Sorry for being such a newbie when it comes to scripting. Created a directory for the backups on the network mounted volume. Changed the appropriate path and am getting this:

dsync(root): Error: user nfsnobody: Initialization failed: Namespace 'INBOX.': mkdir(/mnt/maelstrombackups/vmailbackup/nfsnobody) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /mnt/maelstrombackups/vmailbackup, euid is not dir owner) dsync(root): Fatal: User init failed Backup done for user: nfsnobody ... dsync(root): Error: user vmail: Initialization failed: Namespace 'INBOX.': mkdir(/mnt/maelstrombackups/vmailbackup/vmail) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /mnt/maelstrombackups/vmailbackup, euid is not dir owner) dsync(root): Fatal: User init failed Backup done for user: vmail …

After running the script, I suddenly have two new directories in my vmail folder, “nfsnobody” and “vmail”. What are these users?

No worries, that simple script should get you to a start though. Just replace the path with a mounted NFS share if you want it to reside in a network volume.

Spent the last couple of hours poring through the postfix list and just forgot where I was at.

Hi Jeff,

This should be better off to dovecot's mailing list. But just to get you started, this is the first thing that came to mind:

example:

for users in doveadm user "*"; do LOCALPART=${users%%@*} dsync -v -f -u $users backup maildir:/tmp/backup/$LOCALPART echo "Backup done for user: $users ..." done

I simply want to create a backup to a network volume of the email server's vmail folders. The goal here is to have a reasonably current backup should the main drive on the email server go south.

We currently authenticate our users from a mysql database. User’s mailboxes are stored as domainname/username/Maildir

I assume what I will wind up on the network volume is a duplicate directory structure as the vmail folder on the email server?

Can someone help get me started here?
