In my situation, I have millions of files which are mostly static. So simply walking the filesystem to find which files changed is the big time consumer. We were formerly backing this up via rsync, and it ran 10-12 hours per night. Then we switched to ZFS and now the incremental takes typically 7 minutes. Mark's LVM snapshots should be able to achieve similar results on this particular dataset. _______________________________________________ Discuss mailing list [email protected] http://lists.blu.org/mailman/listinfo/discuss
