NV+ slows after 15-20 minutes [SOLVED]

I don't believe there is any issue with the tib file - the "poor media quality" warning is probably something to do with a response to a read that Acronis thinks is too slow.

I agree, and judging by the infrequent blinking of the access lights on the NV+ when this happens I believe that the NV+ has just stalled.

What makes this odd is that the NV+ is 2x the speed of the old Synology. Did you look at the network stats saved on the NV+?

That's an interesting comment. I recognise that the old sparc equipment is getting on a bit now, but always thought it was good in it's time. I think the Synology is probably a year or two older, but only has a 250GB IDE drive fitted so expected it to be slower anyway.

I didn't look at the saved network stats, but will happily do so & post them back if you can tell me where to find them - are they one of the log files that can be downloaded ?

Of course if the NV+ is sending JF despite the MTU setting, that could result in fragmented packets reaching the PC. That might create some lost packets/retransmissions which could maybe explain the error???

I looked at the lost packet / unrecovered packet information yesterday and reset the counters a few times. From memory on a typical failed transfer there was about 1000 resnt packets of which 250 were unrecovered. That seemed high to me, but not fatal ?

If you want to do your own work with wireshark, or even download the original captures from the other thread here then that should (based on godfreydanels analysis) show that the NV+ does send oversize packets. I stepped in before to try and help him because he thought the throughput rates were very low. I found the same, and upgraded memory/ switch to give myself the best chance I could for decent rates. Now I am finding that the connection is both slow and worse, now unreliable for large acronis restores. I have been messing about with some 5-8GB uncompressed image files for an Acer ZG5 with SSD and they have worked fine, taking ~20 minutes. When restoring a 20GB image to a Toshiba M10 with 250GB SATA I would guess it gets to 6-10GB and then starts to stall.

If you can let me know where to get the network stats I'll look at those and anything else that may be useful

Many thanks
