Cron Job doesn't appear to be backing up correctly #161

Open jimgrove1985 opened 3 years ago

jimgrove1985 commented 3 years ago

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

ENVIRONMENT VERSION:

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 commented 3 years ago

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:
