Ever since I switched to windows phone I've sorely missed having an official dropbox app. Recently I've toyed with the idea of moving all my crucial files to SkyDrive instead. I have more storage on SkyDrive and the WP SkyDrive integration is very handy.

I'm thinking about having both cloud sync services point to the same local folder for the first few weeks. That way if I want to go back its an easy task (and I can keep using dropbox's superior public folder)

Has anyone else done this? Are there any potential issues (permissions, conflicts etc)

I see no reason pointing Dropbox to a folder called A service formally known as Skydrive instead of Dropbox would cause a problem. –  Ramhound Aug 13 '13 at 11:25
    
I'm just thinking two cloud based apps will be syncing the folder. I wonder will they interfere with each other or cause any latency or locking issues –  roryok Aug 13 '13 at 16:52

To my knowlege neither Dropbox or The service formally known as Skydrive uses local files ( within their syncing directory itself ) to handle the syncing process. Please note the Skydrive is quickly changing how it works, Windows 8.1 provides native support, and currently the location cannot be changed. –  Ramhound Aug 13 '13 at 17:23
    
Thanks ramhound. The dropbox location can be changed so I'll probably point that to the SkyDrive folder –  roryok Aug 13 '13 at 21:52
    
Actually it turns out that I can only place the dropbox folder within Skydrive, which is not what I wanted. =( –  roryok Aug 23 '13 at 9:55

I have done some tests with sharing the same folder on different clouds (One Cloud, Google, dropbox,...)lately. To be honest, it seems to give nothing but problems. In fact, the files seem to be in 'sync mode' all the time and the services take a lot of memory resources. I think the reason is the following: one cloud (f.ex. dropbox) sees a new file and starts synchronising. Once done, it seems that something on the folder or file is modified. The other cloud starts syncing as well. Once done, dropbox sees a change in the file and resyncs. But so does the other cloud when dropbox has synced. So both clouds seem to be syncing all the time.

This is likely to be highly OS-dependent. The inotify syscall in recent-ish linux kernels, for instance, allows listening for modification vs access without locking issues; and I would guess any cloud client would be using the right ones. –  tucuxi Oct 25 '13 at 9:30

Cloud services will always timestamp their synch folder on your device with the time of their last synchronisation. How exactly they do this may vary from service to service.

If the synch folder is shared between services, the second service will see the date change of the first service as an update and will then go off and try to synchronise.

This can get you into a deadly embrace situation where everything is synchronising all the time.

I find it easier to have a daily run of robocopy (on Windows) to synchronise the two local synch folders. That does mean that you have two copies of everything on your local system but I have put each service's synch folder on a separate local hard drive so there is additional redundancy.

I haven't tried this on a phone so can't say if this is feasible there.

yeah robocopy seems like a better solution, although maybe more often than once a day (on the hour maybe?) Not sure what you mean about trying on a phone as we're talking about desktop clients! –  roryok Oct 25 '13 at 10:40
    
@roryok: The original question started "Ever since I switched to windows phone", so I assumed that is the device where the client was being set up. –  Chenmunka Oct 25 '13 at 10:45
    
ah, yes, I see how that's confusing. I just wanted to shift priority to SkyDrive on the desktop to match up with the phone, as I mostly use Dropbox at the moment –  roryok Oct 25 '13 at 10:46

I´m testing LiveDrive (paid) service for it´s 14-day free trial full function period. LiveDrive has 2 functions: As a Backup in the cloud (all or some folders you want) and more interesting for me "LiveDrive Briefcase".

LiveDrive Briefcase creates an "L:" virtual drive at your PC (or MAC) and automatically syncs all the files or folders you have created inside your local "L" drive to the cloud. But the problem (as on most cloud file sharing services) is that you can´t map other local folder than inside "L" to sync (and get by the way... get backed-up).

I have a Little office and some folders shared within 8 PC, so I won´t move files or folders to another place inside my PC because probably this will interrupt my local sharing network at office. But maybe moving folders inside "L" drive was an approach. So I think rather than copy my selected shared folders to the L drive, the solution will be move these folders to the L drive. But I can´t do this. The L (virtal) drive accepts only to copy inside but not to move inside... so if I want my files still resident at it's original location I need to think another solution. (Because copied files in "L" location will not be visible at my local network and/or maybe not be shareable and maybe cause problems with duplicate files, etc Note: "L" drive is a virtual drive so copy files inside it not eats space of your hard drive. Then I think: yes... L drive accepts only created or copied files inside it, so I need a solution to automatically copy files (back and forth) between L drive and my selected folders to share these folders not only locally but on my cloud LiveDrive service (Briefcase).

I search and found an oldy little free software that can automatically sync one or many folders or files to another drive or folder. Either in one direction or other or fully back and forth. This tiny an usefull software is DSynchronize (google it to find and download).

So my final solution was:
1) Install LiveDrive Briefcase (the paid cloud storage service best suit my needs and best priced) at my "server" PC where my locally shared folders of my Little office network was located. This automatically created the "L" empty drive.

2) Then install the little DSynchronize software and configured it to autostart at startup (or you can setup it as a service if you want) and configure it to automatically sync my selected folders (copy back and forth between) to my "L" drive... AND THAT'S IT !!

RESULT: I´M VERY HAPPY !! LiveDrive Briefcase and DSynchronize works very well together. DSynchronyse maintains evenly, silent, fully automated ann instantly actualized copy of all my selected local folders to my "L" LiveDrive Briefcase drive, so then, all "L" content (a exactly up-to-date copy) is automatically sync to my LiveDrive cloud storage every moment, so I can use it anywhere simply loging in my Livedrive Account anywhere in any internet connected device.

Theremore, I can share a folder or many folders or a single file with my external partners or costumers by only sharing it by their email accounts (a convenient & simple feature of LiveDrive Briefcase) and then LiveDrive automatically emails to the recipient a link and user & password to get Access only to that folders or files. (my customer can see, download the folder or files I shared to him, but not edit or delete at my Briefcase, nor upload) so it´s my perfect solution.

And... BTW ... Briefcase is a convenient 2Tb (yes!!...2048 Gb) cloud storage at only US$25/month.

I hope this solution may work for you, and obviusly DSynchronize software can sync Dropbox folders or other free cloud service "dedicated" folder with another(s) local folders if you don´t want to copy or manually move your local content to it. So you can get more usability from any free or cheap cloud storage service thanks to DSynchronize free software.
