How should I completely mirror a server user rsync, without using root password?

I use rsync to mirror a remote server. It is said that using a root password with rsync is dangerous, so I created a special rsync user. It seems to work fine, but cannot copy some files because of file permissions. I want to mirror whole directories for backup, and I guess this cannot be done without using root password, I mean if root does not give permissions on a specific files, no other account can read them. Is there other solutions and why shouldn't I use root account in rsync (I only do one way copying, that does not effect source).

If you want the whole server, then yes, you need root. However, instead of "pulling" (where you have a cron on your local server that does "rsync remote local"), can you possibly do it by "push" (where you have a cron on the remote server that does "rsync local remote"?) In this case, you won't need to configure the remote server to accept inbound root connections.

One option is to use an ssh login as root, but using ssh pubkey authentication instead of a password. In general, pubkeys are the wya to go, if you want to automate this later.

You'll want to look into the PermitRootLogin sshd_config setting, in particular the without-password setting or, if you want to get even more sophisticated and (probably) secure, the forced-commands-only setting.
