Before when I wanted to update my back up drives, Update took a few minutes to read the back up drive and then a few seconds to update. Now every time I go to update a backup drive it takes 2-3 hours (!!) to read my back up drive. Today right after after doing this, I added one document to my data drive and then tried to update the back up drive again. The program started reading the entire backup drive with an estimated time of 2 hours and 20 minutes. What am I doing wrong?

What settings are you using?
Have those settings changed from before (when it was quicker)?

Is it the comparing that takes a long time or the actual syncing?

Rube: I'm not using any settings, I just turn on FFS and browse to my D drive on the left, my F drive on the right and click on update.

Xenon: I think it's comparing. It's reading the entire backup drive before syncing. Once it's read the drive it goes quickly. Seems to me whatever did before didn't require the program to read the entire backup drive every time.

Another oddity is when I try to submit my response, I'm kicked back to the log-in page with a message saying I have to log in to submit. I now copy everything I write because I'm presented with a blank page so I have to paste in whatever I wrote.

If your left location is D:\ and your right location your (entire) backup drive F:\, and there is much other stuff stored on F: than the backup of (part of?) D:, then FreeFileSync (FFS) will Compare the entire drive F: .

Try to limit the scope of your sync by making your left and right location more specific to the sync, or use the Include and/or Exclude Filter to make FFS only Compare and Sync relevant folders.

Plerry: Thank you but that kind of defeats the purpose of why I've subscribed to FFS. Using Macrium I daily update back up my internal D drive (which consists of data I use regularly) to an external drive E.

Using FFS, every couple of weeks I then back up D to two external drives (F&G) that contain years of data and ensure those 2 are synced. One of those is kept off site.

There's no way I can keep track of and specify what folders, photos etc. in D that I happen to modify or add over multiple days. So selecting specific items to backup doesn't work

What I don't understand is that I don't remember having this problem before. I must be mistaken, but it seems to me FFS "knew" which files and folders needed to be updated without going through terabytes of data every time I plug in a hard drive. Apparently that is not the case.
