cyrus management

su -l cyrus -c “/usr/lib/cyrus-imapd/ipurge -f -b 0 user.tmp” // cleaning mailbox
su -l cyrus -c ‘/usr/lib/cyrus-imapd/reconstruct -r user.tmp’ // mailbox recovery

cyradm –user cyrus –auth login localhost

su -l cyrus -c ‘/usr/cyrus/bin/ctl_cyrusdb -rx’ // db recovery attempt
su -l cyrus -c ‘/usr/cyrus/bin/ctl_cyrusdb -r’ // db recreation

su -l cyrus -c ‘/usr/cyrus/bin/reconstruct -r user’ // reindexing

2)
to make a regular backups /var/spool/imap/ and /var/lib/imap/, without stopping cyrus,
in this case there’s a danger of some data inconsistency and maybe some e-mails lost.
3)
In case of disaster just copy mail directly from the backup to the mail store directory (/var/spool/imap/user/%username%),
And run:
/usr/lib/cyrus/bin/reconstruct -rf user/username
4)
all quotas (in /var/lib/imap/quota/%firstletter of username%/)will not be reconstructed, so it should be done manually.
5)
all subscription and seen info (in /var/lib/imap/user/%firstletter of username%/) will not be reconstructed, but it can be restored from the regular backup.
