Does anyone have a working solution as to how I can use "doveadm backup" to back up a virtual users mailbox to a removable USB device.

I keep receiving numerous errors and no files are backed up although the directories are created.

Well, a solution I demonstrated in our previous thread on this same topic works for me (doveadm user * plus dsync.

The thread got derailed into into discussion of how to use doveadm backup properly to have a one-step backup of all the virtual users, but it was sadly inconclusive.

All-in-all, we need to see exact commands you run and exact error messages you receive to be able to do suggestions or at least informed guesses.
