depends upon configuration - default invoca.ch rpm's would have (and
thus RHEL/CentOS) distribution would have...
]# ls -l /var/lib/imap/db.backup1
total 9408
-rw------- 1 cyrus mail 144 Dec 6 09:20 annotations.db
-rw------- 1 cyrus mail 9573343 Dec 6 09:20 log.0000000005
-rw------- 1 cyrus mail 21336 Dec 6 09:20 mailboxes.db
# ls -l /var/lib/imap/db.backup2
total 9336
-rw------- 1 cyrus mail 144 Dec 6 08:50 annotations.db
-rw------- 1 cyrus mail 9500591 Dec 6 08:50 log.0000000005
-rw------- 1 cyrus mail 21336 Dec 6 08:50 mailboxes.db
thus there should be at least 2 backups of the mailboxes.db
automatically. Of course this doesn't supplant a decent backup
implementation.
