Synchronizing several computers

[Syncoholic]

Hi,
I'm running a Banana Pi as NAS and I need to synchronize two computers with my working folder.
So I generated a batch file, which synchronizes this folder every startup.

But now I have the second one set up and synchronized, the first computer announced the DB file was incompatible and started to synchronize the whole folder, again.

Is there a workaround for this problem?

Yes, update all FFS installations to the same version.

Thanks for your fast reply!

As you guessed, I' running different versions ;)
On the computer I'm running FFS for ages 8.7 is installed. On the other computer, the one I set up yesterday, 8.9 is running.

DO I have to update both at the same time from now on or doesn't it matter from now on if there are small version differences in the future?

Generally doesn't matter, unless FFS complains like in this case.

All right, thx!
