I have been using NovaBACKUP for several years. My current version is 15.0 (Build 10).
I run it nightly and it backs up about 175,000 files with a total size of around 166 GB. Until three days ago, it was taking a bit under two hours to run. Three days ago, it suddenly started running much more slowly, and took 5 1/2 hours to complete. Two nights ago it took 4 1/2 hours, and last night it took about 4 hrs 20 mins to complete.
The connection from my Windows 7 Home Premium desktop to an external drive is a USB-3 connection.
I have two external drives that I alternate nightly, so the slowdown is occurring with both external drives.
Everything else on my desktop is running fine. I don't perceive a slowdown anywhere else.
Does anyone have any suggestions?
Thank you very much.
