I am getting this error below:

"File backup could not save your automatic backup settings for the following reason:

Transaction support within the specified file system resource manager is not started or was shutdown due to an error. (0x80071A91)

Please try again."

I tryed this (to fix) on cmd:

“fsutil resource setautoreset true C:\” as an adm

But did not work.

What I want is to make a backup of all my files.

Did you delete all files first from C:\Windows\System32\config\TxR before executing fsutil? Make sure explorer shows system and hidden files.

John see this blog post

Recently I was very frustrated installing Vista on my home machine. It’s not that something wrong with Vista, it was drivers that drove me crazy. Problems I had were caused by the fact that nVidia failed to provide working drivers for RAID 0+1 array based on nForce 4 Ultra chipset (I’ve got ASUS A8N-E motherboard). When I finally managed to install everything, it was running fine for couple of weeks. After certain point though Windows updates begun to fail as well as Vista backup feature stopped working. I had basically only one clue. It’s an error message I was getting when I tried to start a backup job:

File backup could not save your automatic backup settings for the following reason:

Transaction support within the specified file system resource manager is not started or was shutdown due to an error. (0x80071A91)

Please try again.

Microsoft help wasn’t really helpful: http://support.microsoft.com/kb/927748/en-us. Googling didn’t bring any luck either, so I start researching toward file system resource manager (FSRM). Accidently I found that fsutil tool has an additional argument “resource”, which evidently controls FSRM behavior.

So, if you see a bunch of failed Windows Updates and/or your Vista files backup doesn’t work anymore, here are the steps you need to do in order to reset FSRM:

Click “WinKey” on your keyboard. Type “cmd” and hit Ctrl+Shift+Enter. That will bring you to the command prompt in Administrator mode. It you still have UAC enabled, it will ask you for permissions, click “OK”. Navigate to your Vista system folder (i.e. C:\Windows\System32) Type “fsutil resource setautoreset true C:\” assuming that you have your Vista on drive C. Reboot.
