Hello all,

I am facing problems when backing up using the doveadm in the stock version that has come through Redhat (dovecot-2.2.10-8.el7.x86_64 on RHEL 7.4).

On another server I have dovecot repos direct on a Centos 7 machine and that version of doveadm (dovecot-2.3.1-1.x86_64) does not throw any errors.

If I install the latest dovecot version using dovecot repos and then if issues arise and then if I revert back to Redhat repos will it cause issues with index files or SiS data?

Regards

DP

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 user1@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
