Hello Dovecoters,
I am using dovecot-2.2.10-8.el7.x86_64 on RHEL 7.4 When I backup mdboxes (using SIS) using this command doveadm -Dv -o plugin/quota= sync -1f -u us...@user.com mdbox:/mailbackup/user1 mails get backedup but all m files are not copied. Last file copied is m.4 If I run the command again I get below error I tried with doveadm backup command as well (many times). Error: Corrupted dbox file / mailbackup/user1/storage/m.4 (around offset=3732536): EOF reading msg header (got 0/30 bytes) Result is all mails are not backedup. Destination is a folder on a NAS with NFS mapped to the server. Thanks/DP --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
