Hi list,
we are backing up our netapp filer by ndmp. The tape drive
is connected via fibre channel. We upgraded the drive from lto-2
to lto-3 recently. However: the backup performance havent
changed since then (approx 25 mb/s). The new lto-3 drive should
come up with more than 50 mb/s....
This would indicate that the bottleneck in your system is NOT the tape
drives. In my experience LTO-2 should be able to run at more than
25MB/s, so LTO-3 should run even faster.
I have seen LTO-2 drives running at > 50MB/s.
You need to look elsewhere to achieve performance increases.
Incidentally MB is megabytes, mb (if it existed) would be millibits.
