just my 0.05 cent
and please bear with me if it's already been said
by far, the best solution i've seen for folder sync is FolderShare (http://www.foldershare.com
there are however some problems (which can be deal breakers !)
- 10000 file limit per folder (you can sync up to 10 folder)
- sometimes the folder share server does not work, and in that case the sync does not work...
for my backup need i use SyncbackSE (which is very good)
well in any case FolderShare is the best app i know along with autohotkey and FARR
so you may give it a try, if the limitations are ok with you
i use it for collaborative work and it's just such a productivity boost...
i could not live without it
FolderShare is the only app i know that is really unobtrusive and real-time...
from what i recall mirror folder is real-time until the destination is offline... (am i wrong here ?)
I've also tried (but not fully tested) PowerFolder (similar to FolderShare)
