I have a situation, have a full backup that was completed with errors (failed due to insufficient space in disk). Now this backup is quite large and from details I see that some 50 accounts has been failed, and all others completed successfully.

The account I am trying to restore is NOT in the failed ones so I tried restoring the regular way only to get this error.

Error occurred: system failure: Negative seek offset
I looked into mailbox.log for these activities.

I have tried using --ignoreredologs and -c switches under zmrestore, with no success.

I need to fix the error in the particular full backup and use it again. Can anyone help me please?? Pleeez! Ty.
