Let the storage substrate compress if possible - eg modern tape drives do it on their own. Or if it doesn't, you might compress the "archive of everything" file (eg a tar or dump file). Otherwise you have to do "special" stuff on restore; it's untidy. This position is a gross simplification of things of course. Example: there are systems I backup with rsync to a new hardlinked tree from yesterday's snapshot. Obviously this is 1:1, with incremental cost. It goes to tape from an uncompressed tar file because the tape drive does some compression. -- Cameron Simpson <cs@xxxxxxxxxx> DoD#743 http://www.cskk.ezoshosting.com/cs/ MS-DOS, you can't live with it, you can live without it. - Lars.Wirzenius@xxxxxxxxxxx
