I tried to use the backup option for my 2 test os's (libreelec + rasplex).
I formatted a 8 GB usb drive (fat32) but when i check e.g the Libreelec file on maintanance menu, the drop down menu of "Destination drive" seems empty and i can not enable my usb (thus back up option is grey out - All other tabs like edit config/password/fix/reinstall/replace/info/alias are visible).
I have created a BACKUP folder in my usb with 2 folders (Libreelec and Rasplex)
Am i missing smth here? Haven t done this procedure cause i never needed it..
PS1: Oups my mistake. Had to create a folder named ''os'' on my usb drive. I m testing and will inform..
PS2: Ok, i 've tested it and it seems to work (at least for my 2 os's). I backed them up on my 8 GB usb drive (didnt change anything during the backup) and at the end i did get a notification saying "OS's backed up successfully".
Then i re-installed PINN on my fresh sd card and also restored my 2 backups from usb. I had those 2 names
Libreelec_RPi2
Rasplex_RPi2
Then i re-changed the alias names to whatever i wanted (not a big deal). It seems promising !
