How to execute full backup cmd from command line (via ssh)

Configuration
1

hi
when i execute fullbackup via web interface it shows it does something after a while i got redirected to /hassio page … and there is no backup in the listing …

seems something is broken? even there is freespace.
there is nothing regarding the backup in the logs … ie backup failure etc.

can i execute it from cmd line? thanks

it was “Exiting” bc of no space on the device … but there would be handy to have some pop up msg regarding that instead of just exiting …
