We're starting to look into LTO5 backup now. Does anyone have anything negative to say about the BRU software?
Thanks,

But, you can use LTFS formatted or the TAR-compressed file backups of the earlier tapes - and both are open source formats.But if you use LTFS, the archiving software can retrieve just the files you wish but (given the slower seek times of tape) if they are close together on the tape, it will probably be faster if you retrieve groups of files.

What is the time difference in retrieving data back if I need to fix a 3 shot section in an hour show? Will those LTFS LTO-5 drives appear like a media drive so I could in theory consolidate the necessary media back to my normal storage to do the fix?
