Cron Job doesn't appear to be backing up correctly

[jimgrove1985]

ISSUE TYPE: Bug Report / Question (as this may be user error on my part)

ENVIRONMENT VERSION:

• Zmbackup Version: 1.2.6
• Zimbra Version: 8.8.15_GA_4018.FOSS
• Linux Distribution & Version: CentOS 7.9.2009 Core

SUMMARY:
If I manually run the "zmbackup -f" command as the user: zimbra, a complete backup appears to be created of all accounts on my mail server and it produces a full backup of around 3.4GB.
However, leaving the /etc/cron.d/zmbackup file to do it's thing does not produce the same results. For example, if I delete all existing backups using the zmbackup -d command and then leave the backup to run via cron overnight, it only appears to create a full backup of 45MB

could you show me your cron job

[jimgrove1985]

Strangely it looks like it may be working fine now.

I have just checked the backups and it generated a new full backup on Sunday, which is as to be expected based on the cron job settings and this was the expected full size.

I shall keep an eye on things for now and report back if I notice anything unexpected

OK, so I've left it running for a few days now and something definitely does not seem correct.

Here is the output of zmbackup -l ran under the zimbra user:

I am using the standard cron job file that is created when installing zmbackup.
It looks like this:

                         ZMBACKUP CRON FILE                              

This file is used to manage the time and day each backup activity will be
executed. Please modify this file rather than create a new one.
Default values for each activity:
Full Backup: Every Sunday at 1:30 AM
Incremental: From Monday to Saturday at 1:30 AM
Alias: Every day at 0:30 AM
Distribution List: Every day at 1 AM
Backup Rotation: Every day at Midnight
