  It dosen not need to. In Perl you build a refernce withe 
  informaiton as required and then you serialize it with JSON
  and store in the database. 

  IT looks to me that your approach is based on a missuderstanding
  of the capabilties of mongodb.

  if your data is in $d

  $d->{ID}->{FILE1}=CHECKSUM1;
  $d->{ID}->{FILE2}=CHECKSUM2;
  $d->{ID}->{CHECKSUM1}=FILE1;
  $d->{ID}->{CHECKSUM2}=FILE2;

  I don't understand why we can't just do with one collection?

  No. Current has to stay as is. It is the link to the current
  directory. Pleae untar the next tarball into  temporary directory
  and then delete that when your are done. Otherwise all tihs will
  land up being mirrored.
