Backup
From Qmailwiki
What do you need to back up on your qmail server.
Contents |
Qmail Control Files
Back up these files:
/var/qmail/control /var/qmail/user /var/qmail/alias
Vpopmail
Vpopmail sites should back up the vpopmail mail directories
/home/vpopmail/domains
SquirrelMail
Squirrelmail stores user data like address books under the "data" directory. These directories should be backed up.
Rsync
rsync is a handy tool to do incremental backups across a network to a secondary machine. With the right configurations the secondary machine could automatically take over control of the mail server ( high availablity, hot failover, hot standby ).
Note: rsync does not automatically copy symbolic links which will cause all your ezmlm mailing lists to fail since they use symbolic links to .qmail-listname files.
Here are some sample rsync lines
# qmail control files rsync -aW --size-only --delete mail.inter7.com::qcontrol /var/qmail/control rsync -aW --size-only --delete mail.inter7.com::qusers /var/qmail/users rsync -aW --size-only --delete mail.inter7.com::qalias /var/qmail/alias # vpopmail mail directories rsync -aW --size-only --delete mail.inter7.com::vpopmail /home/vpopmail/domains # squirrelmail address books rsync -aQ --size-only --delete mail.inter7.com::squirreldata /var/www/html/webmail/data
