Matt,
Thanks for responding.
Actually, I'm embarassed to admit that the retention parameters in the
copygroup for the AFS policy set were retaining deleted data for a year. So,
I would have had to wait a year before the AFS data was reclaimed from the
tape. I've since updated the retention parameters, and the tape space has
been freed.
I did write a synchronization script for the buta backup data. Unfortunately
the butc backup data is all written to a single filespace. That is another
drawback to the butc dump implementation. The only way that I have found to
see the backup data from TSM output is to execute a 'query occupancy' on each
tape in the AFS storage pool, and then search the output files for the backup
dump ids. This is not a nice implementatoin. The butc convention of
creating a filespace for each dump was much nicer.
I think that I am going to adopt the convention of creating a new TSM node
name with each level 0 backup. That way, when the data is no longer needed,
I can simply remove all of the backup data for the node.
Are you using buta for AFS 3.6? I didn't think that was supported.
