Kijk ook eens in het logbestand van drive of je daar een reden van de update zien. Ik heb voor de aardigheid een file met naam "Fibonatie berekening" in "Fibonatie berekeningen" veranderd. Dat resulteerd direct in de volgende 8 logregels:

Er wordt dus erg veel gelogd. Op de mac staat het logbestand in "~/.SynologyDrive/log/daemon.log". Het is alles heel cryptisch, maar je weet nooit of je een reden vind.
