Would you share your experiences backing up cyrus mailboxes ?
What tool/s do you use ? how many backups a day do you run ?
Enabling delayed delete and delayed expunge will help a lot:
delete_mode: delayed
expunge_mode: delayed
You'll also want to modify your expire line in cyrus.conf to something
like this:
delprune cmd="/usr/local/cyrus/bin/cyr_expire -E 1 -X 7 -D 7" at=0100
-D and -X control how long deleted and expunged items remain on-disk:
-D delete-days
Remove previously deleted mailboxes older than delete-days (when
using the "delayed" delete mode).
"Older than" is a confusing statement. According to my notes this means
a message is kept for a minimum of X days from delivery, not X number of
days *after* it is deleted. I don't know why my notes say this, but I
remember testing it and convincing myself it is true. So -X / -D may
not do exactly what you are assuming they do.
Am I wrong? (and are you certain I'm wrong?)
Not sure if expire works that way but ipurge does for sure. If you have
a message that has been sitting in your mailbox for one year and you
delete it today than ipurge -d30 will purge the mail,
