I'm testing our backup and recovery process. For backups, we shut down cyrus-imapd (installed via Simon's rpm's) and postfix, use cpio to backup /var/spool/mail and /var/lib/imap and /etc, then restart cyrus-imapd and postfix.
I've built a restore server, installed postfix and cyrus. Here is what I would like to do:
Create a test user and mailbox to verify that SMTP & IMAP are working together properly. Remove test mailbox and delete user Stop postfix and cyrus-imapd Restore /var/spool/imap and /var/lib/imap Make sure all files/directories are owned by cyrus:mail Copy user entries back into /etc/passwd and /etc/shadow (I'm using passwd for Cyrus authentication)
At this point, do I need to run reconstruct? If so, any options? I'm thinking I don't need to use it at all, since I stopped postfix and cyrus-imapd. Am I missing anything?
If the contents of the mailstore is static when you do the backup/restore, then reconstruct *shouldn't* be necessary.
In regards to restoring just an email that someone accidentally deleted, how does this sound:
Create a top-level folder that will be the restore target Restore the contents of the directory containing the user's folder that needs to be restored into the directory containing the restore folder reconstruct that folder, and grant access to the user After the users has copied over the missing message to his own mailbox, remove the restore mailbox.
It can be done a lot simpler than that, and without having to involve the user. Since message UIDs are guaranteed to be unique, no existing message will have the same UID as a deleted one. You can simply restore the deleted messages directly into the mailbox from which they came and then reconstruct the mailbox to get them added to cyrus.index and cyrus.cache.
I do this more frequently than I would like, but its works just fine.
