I have just fired up the beta for the first time (V1.20 build 201)- and also as a first time FD-ISR user. I have been a RollbackRx user for sometime and was looking for something to replace that now that it no longer works in Windows Vista (which I use). My system Windows Vista Ultimate -a fairly new install, taking up about 18 gigs on a 350 gig SATA2 hard drive. My hardware is a fairly normal Pentium 4, 3 gig CPU, 1 gig RAM desktop computer. Installation was painless and quick. I make a secondary snapshot as soon as the installation finished. It said it would take almost 3 hours! I left it go at 1 hour elapsed and went to bed. It is transferring data at about 4.6 megs/sec. I am doing another snapshot now, and it estimated the time at 1 hour 4 min. There is still 45 minutes left on that, also transferring at 4.6megs a second. Nothing else is going on int he computer (except me entering these posts). I use Trend Micro as my anti-virus program, and I have just runed that off in case that is the problem. I have no anchored data. The task is on High Priority. the task has been going now for 24 minutes and it says it has 24 minutes to go (so the estimate is getting faster). But 45 minutes still seems way to long to a snapshot. I also use True Image 10, and that does a complete image in less time. mind, I guess FDISR is also doing a complete image. There is nothing else that I can think of that would cause this slow speed.
