OSMC Backup fails: location of backup not provided

Hello,
I want to create a backup using MyOSMC.
The backup directory is /media/osmcbackup, and I have mounted a partition accordingly:

osmc@osmc:~$ mount | grep osmcbackup
/dev/sda2 on /media/osmcbackup type ext4 (rw,relatime,data=ordered)

However when I start manual backup I get this error:
location of backup not provided

Logs are available here.

Can you please advise how to fix this error?

THX

Have you restarted the mediacenter/rebooted the Vero after having set the location in MyOSMC?
Some settings need a restart of MyOSMC.
