need second user with the same rights as root
Hi, I've been on this issue for a while, tried changing the root user name, so that root could not login as such, but as some other name, e.g. admin. But this did not quite work well.
Anyway, I need a second root user because I am doing periodic backups of the system and that user needs to be able to read ALL files on the system over SSH. I don't want root to be able to login over SSH directly and that other user needs to login without a password for automatic backups. Changing permissions for every file is not a good solution, because then I would have to always add this new user as the group and set read permission to the group on every file. I don't want files to be globally readable and I don't want to muck up the file permissions. There must be a way. There is even a backup user in my /etc/passwd file:
But that one cannot read all files either. ???
