Important note about permissions
--------------------------------
Using root likely will be required if you want to backup files of other users
or the operating system. If you only back up your own files, you neither need
nor want to use root.
Avoid to create a mixup of users and permissions in your repository (or cache).
This can easily happen if you run borg using different user accounts (e.g. your
non-privileged user and root) while accessing the same repo.
Of course, a non-root user will have no permission to work with the files
created by root (or another user) and borg operations will just fail with
`Permission denied`.
The easy way to avoid this is to always access the repo as the same user:
For a local repository just always invoke borg as same user.
For a remote repository: always use e.g. borg@remote_host. You can use this
from different local users, the remote user accessing the repo will always be
borg.
If you need to access a local repository from different users, you can use the
same method by using ssh to borg@localhost.
