i think you should use the parameter "Volume Use Duration" or "Use Volume Once". The Parameter "Maximum Volume Bytes" make only sense if your are using a DVD as media. > FYI, the total data of our clients is 15 TB, but we are told that this > data should at least double each year. > > I noticed that there seems to be a limit on the number of disk-based > volumes in a pool due to the suffix having 4 digits, i.e. 0001.
