In “normal Commvault Operations”, Should I have tapes in my tape library that have “Last Write Time” set as a date (not empty), and on them a write session (or a few), but the data on the tape is 0 bytes and no associated storage policy?
For all storage policies/tape copies (except a few) we have “infinite” retention set on the tapes. For those that do not, retention is “years” (except the DR tape(s) . We do not re-use tapes.
I have several (like 40 tapes) with “Last Write Time” set to a few days (or weeks… a few are months) ago, etc and all are0 bytes. Not all tapes in the system that are 0 Bytes have Last Write Time set. Using ‘tape → view contents” shows “no data” (as expected). The tapes show they have been mounted (“Number of mounts > 0) and there sems to be a file marker or 2 on them.
So: I’m wondering how to tell “what its writing to them” and why or if “this is normal” as part of some internal 1 time “tape validation/initialization” job or something… but that doesn’t explain why some tapes have > 1 write (usually 2 or 3 writes)
