That's probably because the numerical uid's and gid's on your new  
server are probably different from your old server.

You mean that running that doesn't make username and groupname the  
owner? That's really weird. Do you get an error message of some kind?

In that case I guess you really should be fine when you create the  
user accounts and just get everyone's homedir files from BackupPC.  
You might need to chown the files (might also depend on how you  
restore (directly or via tar or zip)), but that really should be it.

You could try that, but maybe uid's start at a different number on  
your new install (did you install the same version of K12LTSP as you  
have on your old server?). You shouldn't have to do this, chown  
should be able to fix the files.
