Change the camera roll backup destination folder
When I started to use OneDrive on my phone (doesn't really matter which one it is), OneDrive chose to backup my camera roll to a folder called "SkyDriven kameran kuvat" (it's in Finnish and you can see it uses the name 'SkyDrive' in the folder name). I have no idea why this folder name was chosen or why it chose the root of my OneDrive either.
I think it should be possible to change the name (and destination) of the folder to which camera rolls are backed up.
Their are many options in taking your backup one you can try using "Cloudbacko home" software i am basically using this software from long time and really satisfied using this software . It basically gives backup to your Mac as well and helps restoring also . I am leaving a link below just check: http://www.cloudbacko.com/free-backup.jsp
