We have the following:
BEXEC 2014
2 Tape Libraries (4 drives in one library and 3 drives in the other)
Several NDMP backups
Mon-Thurs Incrementals
Fri-Sun Fulls
The problem is the space being used on the media and having to reorder more and more LT05s
On the incremental days, there are 10-12 tapes being used. Before pulling these tapes out, we notice that the majority of them have like 90% of the tape unused.
The incrementals go off-site for a period of 4 weeks (OPP) and then come back to us to repeat the cycle.
Is there any way we can use the exact or close to exact number of media without tape space being wasted?
One waywould be to simply place the x number of LT05s into the libraries each night as opposed to loading both libraries with 50 LT05 tapes (normal habit). Is there a way that something can be configured in BEXEC to fill up the tapes in use befor emoving onto a fresh one.
APP periods are set to 24 hours so there is more than enough time for the tapes to be appended to. Typicall all our Mon-Thurs jobs take about 12 hours to complete (all of them).
Thanks
