Hi
Currently we backup from various servers to a VTL, then Dupe to LTO2
But we have noticed some odd transfer speeds
I can watch the backup speed up to 50-70MB/s for a few seconds, then it drops down to as low as 600KB/s
then after about 5 seconds it'll speed up again to around 50-70MB/s and repeat.
It'll do this while copying one large file btw.
I've tried altering buffers etc but to no avail, and bakbone said network congestion which im not sold on.
We run a buffer of 65537 on the VTL and 8193 on the LTO2 Tape library
Netvault 8.61 on W2k3
Any suggestions?
