When I am doing this:

doveadm backup -f -n inbox -F /root/backup-accounts.txt tcp:mailxx.local:542

I am getting an error on the distributed storage, which I exactly did not wanted to be touched.

doveadm(testaccount): Error: remote(mailxx.local:542): User initialization failed: Namespace 'Archive/': stat(/home/mail-archive/testaccount/Archive/mailboxes) failed: Permission denied (euid=xxx(testaccount) egid=xx(xxxxx) missing +x perm: /home/mail-archive, dir owned by 0:0 mode=0700) doveadm(testaccount): Error: remote(mailxx.local:542): dsync-server: User init failed doveadm(testaccount): Error: Failed to start remote dsync-server command: Remote exit_code=75
