I´m using only one stream, actually.
I would be glad if I could got 30 MB/s or a little less...
but 12 MB/s is not acceptable.
thx

How fast does a single (one stream) backup jobs run?
I'm wondering if you're thrashing the disks to hard with 8 streams.
BTW, 70MB/s is a stretch for LTO2.
IIRC, I thought the spec was 30MB/s native / 60 MB/s compressed.
I don't think I've seen over 40MB/s per drive.
