After firmware update to 6.9.0 my backup software can't work properly over SMB
Hey, looks like latest firmware update somehow broken my backup pipeline. I'm using Veeam Endpoint to make automatic everyday backups to the NAS over SMB. But after firmware update it can't work pr...
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.
Thanks for your detailed reply, Skywalker
I've passed your post to the Veeam support, they passed it to developers for the investigation.
