Re: [BackupPC-users] sudoers

If your problem is just the permission and you already are using a copy of rsync why not use the suid flag ?
just be carefull with file permissions and ownship for security. just do the following on the machine you want to backup:

chmod 550 /path_to_copy_of-rsync/rsync
chown root:backuppc /path_to_copy_of-rsync/rsync
chmod u+s /path_to_copy_of-rsync/rsync

this will make the command rsync to run as root although you used user backuppc to lunch it, once again remember the line:
chown root:backuppc /path_to_copy_of-rsync/rsync
and be sure that no1 else is on group backuppc.

i use this setup to backup the backuppc server without using ssh (saving time, memory, and of course cpu cicles).
hope i helped
cheers,
