HiEverybody,
I just bought a Seagate STD224000N DDS-3 12/24 tape drive and used MSbackup to put a folder containing 55GB of information onto a dds3 tape. I expected to use three tapes for this job but it only took one!
Is it possible to get a 4:1 compression on these drives? I am sceptical. I tested the tape by restoring to another location and all the information seemed to be there.
The only possible explanation that I can think of for this is that the information I am storing is primarily TGA image files. they are usually 1.5 MB in size and about 1/3 of them are Alpha channel output, meaning that they are mostly black images...I believe black images compress to a smaller size in Jpegs but I would not expect this with the tape drive information.
Has anyone experienced this? any help would be appreciated
