Yes, however... It also backups/restores the guisettings.xml file, which can be different from one Kodi client to the other in case of different hardware. Copying from one RPi2 to another should present no issues.
Thanks! Can I manually remove this file before restore? Or from the backup?
I am using latest OpenElec on RP2. Can I create a backup on it, copy it externally and then on a new LibreElec install restore the backup to have my addons and video library?
