ISSUE TYPE

Question

ENVIRONMENT VERSION

Zmbackup Version: 1.2.6
Zimbra Version: 8.8.15
Linux Distribution & Version: Ubuntu 18.04.6 LTS

SUMMARY

Mailbox backup files are empty (0 bytes) when "Public Service Host Name" is configured.

STEPS TO REPRODUCE

1. set up a domain (mydomain.com) with "Public Service Host Name" (mail.mydomain.com).
2. run  zmbackup -f as zimbra user.
3. view backup folder content:
    -rw-r----- 1 zimbra zimbra 4.3K Apr 25 17:47 me@mydomain.com.ldiff
    -rw-r----- 1 zimbra zimbra    0 Apr 25 17:47 me@mydomain.com.tgz
4. open domain configuration and remove "Public Service Host Name" setting (leave empty) and safe.
5. run  zmbackup -f as zimbra user again.
6. view backup folder content:
    -rw-r----- 1 zimbra zimbra 4.4K Apr 25 19:53 me@mydomain.com.ldiff
    -rw-r----- 1 zimbra zimbra 377M Apr 25 20:03 me@mydomain.com.tgz

ACTUAL RESULTS

When "Public Service Host Name" is configured, the mailbox backup files are empty.

Is this an expected behavior?

if you set public hostname, then domain only can use this spcific hostname, so you will need change server hostname on zmbackup.
