mkdir backups/n800now login to your n800 Make sure you are not connected to the n800 via USB
ssh root@n800ipwhere n800ip is the ip address of your n800 I didn't have any luck with rsynch or scp because of looped symlinks so use the tar across network method
tar -cf - / | ssh regx@linuxboxip tar -xf - -C /backups/n800If you get errors you might have to backup the directories one at a time
tar -cf - /usr | ssh regx@linuxboxip tar -xf - -C /backups/n800to backup the user dir
tar -cf - /home | ssh regx@linuxboxip tar -xf - -C /backups/n800for the home dir ...etc
