I would say, get a backup system that handles whatever bits you have
on your disk, or find out how to configure the existing one.

If there are some permission problems, maybe it needs more privilege
to do its job.

You can't ask every vendor of everything that you have installed
or "git pulled" to fix their permissions because your backup program
has bizarre limitations.
