Question Plesk Backup Manager auto-creates SSH keys

Hangover2

Regular Pleskian
Server operating system version
Debian 10.13
Plesk version and microupdate number
18.0.49 Update 2
Hello,

on some of our Plesk servers we have a strange behavior of the Plesk Backup Manager.
If a subscription is bound to a chrooted shell or SSH access is even forbidden, a backup (e.g. only configuration) will create the .ssh directory in the subscription including SSH keys (id_rsa + id_rsa.pub).

Is there a reason why the SSH keys are auto-generated?

At the moment we still investigating which plugin or configuration does trigger this behavior as we do not see it on all of our Plesk servers.
