[SOLVED] Yet Another Backup Script for Community Version

[ArcaneMagus]

su - root
echo $PATH

I believe that is what he is trying to get you to run. This will output the contents of the $PATH variable, showing where your shell is looking for executables.

Thanks ArcaneMagus:

root@zimbra:~# su - root
root@zimbra:~# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
root@zimbra:~#

the only thing I notice is that the binary sizes on your system are smaller than mine, but then it's a different distro so that probably explains. It wouldn't hurt to update the various binary packages the script uses, but otherwise the right binaries appear to be in the right place with the right permissions. Unless there's some unique typo's in your copy of the script that we can't see (feel free to attach the script here) i'm out of ideas

Attach is my code that you requested. Let me know what exactly I have missing in the code.
Well, when I check the backup this morning, I still have some of the same error message and a new one. This is the message that came up in the log:

I have my script attached. Can someone please help me with my backup. I don't want my system to crash without any backup of mails. Please help...
Thanks

[chewitt]

the script appears to be moaning about the -A variable $CURRENTFULL which is defined earlier in the script by the following code:

CURRENTFULL=`ls -A -1 "$ARCHIVEDIR""$BACKUPWEEK"*$FULL_PREFIX*dar 2>/dev/null | cut -d . -f1 `

You can test the code on your system by replacing the $variables with the appropriate config for your system and then manually running the command from the shell, e.g. (on my box)

[root@zim]# ls -A -1 /opt/zimbra-backup/current/41*FULL*dar 2>/dev/null | cut -d . -f1
/opt/zimbra-backup/current/41_Zimbra_Backup_12-October-2009_FULL

It looks like you're making a DIFF backup, but if the script doesn't work on your system have you been able to make a FULL backup for the script to find with this code? ..if not (and the code returns nothing when you test it on your box) this might explain why the script fails at this point? If that's the case what error do you see when making a FULL backup?

The email error means your OS uses "sendmail" for the "mail" command but sendmail can't be found in /usr/sbin/sendmail .. Can you confirm that it's installed?

NB: I see that you cut/pasted one of my tweaks into the script, it's nice to see someone reads them! Please be aware that the tweaks are cummulative and you've missed one where I changed the name format of the Backuplist file. Your script uses the original code name to create the Backuplist file, so if you ever set ATTACHLIST to YES the name of the file created and the name of the file the attachlist tweak looks for won't match and it'll fail. At the moment you have ATTACHLIST set to NO so this doesn't affect the other issues you've got.

I don't think sendmail is installed. I am not sure if installing sendmail will affect my zimbra installation. Let me know how it can be installed without affecting zimbra.
Thanks

You can install it but you just make sure it's not set to start on boot.

I have installed it and took care of all the other errors I have been having before the backup doing what it is suppose to be doing now and this is the log with some few more erros:

[chewitt]

well.. you've added a new problem by changing the config to use the "copy archive to external host" function which is failing to connect over SSH. The script is attempting key based auth but you've either not got a key or the right type of key (rsa in your current config) installed. There are plenty of FAQ/HOWTO's on setting up key-based SSH auth, you just need to get that working so you can use SCP from the shell.

and sendmail based "mail" still doesn't work. I suggest you experiment with some manual testing of "mail" using the -v (verbose) option to see the SMTP dialogue. Sendmail Error 69 means "resource unavailable" ..the question is which resource? ..the SMTP dialogue might shed some light on that.
