I am planning to migrate our production cyrus-imap server to
a new server with the latest OS and cyrus-imap version. I noticed that the
latest version of cyrus is storing the emails on the filesystem differently
from the legacy ones. It is using uuid storage.
What are the good practice to :-
Nightly backup:
ON LEGACY CYRUS we do
1. Stop cyrus
2. Snapshot data volume and mount it
3. Restart cyrus
4. Take data backup on an external media
5. Backup configuration files
Is this procedure safe to implement it on the latest cyrus
version?
Moving user from one cyrus-imap server to another cyrus-imap
server with the same cyrus version:
ON LEGACY CYRUS we do:
1. Ask user not to use email
2. Redirect user's emails to another temporarily mailbox
3. On the source server I copy the corresponding email
directory and sub directories. Very easy to identify them
4. On the destination server I create single mailbox
with the email name.
5. I identify the filesystem directory associated
the mailbox just created and restore the data backed up in step 3
6. Reconstruct the mailbox.
This procedure definitely is at least not practical to
implement on the newest version of cyrus. Any suggestion how to transfer a user
to a different server?
Granularly restore a single email from backup:
ON LEGACY CYRUS we do:
1. Ask user to create a new folder in the email
2. Ask the user not to use the email
3. Restore the email file from the backup to the
corresponding folder on the file system
4. Reconstruct the mailbox
