Hello, perhaps I just don't know how to word it right, but since recently I have the problem that if I add one file to a folder FFC and other backup programs as well make me resynch the entire main folder.
I work on OS 12.7.1 with FFS 13.2 donation ed.
After having the problem in FFS I tried Carbon Copy Cloner and Super Duper to no avail.
I have big video files so when I add one clip of 500MB FFS says I have to recopy 1.2 TB to the other backup drive. When I go into the subfolder and compare them, they show no need for synchronization but going into a hundred subfolders is a huge work and won't work as a regular back up.
Anybody having any idea what causes this problem? That would be swell!

When you run a comparison, what does FFS list as the reason for needing to resync the files that haven't changed?

What type of comparison & sync are you running?

How did you determine that?

If your Compare is by Content & if your manual look at the directory is by size & date, it is very possible that the content did change (like if you have a failing disk) [where size & date need not necessarily have changed].

Or, something like a third party program (perhaps Windows Media Player ?) may have added meta-data to said files - again without changing the files size or date.

Hello,
thank you for your replies!
The reason given is always that it doesn't exist on the right size. In the meantime I realized that I might have several problems, among others differing hard drive formatting (journaled and APFS) I will address this first and get back after that. I also keep getting this error, completed with warnings, Database file is not available: Setting default directions for synchronisation, is that related? Cheers! Jul

> The reason given is always that it doesn't exist on the right size.

This suggests you are not using the proper left-right base-locations.
If you are sure your right-side files are in the desired location,
then you should define your left and right base-location such that
the path to your files relative to your left and right base location
is identical.
