Spontaneous Recovery mount

[Sciuriware]

Hello,
since 10.14.1 my TimeCapsule gave up (coincidence I presume),
so I dropped TimeMachine backup and started to use some other utility.
During TM backups I had noticed a short mount and umount of /Volumes/Recovery,
but since then, without TM activity, it appears to mount at random.
I umount it from Terminal, but later it comes back.
Anyone?
;JOOP!
