Files in several places.
WHAT SYNCHRONISATION DOES
Keeps the same files identical across devices and a service.
WHAT THAT MEANS
A change on one device appears on the others.
WHY THAT IS USEFUL
Work continues on any device, and files are not lost when one fails.
WHAT PEOPLE MISUNDERSTAND
That it is a backup.
WHY IT IS NOT
A deletion synchronises. So does a corruption, and so does an encryption by malicious software.
WHAT TO DO ABOUT THAT
Keep a separate backup that the live system cannot alter.
WHAT TO CHECK
Whether version history is available, and how far back it goes
WHAT TO BE CAREFUL WITH
Editing the same file on two devices simultaneously, producing conflicts Large files consuming your connection while synchronising Storage filling on a device with limited space
WHAT TO CONFIGURE
Selective synchronisation, so not everything downloads everywhere Scheduling, so large transfers avoid working hours
WHAT TO WATCH FOR
Files marked as conflicted, which indicate a simultaneous edit.
