I have Retrospect for Windows installed on an HP z800 workstation running windows 7 sp1 64bit. I have dual Xeon X5660 which has 6 cpus each with hyperthreading and 48GB of memory. I am copying from an 8TB raid array which has a speed of 635 GB/s reading 4k sequential according to crystalmark 5. I am backing up to an 8TB seagate usb 3 drive capable of writing 170 GB/s 4k sequential.
I backed up 7098.3 GB at 2263 MB/min which took 2 days 6h and 33 mins.That is about 38 MB/sec which seems very slow.
Is there any way of optimising Retrospect with respect of writing to drives.
