Let me explain why I asked this.
I re-read man page many times. I learned that default behavior is:
- map user/group names and fall back to numeric IDs if no match;
- provide mapping files to change default mappings.
There is no easy option to just store numeric IDs as is. Please correct
me if I'm wrong.
I can imagine (actually I deal with) two situations like these:
- I backup through ssh to remote/different server running may be
different distro and don't want UID/GID to be mapped;
- I restore from remote backup on the host I just booted from some (any)
live CD, and don't want IDs be messed up on either backup or restore
side.
Indeed I don't see any reason to map UID/GID in a backup. If we preserve
devices/mtime/ctime/whatever - why mapping user/group by default?
Having just simple option like --numeric-ids can be useful for some
group of users.

I thought free software needs user opinions. rdiff-backup is a great
product, irreplaceable in some aspects, and all I want just to help to
make it better.
