I have successfully been using Acronis 9 Workstation to back up workstations to another workstation that has large drives. All backups work quickly and well. I installed a W2K3 domain controller on this lan and decided to start sending these images to a the server, and the backup times dramatically increased. Backups that had taken minutes were now taking many hours. I have done extensive testing and have proven that this problem is real. Here is a brief summary of my tests: -to determine whether the problem was caused by the workstations now being a member of the new domain, I removed them from the domain and logged in locally and still had the problem. -to determine whether something else had happened on the network that was slowing traffic, I ran numerous file-level backups and timed them. They all worked quickly and speeds were nearly 100 mbps. -to determine if other imaging programs had the same problem, I installed Norton Ghost 9. It backed up an order of magnitude more quickly than Acronis. -to determine whether your TI Server had the same problem, I temporarily installed Acronis True Image Server for Windows onto the workstation and it was just as super-slow as Acronis Workstation. -to determine whether this was a compression issue I turned compression off and the problem still exists. -to determine whether this was an issue with the one specific server, I tried backing up a workstation on another lan to another server, and the problem still exists. -Finally, I pointed the workstation backups back to the other workstation we used to use to hold backups, and it worked at the normal high speed it used to. There definitely exists a speed problem going to this server. Backups to another workstation are running at about 93mbps, but backups to the server are running at only 3mbps. There is no compression happening on our network switches. All workstations are on the same small lan and subnet. There is nothing special on this network. I then did some research in these forums and found that others are having this exact problem. Acronis engineers have recognized it but I could not find any solution posted.
