I've recently started using EaseUs ToDo Backup, which has been running perfectly for a few days now. The program does a backup of various Folders & Files off my desktop at a set time daily to an external drive.
Recently I was sitting alongside the computer as the backup routine started, and I noticed that my NAS drive started up and started 'clicking' similar to the Read/Write sound.
I do not have my NAS drives selected for backing up by this program, so was wondering why this may be happening.
