That's what I'm using it with. A full backup seems to work fine although the checksum creation gave the error I put in my last post. I'll know if the differentials work ok after today

So this morning I come in and the follow was in /var/log/zim_backup.log

      Diff Backup started at: 03:00
/usr/local/bin/zmbac.sh: line 996: [: /opt/backup/zimbra_dars/30_Zimbra_Backup_28-July-2008_FULL: binary operator expected

and /opt/backup/zimbra_dars/Backuplist-29-July-2008.txt shows

Aborting program. User refused to continue while asking: /opt/backup/zimbra_dars/30_Zimbra_Backup_29-July-2008_DIFF.1.dar is required for further operation, please provide the file.

Any ideas??

Hi heinz, thanks for taking a look.

Here is the config section of the script. I did run the script with the install option.

Here is the info from dar, which I installed using the command 'yum install dar' as is the standard way on Fedora.

 dar version 2.3.4, Copyright (C) 2002-2052 Denis Corbin
   Long options support       : YES

 for details.

I'm not sure what the problem is with the md5checksum, as if I run the process manually it works fine. Just that the part of the script that said it had the error is where it is performing that function.

Hi there!

One thing i can point out is that you should put an email address in the CC field e.g. also use "thefold@mycompany.co.uk".

Your version of dar is some what newer than my prod version, and there might be some options or format changes in the syntex.... who knows, I would need access to that version of the sw to debug:

One more question, does /bin/sh point to dash or bash ?
Best it should point to bash!

/bin/sh point to bash

I had some progress with this, I have managed to solve the problems where I was previously getting the error:

    Diff Backup started at: 03:00
/usr/local/bin/zmbac.sh: line 996: [: /opt/backup/zimbra_dars/30_Zimbra_Backup_28-July-2008_FULL: binary operator expected

by changing the line (996) from

elif [ $CURRENTFULL ]

to

elif [ "$CURRENTFULL" ]

However I'm still getting the error

Writing a diff backup called:
                30_Zimbra_Backup_31-July-2008_DIFF

/opt/backup/zimbra_dars/30_Zimbra_Backup_28-July-2008_FULL.1.dar is required for further operation, please provide the file.

Dar had a problem!

Which as you said is a dar problem. I will try disabling the encryption for the time being as trying to enter the key on the commandline doesn't seem to work for me.

Hi

Can any one post the command to restore DAR backup file file1.dar with encryption command option. Iam using open source backup script to take backup.

I assume the script you're using is the one from this thread? This is a more appropriate place for your question.
