Re: Assistance with doveadm backup...
Ok, so for lack of any other information, am I to conclude that the doveadm backup command is broken in 2.0.9? I have been through the wiki for it back and forth and cannot make it work. Yes, I need to upgrade, there is no question, but I won’t do that without a maildir backup. I would prefer to use the built-in dovecot mechanisms for that than something else.

Okay then. Is there a document on how to do that in place? That was one of the reasons I was trying to do a backup first.

Re: Assistance with doveadm backup...
Okay, apparently I’m just a complete idiot. Why doesn’t this work? doveadm -Dv backup -u user Maildir:/mnt/maelstrombackups/vmailbackup With user being the actual user name. No backup is created, it just shows me the usage text. Jeff > On Feb 20, 2019, at 10:11 PM, SH Development > wrote: > > I am having trouble locating examples of how to use doveadm backup.

Re: Assistance with doveadm backup...
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.

Re: Assistance with doveadm backup...
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?

Re: Assistance with doveadm backup...
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.

Assistance with doveadm backup...
I am having trouble locating examples of how to use doveadm backup. All the examples I see are for sync. 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? Jeff
