I bought Acronis True Image Workstation Echo (last April). I installed the server to one machine and tried to backup various machines over the network using the 'Agent'. My XP box backed up fine. My Vista box becomes unstable/slow. I also tried to backup a XP Tablet PC version one time which became unstable/slow. Initially I thought it was just an incompatibility with XP Tablet OS since I doubt many people use that. However, when I started using Vista and had the same problem, I dug deeper. I found that there is a memory leak which gobbles up all the RAM and makes the machine unresponsive/unusable. I used a process monitor to determine that during the backup snapman.sys memory usage continues to grow until the machine is unstable. Has anyone else had this problem?
