Brilliant, not much more to say. I have 4 pc's and each one has a copy of rollback rx. Takes but a second for a snapshot and since it is a mini OS there is no problem getting to it even through a BSD.
Their Rollback Rx is an absolutely indispensable utility to any PC it will work on. But...
I have had major trouble getting it to work with my AMD based PC. After installation the software stops running after the first couple of reboots. Could not get an answer from tech support. Same problem occurs with Deep Freeze & Drive Vaccine (two of their competitor products).
So far Acronis True Image as the only operational way for me to enjoy snapshot technology on my AMD System.
