I reproduced the issue using veeam Agent for windows,

See error message "Error: Incorrect function. Agent failed to process method {ReFs.SetFileIntegrity}."

Developter is checking the issue.

Thanks for your report.

For anyone have issues with Veeam, here's the deal.

6.9.0 included an SMB update. This update included support for a new FSCTL_DUPLICATE_EXTENTS_TO_FILE capability. This great new feature allows Windows to directly ask the NAS to clone a portion of an existing file, instantaneously and without consuming any extra space.

So Veeam now notices this new capability, and for some reason incorrectly assumes that the ReadyNAS must also support another capability, FSCTL_SET_INTEGRITY_INFORMATION. But this has not been implemented, and is thus unsupported.

Then Veeam calls FSCTL_SET_INTEGRITY_INFORMATION, and we reply that it's not supported. At that point Veeam errors out with the "Error: Incorrect function. Agent failed to process method {ReFs.SetFileIntegrity}" message.

So this really appears to be a Veeam bug, not a ReadyNAS bug. We could of course disable FSCTL_DUPLICATE_EXTENTS_TO_FILE to work around that bug, but then we'd lose a really nice feature. If anyone is in contact with Veeam at this point, feel free to pass along this information.

Let not jumps to defend Netgear, my problem is not with Veeam, I use Windows/NAS (Timestamp) and my backup got stuck "in progress". I reverted the firmware to 6.8.1 and it all work perfectly.

The issue is with Netgear that say don't downgrade the firmware but is not coming with 6.10 to fix the issue.

If we buy NAS drive for backup, we cannot afford weeks with NO backup just because Netgear is thinking about it.

Edouard users have posted with multiple issues and in the same thread. This does make it a bit confusing.

Some are using 3rd party software e.g. Veeam, and others are using the in-built backup jobs.

The issue you described with backup jobs being stuck in progress is fixed by the hot-fix for 6.9.0. Within about 15 minutes of a system running 6.9.0 booting up or a week if already running 6.9.0 the hot-fix would be installed automatically in the background. The hot-fix will also be rolled into the next firmware release 6.9.1.

When we do a major upgrade we may make changes that are not designed with a possible firmware downgrade in mind. If we always made changes with downgrade support that would severely constrain what changes we could make.

Once 6.10 is released, 6.9 will become a LTS series. At that point 6.9 will no longer get new features, but will get critical bug & security fixes. You may find that running firmware from a LTS series suits your needs.

the hot fix for 6.9.0 is it automatic or i can download from somewhere?

The hot-fix is automatic but may take time to happen. If you reboot the device then the hot-fix should download and be applied fairly quickly (15 minutes?).
The reported firmware will still show as 6.9.0! However if you downlog the system log files and check out the packages.log file within the zip, you should find the "readynasos" file version to be 6.9.0+4 (the current latest hot-fix as of 3rd Nov).
