Because I'm always connected to the network in my IBM office, I didn't see an immediate need to set up IBM Connections Files sync. Recently, however, there was an unexpected network interruption, meaning I could not connect to anything, including the document I needed to work on that hour. If I had file sync activated, I could have continued working on my draft locally for the short hour or so of the outage, with my changes synced when connectivity was restored.
My advice: Even if you work full time in an office, set up Connections Files Sync today for your key files so you can keep working from your local drive during any rare connectivity interruption.
