Hello, I am looking for a solution to the following business issue. Preferably a cloud based non-hardware, non-vpn solution. I have data files used by some mortgage software in my office (24,000 files across about 800 meg). Currently I have just shared the folder and the individual PCs accessing the data just set their data location as \\joes-pc\datafiles\ or something like that (the data location is set in the mortgage software). My main problem is that I am opening an offshore location and I need to have the remote users to also specify a networked location for the file storage. I have no vpn or other hardware other than wireless routers. Only a few requirements.....when one user has a file open if a second user tries to open the file (from the mortgage software) it tells the user the file is already open....there is no simultaneous sharing of a file and this needs to continue. I do not want to sync files from the cloud to local drives since I am guessing this would lead to all sorts of sharing issues. I basically need the files to act as if they are on my local network. I need the files centrally located, not distributed to users desktops. Secondary issue would be ensuring backups happen somehow....right now I just copy the files to a external harddrive once a week, but I really should at least use dropbox for this or something so it is done automatically. Used carbonite in the past and it encrypted the files in such a way that they were unrecoverable. Ideas???
