I have made some overhaulin of my script and added file transfer functions, read below. The script can be downloaded <Here> for convenience.

Changes as of 2008-03-08:
-------------------------------------
for those of you who have been using this script re-download the code since there has been some bug fixes, non critical but still.

Following bug has been fixed:
When running the msg option it created a extra folder called 0 in backup dir/store which resulted in double 0 folders in backup folder, ex,
backdir/store/0/0 should have been backupdir/store/0.

have been expirence some issues in ubuntu when running the script via crontab, though it is not limited to this script but rather an issue with the packaging with tar option, if you are running this script in crontab add following at the end of each line where you call this script, > /dev/nul 2>&1l ex.
0 23 * * * /opt/scripts/ZimBackup.sh full > /dev/null 2>&1

Changes as of 2008-03-09:
-------------------------------------
- Fixed issues with this script when running from crontab
- added more backup options.

Changes as of 2008-04-18:
-------------------------------------
Script has been updated with new functionality that enables file transfer with ftp & scp protocols.

Another one, the more the merrier.

Thanks for writing the script and posting it here, would you mind putting a copy of it on the wiki in the Backup & Restore section?

[soulskater]

Thanks.

Sure i will put it in the wiki, just have to figure out how.

[soulskater]

Script has now been updated, see first post for latest version.

[soulskater]

Another update, now the script should be ready for the wiki, will post when it is there.

I want to rsync resulting file/s should did I modify the the script properly?
code is toward the bottom. I have the remote computer set up for automatic ssh authentication.

#!/bin/bash

# This script will do various backups of Zimbra depending on wich you choose,
# most of them are cold backups except the msg backup wich hot copies the 'store'
# folder for possible individual mail retrival. Be sure to change the variables below
# to point to where you got the zimbra folder and where you want it to be backed up to.
#
# This script must be run as root or a user with equal privileges or it will not work.
#
# Usage: ZimBackup.sh full	- For full backup (Cold)
#	 ZimBackup.sh diff	- For diffrential backup (Cold)
#	 ZimBackup.sh msgfull	- For complete message backup (Hot)
#	 ZimBackup.sh msgdiff	- For diffrential message backup (Hot)
#
# When you run this script via crontab be sure to add '> /dev/null 2>&1' at the end
# of the script like below or the tar command will fail for no apparent reason.
# 00 12 * * * ZimBackup.sh full > /dev/null 2>&1

Anyone interested in seeing backup options improve should vote on this poll initiated by Zimbra:

Vote: Hot Backups for FOSS?

Hi.

Have tried you command with slightly changed parameters, only minor and it looks like it works, below is my line as a tested it from the console directly.

rsync -e ssh -varuzP /opt/backup/ user@server:/destinationfolder/

The diffrence is that i put a username to the line and can't see one in yours, can be due to editing the script for insertion here...

Have you tried the script?

[uxbod]

If the same user, as the one performing the backup job, is on the remote server and the keys have been exchanged then a specified user should not be required.

I second dwmtractor's comment, please vote on the FOSS backup poll

[soulskater]

True, but that was not the case in my enviorment.
