Our tape drive has 8 slots. It is an SDLT drive, 160/320.
The movement of tapes to different media sets is a random occurence. In other words, it happens on both jobs at the beginng of the night and at the end.
We run a backup on 10 different servers. Nine of the server backup jobs use 2 tapes. This gives me capacity of 320 GB uncompressed.
The other backup job uses 1 tape, with capacity of 160 GB.
I have totaled the hard drive capacity on the nine backup jobs, and this comes no where close to the 320 uncompressed limit.
Furthermore, the one backup job comes no where close the 160 GB limit.
So there shouldn't be a problem of running out of space.
Any other thoughts?
