It appears to me that one of the problems with restores taking so long is
that the incremental nature of ADSM will, over time, spread the required
files over many volumes in a tape storage pool.  Requiring mounts, and
searches, of multiple tapes requires a lot of time.

Has anybody tried, say once a month, performing selective backups for entire
file systems in an effort to aggregate all the files required for a restore
in reasonable proximity to each other?   Incremental backups would then get
scattered but it may limit the number of tapes that would be required.
Would this help the restore time problem?

I'm considering such an idea and was wondering if anybody has had any
similar experiences that may help.
