Backup of System State fails 0x80070013

Back Up's been working fine for me for over a month. However my scheduled backup on Tuesday failed, and so have subsequent backups.

This is only related to backing up System State - backups of anything else work fine. I get an error code: the media is write protected - 0x80070013 at about the 27% mark when trying to backup SS.

No hacks or new software installed or and Event Log gives me no clues. Backup in my Vista partition works perfectly.

Googled the error code and get no leads.

Any ideas, anyone?

Didn't work for me. Scannow found nothing, and System State backup still fails at the 27% mark.

Hello,

This is not expected.

It would be good if you could post this issue in our technet forums so that it can be better tracked here:
http://social.technet.microsoft.com/.../windowsbackup

To help investigate this issue, can you pl. collect the backup traces under %windir%\Logs\WindowsBackup, zip them together and send them across?

You can send the ZIP across to sriramb-nospam@microsoft.com (remove the -nospam when sending mail).

Also, pl. mention the build you are running (assuming you are running Windows7 Beta, pl. confirm).

Thanks,
Sriram [MSFT]

This was resolved quite a while ago by upgrading my 7000 build to 7048. Since then, I've had no more backup issues.

I had the same issue with my windows 7 RC 7100 installation. Luckily i got it fixed and i blogged about it here:
