How to keep two different volumes on a network sinced

[magister]

Several years ago I settled on allway sync (http://allwaysync.com/). For some reason I preferred it to Goodsync, can't remember why at this point. It has worked very well for me (Windows, but deals fine with syncing to my Synology NAS). I didn't know about SyncToy. If for some reason SyncToy doesn't work out, check allway sync. It's free for personal use, but if you start start dealing with very large amounts of data (like terabytes of music files . . . ) they want you to buy the pro version. This is all spelled out on the web page; it's a tad cheaper than Goodsync.
