With release 880, Roon announced improved database integrity checking, so that it is supposed to be less likely to keep corrupted database backups.
Unfortunately, this is just less likely, since I‘m currently having an open support thread, where database corruption is the claimed source of my intermittent troubles and
- I‘m able to restore an allegedly corrupted database without warnings,
- I‘m able to back up an allegedly corrupted database.
So, seemingly no real safeguard, unfortunately.
My hope is, that support can improve database backup integrity for the community by investigating my case.
