OneDiff error performing second backup

Good morning,

I'm using xsibackup (free version) since many years for simple full backup of my ESXi vms.

Some days ago I've upgraded to xsibackup-pro and I'm doing some tests before put it in production.

I've performed a first onediff backup from one host (6.5 VMFS5) to another (6.7 VMFS6): the first full copy was OK
After about 1h I run it again but, ufortunately, the job stopped with 2 errors:

ERROR DIFQMSH4 error: first 500M mistmatch
and
ERROR DIFDELAL  error: Remove All Snapshots: Remove all snapshots failed

Here is the command line I used to test:

./xsibackup --backup-point="192.168.0.229:22:/vmfs/volumes/datastore1" --backup-type=running --backup-prog=onediff --mail-to= "" --use-smtp=1 &

Please, tell me if you need more information to analyse the issue

Best regards

Re: OneDiff error performing second backup

To perform a Onediff backup you need to meet some basic requirements:

- The VMFS version must be coherent between the servers, you can't Onediff from VMFS5 to VMFS6 per instance.
- The target ESXi system must support the HW version of the VM you are replicating, which doesn't seem to be an issue in this case.

Apart from that, checking the disks via checksum may throw an insight into the state of your disks.
