Here is my command:

[root@mail maelstrombackups] #mkdir -p vmailbackup [root@mail vmail]# chown: vmail:vmail /mnt/maelstrombackups/vmailbackup [root@mail vmail]# doveadm backup -u jeff maildir:/mnt/maelstrombackups/vmailbackup

Only gives me the usage list, doesn’t work.

Not really. The suggestions in the post seemed to be:

1. Tar the whole directory, which I have tried in the past, but a 130G directory takes over 18 hours to tar.
2. It was also suggested to rsync the directory, but the question was brought up, and not answered, about whether it was advisable to copy live mail, thus the need for doveadm sync/backup.

Based on what I’ve read about doveadm backup, this is what I need, I am just having a hard time formulating the syntax for the command.

root@ketola ~]# mkdir -p /backup/sami root@ketola ~]# chown vmail:vmail /backup/sami root@ketola ~]# doveadm backup -u sami Maildir:/backup/sami <snip> root@ketola ~]# du -hs /backup/sami 211M /backup/sami

does this help?
