system32\config\system corrupt or missing

I've tried amanda, clonezilla, partimage, g4u, linbox and FOG. All are good. Homeserver restores a differential snapshot. Ends up being an order of magnitude faster. Still faster is running the boot vol off a an iSCSI mount to a zfs backend where I can keep multiple snapshots and regress a fully fucked image in less than 5sec.

How many of them have you tried?
