1) I have no option and cannot locate any parameter to set the overall size of total backup files for a given volume. I have several volumes being backup daily to incremental files that account approx to 2gb per day each. Although I have purchase 2 Tb of nas only for these daily security file backup, I am reaching the max after a couple of weeks. I sent a request to acronis support and got a one line response:"use backup server". After looking for this I finally found out an exe file with that name that I clicked and nothing is happening. I am under win xp pro sr2. Sorry but that looked like such a basic feature that I can hardly understand why one would have to be an engineer to manage to save his files. 2) since installation of this software, some disks (multiple raid high-end workstation) are not accessible by other workstation on my network. This is a very disappointing software so far... Please advise.
