I see some information in the release notes for 6.0.1GA about backups now being zipped be default. I don't believe my cron job was upgraded with this feature however:

zmschedulebackup -q
Current Schedule:

f 0 1 * * 0-6 -a all
d 1m 0 0 * * *

I am interested in zipping for saving space. Backups currently only take about an hour, so I am not too worried about the additional overhead (or should I be?)

Found these instructions here:

Talk:CLI zmschedulebackup Network Edition only - Zimbra :: Wiki

zmschedulebackup -R f "0 1 * * 0-6"
then
zmschedulebackup -A d 1m "0 0 * * *"

It is not clear to me from this page where the -z argument should go though:

Zimbra CLI Commands

zmschedulebackup -R f "0 1 * * 0-6"
then
zmschedulebackup -A d 1m "0 0 * * *"

Rather not figure it out by experimentation.

Also, I am transferring the backups to another server with scp, and then putting them on tape for offsite storage. If I wish to delete the backups stored locally after a week instead of a month, would this be the correct second command? (with 1w instead of 1m)

zmschedulebackup -A d 1w "0 0 * * *"
