May i suggest mounting the filesystems as ext2, if you are running ext3? I run 5 scripts for the snapshots as well. One is run every minute, and checks if there is less than 512M left on the snapshot, then it extends it. (this is actualy 3 scripts, one using find to execute another script, this one is called by cron, the 2. does a lvdisplay on the snapshot, and pipes the data into a perl script, that does checking and resizing + email sysadm (me)) The 4 other scripts are run every hour, every 8 hour, every day, and every sunday. They take a new snapshot, unmounts the old, mounts the new, and removes the old. Ontop of all this, i take backup using the day snapshot, and i'll soon (setting it up today) get another server, that i will use rsync to take a backup of the hourly snapshot to another server, which is identical.
