Is there any non-MS backup/recovery software that can use MS generated system image files?

Since it seems that Win7 can 'forget' a system image backup, is there any software that can directly use the files generated by Win7's system image app?
(acronis and others can transform a sys image to their type but any direct use software?)

If you perform a restore point earlier than a system image backup, Win7 recovery will NOT see that backup - MS must keep a track of backups somewhere other than in the many many files it produces for a backup!

I make sure to use restore points as a safety, first and foremost, then the system image backup as a backup to the restore points, restore points are cheap and quick, system images are slow and HUGE!!, and apparently unreliable to boot!!

PS: IE-9 RC install screwed up things, did a restore pt recovery and things still are screwy!! Be careful!!
