I was successful in installing and setting up owncloud but I am having problems setting up btsync. After reading tutorials it was suggested to install and use btsync and owncloud to make a "dropbox" clone. The problem I am having is setting owncloud and btsync to use the same folder (/medai/sync) where my usb drive is mounted.
In btsync I get this error: Don't have permissions to write to the selected folder.
What should I do?
Is it better to just use owncloud w/out btsync?
Owncloud provides the "dropbox" clone without using btsync, but if you want to add secure transfer - I understand that may be a valid addition to the mix.
That being said, your permissions for the file system will need to be enabled for the user running the OwnCloud server and also btsync. Typically this will be www-data on a Debian Apache server and btsync for the btsync portion. It may differ if you are using other than default components such as Nginx etc.
Set the permissions and ownership using chmod and chown, and make sure that the user running the btsync is also in the www-data group so that they can both access the files. To add a user to a group in raspbian, you can use something like adduser btsync www-data to accomplish this. As with almost all commands in Linux, you can use either/both of the options for syntax help - man <command> or (usually) <command> -h or <command> --help.
That should do the trick. But if all else fails, temporarily open permissions up to all users for the target files (chmod -R ugo+rw <folder>) and then let the system run for a moment and check what/who it is actually writing files as - then lock it back down to that user/group, using the commands above.
sudo usermod -a -G www-data btsync. To check: groups btsync.

www-data and your btsync is probably running as btsync , even though YOU are logged in as pi. The webserver is run via the services tools (aka, the system itself) and is set to run as www-data (by default). So, allow group read/write on the fileset (probably /var/www/owncloud) and ensure btsync is in the www-data group so that it can access the files as well.

chmod -R 777 wasn't a really bad idea. While there might be one that I have missed, it seems quite dangerous to suggest something like this to a rookie.

666, but I still think there should be a more elegant and less error-prone way to do this (e.g. using top/htop to check which user the services are running as).

I would take a look at .../.sync/sync.log
It's likely you're running into an open files limit, which effectively halts btsync. In may case I had to increase the number of allowed open files to 20000 and 50000 (soft / hard) in /etc/security/limits.conf.
