Re: doveadm backup has problems with some accounts

Because, that perhaps the version missmatch of the servers coul'd be the issue , and centos 7 eol comes in two months, i setup a complete new main mailserver, based on ubuntu 22.04 (24.04 was not out on starting to setup the stuff) so now both servers had dovecot 2.3.16.

But it doesn't help, still the backup jobs abort in the middle of the transfer, now with complete different error messages.

On the destination server i started it with the following command ( the corresponding user folder & files is deleted under /var/spool/vmail and /var/indexes )

/usr/bin/doveadm -D -v backup -t 1200 -Ru user1 tcp:mua02.domain.intra:12345

The first run is finished with the following:

Both servers are synced with the same ntp servers and have the same time when i check it.
