Cloudbackup your files

DSM comes with a few apps for Cloudbackup. HiDrive backup, Elephantdrive etc. I've tried a few but I wanted to try something else. With DSM 5.0 we got "Cloud Sync", that ables you to sync your cloudstorage (dropbox, googledrive etc.), and since GoogleDrive's priceplan was alot more attractive (and understandable) compared to many others I wanted to try this out. The drawback is that you only get a plain backup (no versions of files etc), but if you can live with that, keep reading. :)
Cloud Sync has a few annoying limitations. You can't sync different folders to your cloudstorage, you can only have one folder which are synced. To get around this limitation, there is a way, assuming you have some space on your harddrives.
Setup a backupjob on the NAS to copy all your desired folders to your syncfolder and this will get synced!
It's an easy way to do this, but not prety since you have to store your files twice.

The filesystem on the NAS (and Linux/Unix) supports something called "symbolic links" where you can "map" a folder to another location without having twice the amount of drivespace. Sadly, DSM doesn't come with proper functionality to support this (not for mortal users anyway). CloudSync ignores Symbolic Link-folders anyway even if you manage to do it so.
