Hello dear QRecall Community.

I am new to QRecall. Read a lot of good things about it and intend to purchase a key, but haven't done so yet as I have a question:
I'm coming from Intego Backup, which never really worked.
Why, don't ask me. Tech Support couldn't tell me either.
The program, despite not working, also created thousands of small, invisible .PBsyncDB files. I didn't like that and now my question would me whether QRecall does something similar.
QRecall says it only copies things that change, in a more efficient way. To get there, does it create such invisible log files?

Best, Thomas
