# This script:

# 1. Backups the mailbox database to the portable text format,
|
| 9 |
# and compresses the result. This backup can be used to restore
|
| 10 |
# the Cyrus mailbox database using ctl_mboxlist (after uncompressing
|
| 11 |
# the backup file).
|
| 12 |
#
|
| 13 |
# 2. Cleans up any leftover crap in .stage directories.
|
| 14 |
#
|
| 15 |
# 3. Runs chk_cyrus and outputs warning messages (so that cron
|
| 16 |
# sends them to the administrator) if any problems are detected.
