Roxio Backontrack vs. MS System Restore

I know that the entire Roxio backontrack suite can do more than Microsoft's System Restore, but this question only concerns the "Instant Restore" feature of the BOT suite: What is the difference, if any, between the Roxio Instant Restore feature of that suite and the System Restore in Win7?

Thank you,

The main features/differences.

Roxio backontrack suite
- file/folder based snapshotss
- snapshots do not get larger with defrags
- you can retrieve previous/deleted files by navigating in the snapshots


Microsoft System Restore
- sector based backups (at least for vista and 7)
- defragments make the backups grow larger
- you can retrieve previous/deleted files either by mounting the snapshots or by using the "restore previous versions" menu (in 7).

MSR add less overhead than BOT.

edit: Since I just managed to "break" Microsoft System Restore (Windows7), another differense is reliability. It seems that file/folder based ISRs (look FD-ISR and Roxio BOT) are much more reliable than their sector based rivals.
