Do Acronis True Image and Acronis Disk Director programs support RAID arrays?
Yes Acronis True Image and Acronis Disk Director programs support all RAID arrays in Windows and almost all under Acronis bootable disc. There is a probability that Linux drivers (Acronis bootable disc is based on Linux) for a specific RAID array have not been included yet. You can use a special plug-in for the BartPE instead of the standalone version. This plug-in allows you to use Windows drivers for the RAID array when running Acronis True Image from BartPE bootable CD. See page 3 of Step-by-step instructions to create BartPE bootable disc.
