# This script:
# 1. Backups the mailbox database to the portable text format,
# and compresses the result. This backup can be used to restore
# the Cyrus mailbox database using ctl_mboxlist (after uncompressing
# the backup file).
#
# 2. Cleans up any leftover crap in .stage directories.
#
# 3. Runs chk_cyrus and outputs warning messages (so that cron
# sends them to the administrator) if any problems are detected.
