Tape Drive, however, the application backup is failing.
Since the application takes its own backup, the apps team opened a case with the vendor.
What things should I check to confirm that compression is actually happening on our tape backup system? Although the tapes are marked as 200G/520G (native/compressed) capacity, they seem to fill up before the 200G mark (some less than 100G).
