When you delete files, the space formerly accounted for in the active file system now gets accounted for in the .snapshot area. Snapshot space consumed grows as you delete or modify files, and the more you change the larger the snapshot area becomes; think of snapshots as measuring the "delta" in a file system.
It would really be great if there was a snapshot deletion daemon that could delete the oldest standard (hourly, nightly, and weekly snapshots only) snapshot(s) when the snapshot usage goes above a certain number.
So, "snap" could do a "snap highwatermark" command or something like that in a similar manner to the "snap reserve" command.
