I am using LTO 4 and LTO 5 tapes for long term tape protection on our DPM servers and would like to know if any one has any tips on monitoring the life of the tapes. I believe, as a rule of thumb, that about 260 uses of each tape should expected before the tape is retired and replaced, but I can't find a report or command in DPM (2010) which lets me know how often each tape has been used.
Any help would be greatly appreciated,
Thanks
Chris
