The data is mainly uncompressed raw video data (AFAIK HDF, I don't work with the data). Users come with external HDD's and copy the data on the samba files servers. Right now we backup 70 TB to tape, but I would like to get rid of tapes. For the large RAID volumes there is also no regular backup. We make it by acclamation. But this should change now...
