I have a Dell PE 1800, running Windows 2003 R2 SP1. (updated BIOS and patched to current for SP1) I am running True Image Enterprise Server 9.1, build 3854, which according to Acronis is the newest version of the software. I have an Aberdeen XDAS 501, SATA to SCSI (U320), 2.7TB useable, external array. It is setup as a GPT drive as it is bigger than 2TB. Windows can see it just fine and I can create, delete, and move data no problem in Windows. My problem is that reading the Forums, Acronis claims that TI will work with any hardware that Windows will "see". If I try to use the ext drive as the location for a backup, the program freezes and the memory usage goes throught the roof and doesn't stop. At the same time dumprep.exe starts cranking up, which I would think means the program has encountered a fatal failure. If I kill TI, dumprep goes away. I don't get any error messages other than the usual "not responding", just a freeze up. I've tried editing the existing task, and I've tried creating a new one. Same result once I point to the ext drive. I even copied an existing full backup archive over and it makes no difference. It won't use that drive. If I can't get this to work, this software is of no real use to me. In testing months ago, I could save partition images to another server I have with an external array attached (only 1TB size though). I was hoping to use TI for the disaster recovery end of things and also file backup. It is really starting to look like it is not reliable enough for either. If anyone has any ideas, they would be appreciated. Thanks.
