Is the --options=no-500M-check still valid for ver 11.02 and above?
Has this issue been resolved?

Hi,
I keep getting the same OneDiff errors.  This is for all running VMs on the server. One of which is (Xpenology)linux based and the other Windows 10.

Last error raised for the above VM:
ERROR DIFQMSH4, details: [ds3615] error: first 500M mistmatch [ds3615_2-flat.vmdk]

Last error raised for the above VM:
ERROR DIFQMSH4, details: [FD1] error: first 500M mistmatch [Win10_AMD-flat.vmdk]

Also, the corresponding VMs also create " accessible" namesakes with the "xxx_XSIBACK"

I have tried removing all snapshots, consolidating the VMs. Then delete the backup folders. And then restart the job again. Same errors still.

This is with 11.02 xsibackup Pro

Yes I checked the crontab at conf/root-crontab. Also checked that I did the --update-cron again. It even shows the msg " the service seems to be running ok"
And also check that the crontab is in the /var/spool/cron/crontabs/root crontab file. All seems to be there.

But the cron job does not fire

Been trying out new 11.0.1 free version. Backups fine, but my cron simply does not fire. I get no error messages, and the log file is empty.
What could I be doing wrong? any new permissions needed for any of the files?

Hi,
So the suggested solution is to change the NAS configuration to sync NFS if it was on Async NFS? How do you do that for an iscsi volume from a synology NAS?

Hi Daniel,
Nothing has changed from these windows VM , only the xsibackup version. It was all good before moving to ver 10.
I will try rebooting.
Does placing the hosts into Vcenter make any difference?

Hi,
I have  a similar error with 2 windows 8.1 VMs which will will make one VM will make it to 75% done, and the other to about 47% done because it gives the " Failed to clone disk: Input/output error (327689)" in the log.
This is with a cold backup.
The VMs otherwise boots and works fine.
How to diagnose what is wrong and remedy it?
