Backup script didn't complete via crontab

[snake_eyes]

Hello,

After long time of tracing of my matter which is the backup script didn't complete via crontab (It export a zip file its size 500MB) unlike when I run it manual (It export a zip file its size 2.2 GB), I noticed that during execution in the terminal it show the following messages:

tar: zimbra/data/postfix/spool/public/cleanup: socket ignored
tar: zimbra/data/postfix/spool/public/flush: socket ignored

tar: zimbra/data/postfix/spool/private/virtual: socket ignored
tar: zimbra/data/postfix/spool/private/scache: socket ignored
tar: zimbra/data/postfix/spool/private/old-cyrus: socket ignored

I think because it show the socket ignored messages it didn't complete, in this case please advise if what I said is true otherwise how I can solve the above issue?

Here is the crontab command:

30 16 * * * /usr/src/backup/ZimbraBackup.sh 2>&1 >> /var/log/crontab_zimbra.log

Those errors can be safely ignored. Sockets would be created when ZCS is restarted anyway. Are you error checking in the script ? And if so at what point does it return a error ?

Hello uxbod,

Really I'm tired from this matter, look when I execute it manually from the terminal it completed as I mentioned with the tar.gz file 2.2 GB unlike when I execute it via crontab it export and tar.gz with 500 MB approximately,

Here is my script:

Please note: it took 12 minutes via crontab and 20 minutes manually, so what's going on?

Any suggest gentleman?

[uxbod]

Can you post the output of ZimbraBackupFull.${DATE} ?

[snake_eyes]

Yes sure...

Check this link out: http://ubuntuway.net/ZimbraBackup_20...4-30-01-PM.log

Cheers,

[uxbod]

And the interactive one ? That way we can compare what is happening differently between the two.

[snake_eyes]

Here is the completed task via terminal which is export tar.gz 2.2GB

I am also having this problem. The script runs fine when executed from the command line and creates a 22GB tgz, but when it is ran from the crontab it only creates a 500MB tgz file. Has anybody solved this?

[snake_eyes]

Still I'm getting the same problem and I don't know how I can solve it because it is unexpected behavior

can any one know how to solve this? where are you experts?
