6.0.2 Huge increase in disk usage?

[quietas]

Hopefully the Zimbra Devs will eventually give us a switch in the GUI to enable to disable at least basic compression and even better would be varying levels of compression.

My solution was to remove two of the 146gb 15k SAS drives from my RAID 10 and add a pair of 1tb 7200rpm Nearpoint SAS (enterprise sata basically) to the server for use as the HSM. This enables Zimbra to move all data older than XX days to the slower/cheaper HSM storage. I also added a new backup folder there and changed my backup location accordingly.

We are about to upgrade from ZCS 5.x to 6.x and I am unclear on how to set the backup jobs to use the non-zip individual files method as in ZCS 5.x. By using zip (compressed or uncompressed), not only will the storage requirements increase dramatically but so will the backup window since full backups will require all files and can't take advantage of the hard links. Can someone tell me how to restore the 5.x backup functionality after upgrading to 6.x?

Thanks,
Rob

After upgrade,

su - zimbra
crontab -e

Locate the section that starts with # BACKUP BEGIN and insert the --noZip switch (capitalization is important here) to the first two lines. E.g.

# BACKUP BEGIN
0 1 * * 6 /opt/zimbra/bin/zmbackup -f -a all --noZip  --mail-report
0 1 * * 0-5 /opt/zimbra/bin/zmbackup -i --noZip  --mail-report
0 0 * * * /opt/zimbra/bin/zmbackup -del 1m --mail-report
# BACKUP END

Then save/quit and crontab will update.

Be sure to double-check this setting after each upgrade, and vote for bug 45634. If you ever do a manual backup, make sure you do it via CLI, not GUI, and include the --noZip switch. Vote for bug 45635.

Thanks. I thought I had read a few times that you should not to edit crontab directly. Is the issue there that ZCS updates will overwrite any changes made manually?

I will definitely vote for that bug.

Thanks again

Yes, I believe updates will overwrite the changes. Conceivably they could be overwritten by other things but probably only if someone runs zmschedulebackup. Not sure if anything else calls it.

Basically, manually editing crontab is our only option right now.

I've become somewhat paranoid and I have another crontab job (outside of the zimbra user) which notifies me if '--noZip' disappears. As of now only patching, or reusing zmschedulebackup, has caused it to change.
