You shouldn't need to run hammer cleanup from cron every hour. I ran it
manually while downloading the mail headers. This deletes ephemeral changes
between snapshots; if a sector of a file changes five times between snapshots,
only the last is kept.
If you have deleted a big file, it will stay on disk until the snapshots
expire, which is 60 days in this example. To make it disappear faster, reduce
the number 60.
