I am experimenting with backup and restore procedures.

The FAQ page on backups says: "... you can backup mailboxes with tool like rsync or other backup tools. ... Folder /var/vmail/vmail1 must be owned by user vmail, group vmail, permission 0700."

As rsync cares about owner and permissions, and not really being a Linux person, I'm wondering which of these options would be best vis-a-vis the source and destination systems:

1. Back everything up as root on both machines, and reset ownership and permissions (to user vmail) only after an eventual restore operation.
2. Create a vmail account on the destination with same password, and backup as user vmail (would require changing vmail account to allow logon, which seems insecure).
3. Create a separate "backup" account on both machines with access to vmail folders (would still require resetting ownership after a restore though).
4. Some easier / better way I don't know about.

Any thoughts greatly appreciated!


Re: Backup Best Practices

The owner/group/permission must be applied AFTER restored on iRedMail server, it doesn't matter on backup copies.


Buy me a cup of coffee ($5) to support iRedMail:
