I am tough to please but I have to say Synology’s Cloud Sync package does a pretty excellent job of sync and selective sync to Google Drive and so I am not sure why I would want to run Insync on my Synology DiskStation. But I would love to hear why it would be helpful.
Now, LAN sync. Wow. Wow would that be cool. My Clients and I do a lot of video editing and have terabytes of archived video that we need access to on an ad hoc basis. Insync allows us to grab a hundred or so GB of data down off Google Drive when needed and have it backed up while we work but waiting for things to come up and down from the Cloud is time consuming and being able to do this at GBE or 10gbe LAN speeds while letting the NAS work around the clock on syncing to Google Drive and subsequently to regional offices is ideal.
The new file compare feature coupled with some other LAN sync tool is a start but man would LAN sync be nice, having the entire solution wrapped up inside that clean Insync UI is a real winner.
Good luck with the progress on that team! We appreciate you.
