Totally new to Legato Networker (7.4.4) and need to know how to make some tapes
re-usable for backups. Tapes appear marked as appendable but the % Used still
100%, Is the backup job going to re-use these tapes or do I have to change
something here in order to re-use them?? Step by step will be nice for this
newbie . . Hoping this is an easy one for all the experts in this cool forum.
Thanks for your help. [Question]
Note that "100%" does not mean "full". It just means that Networker has
managed to store as much data as at least the nominal capacity of the
tape. Compression can do funny things to that number. For instance, the
nominal capacity of my LTO-3 tapes is 400GB. So at 400GB written, its
"100%", but with compression I actually get often more than 600GB. When
writing to tape encounters the EOT marker, it will actually be marked as
"full". Until then, it will keep writing to them.
You probably want to make sure that tapes get filled as quickly as
possible so that the retention time of the data on that particular tape
would expire around the same time - then you can easily recycle the tape.
