Why won't windows server 2012r2 wbadmin backup start?

Question

Backup

Hello! When installing the Windows server backup component, it is installed but not active. Do not tell me where to dig further? Did wbadmin delete catalog does not help, reinstalled the component - it's useless. Before that, everything worked, it still gives an error that there is not enough free space on the disk where the backups fall. When I try to run wbadmin.msc, it says that the file was not found.
