Hi emninger

That  [  does not belong there.
restore=UUID="3b305a3c-d95b-4f80-b1fa-b7baaf7db06f"
Since it's the same as what you specified for the  tce  directory, you don't need that. Tinycore will restore from the  tce
directory by default.
home=UUID="3b305a3c-d95b-4f80-b1fa-b7baaf7db06f" opt=UUID="3b305a3c-d95b-4f80-b1fa-b7baaf7db06f"
These two items specify that you have persistant  /home  and  /opt  directories, so they don't need to be included in
your backup. Open your  filetool.lst  file, remove any lines beginning with  home  or  opt, then run a backup.
local=UUID="3b305a3c-d95b-4f80-b1fa-b7baaf7db06f"
I doubt you need this, but since I don't really understand the purpose of this code, I'll defer to someone else to
comment on it.
