rsync to NAS for backup

[mick crane <mick.crane@gmail.com>]

I made a mistake and instead of getting a PC for backup I got a NAS.
I'm struggling to get to grips with it.
If rsync from PC to NAS NAS changes the owner/group of files to me/users 
which is probably no good for backing up.
There's that problem then another that it won't let me login as root.
I asked on Synology forum but not getting a lot of joy.
