I create a new volset file for each backup incremental, instead of
appending. The bu database will keep track of which file it needs to
restore a volume from. You can check the list of volset files required
by using "-n" to the backup restore command. It appears that appending
to a file does not work. I typically end up with 76 bu volset files per
semester. I have no problem restoring a volume.

Hi,
we want to switch from backup to tape to file based backup. We append
our incremental dumps to the full backup file. However, we are not
able to restore a volume for which an incremental dump exists, butc
only complains:
Restore
Restoring volume home.moeller.restored
Can't read FileBegin on tape
butm: unexpected tape datablock
Can't restore volume home.moeller.restored
butm: unexpected tape datablock
Restore: Skipping remainder of volume home.moeller.backup (536871263)
Restore: Finished
Strangely enough, we can restore a volume from the same file for which
no incremental dump has been appended, so it must have to do something
with the incremental stuff or the append-to-file.
butc is still an old 1.2.11 one, running on a remote machine - we'd
rather prefer to leave it that way for the moment than to upgrade the
backup server.
TIA
