Backup speed has a big gap in the totally same environment

Has anyone got the same issue that when I tried the first backup, the speed was up to 70MB/S, but after that it always keep 20 to 30 MB/S. I tested it in the midnight, so the bandwideth was pretty low, and I could confirm no special apps were running then, which may occupied the bandwidth.

What's also abnormal was that the recovery time was much shorter if I resotore a VM, using the file I backup first, which reaches 70MB/S, than other file in 20 to 30 MB.

It really confused me, and thank you for any suggestion.

Re: Backup speed has a big gap in the totally same environment

I noticed that as well in the past. Not sure why because like you, I tested the backups at night with no other real traffic over the LAN. 

Turning on compression should speed things up. With compression turned on I went from about 20-30MB/s to a little below 109MB/s
