zmbackup -z question

[alto]

I want to zip the backups to save space and looked up zmbackup and zmbackupschedule. They both refer to -zip and -zipStore as being options that can be added but do not give an example of where to add the -z

This is zimbra user crontab

# BACKUP BEGIN
0 20 * * * /opt/zimbra/bin/zmbackup -del 15d
0 2 * * 6 /opt/zimbra/bin/zmbackup -f -z -a all
0 2 * * 0-5 /opt/zimbra/bin/zmbackup -i -z -a all
# BACKUP END

Does that look ok?

Does anyone have any opinion on to compress or not, does it slow down restores for example

Thanks,

yes that placement is fine. it doesn't matter what order arguments are in.

and yeah the tradeoff for compression is speed always. my advice would be to do it both ways, compare the results and decide if it's something that is worth it for you.

Thanks for the reply.
It will be interesting to see what size the next full backup is, last normal full backup was 67G

Well, what's the result?

Thanks, I'm interested in this for our servers, too...

Forgot to update this.

Full backups are now just under 40G quite a substantial reduction

OK, thanks. Do you notice a speed/performance problem now? Do backups take much longer?

[alto]

much longer

a full backup used to take 90 mins without compression

with compression that is up to 6 hours

the backup starts at 2am GMT, we have only a handful of users actively using mail during the night and they have not complained

OK, thanks for the info!
