[Which is better: sync one large folder, or several smaller?]

Is there any advantage or disadvantage to syncing two discs root to root, or would it be better to sync each of the containing folders separately?

 

That is - I could sync my 2TB discs F:\ to F:\ - and get all of the contents; or I could select the subdirectories one at a time: music, video, photos, etc.

 

Any reason to do on over the other?

[The Types of Things People are Using SYNC for]

Using it for a simple and free way to back up my files. I have ~2tb of files, which I keep on mirrored disks in my home office. I made a third copy (just using drag and drop) and then took it and an old netbook and placed them in a remote location, and then synced it to one of the home disks.

 

Now I have all of my files remotely backed up, so a local flood, fire, theft will not result in losing my files.
