Windows 8 error code 0x807800C5 during Windows 7 File Recovery backup

The following error appears if you try to include a system image in your backup using the Windows 7 File Recovery backup tool.

0x807800c5

There was a failure in preparing the backup image of one of the volumes in the backup set.

Details: The mounted backup volume is inaccessible. Please retry the operation.

Error code: 0x807800C5

According to this forum

For Win 8 only: The Win 7 back up program included with win 8 does not support backing up a image file to any kind of NAS device (UNIX, Linux) . Internally the program gives an error that the NAS device has an incompatible sector mapping type. You can backup to a hard drive that is attached to a different windows machine and then back up that file to your NAS. Convoluted, but it works.

So, backing up a system image to a Samba share is out of the question. To work around this, disable the creation of a system image in your backup.

I haven’t tried backing up to an NTFS-formatted iSCSI LUN, which might work. If anyone has tried that, I’d be interested to know the results.

Error code 0x80070544 when attempting to back up Windows 8 onto NAS over Samba

If you use Windows 7 File Recovery to attempt to backup your system to a NAS device, you may receive the following error:

0x80070544: The specified network location cannot be used.

Verify the path points to a correct network location and that the supplied credentials can be used for write access to the folder.

The validation information class requested was invalid. (0x80070544).

The solution to this is rather simple. You have to prefix your username with the name of the machine where the Samba share is located. So, if you are backing up to diskstationbackups, prefix your username with diskstation.

In my case, my username on that device is mike. So instead of using mike as my username, I had to use diskstation\mike.

It works now. Enough said.
