For computers that are not connected to a network, file synchronization can be achieved using a portable USB drive.
The objective is to synchronize files between a computer at home (Computer 1) and a computer at work (Computer 2), as shown in this illustration.
File synchronization is achieved in 2 steps:
- First synchronizing files on Computer 1 vs. a folder on the portable USB drive (1)
- Then using the USB drive at work and performing the same synchronization between the files Computer 2 and the same folder on the portable USB drive (2)
At the end of the process the same up-to-date files will be on both computers and on the USB drive, useful for backup purposes.
Steps 1 and 2 are repeated each time a synchronization is needed between the two computers.
