Comment(by tomeu):

 Ok, so just to clarify and check if I understood correctly the spec, my
 part is to write a func like this:

 {{{
 path_to_backup_idx, path_to_backup_state_idx, path_to_backup_files_idx = \
     write_backup_index_since(timestamp, max_items=None)
 }}}

 That filters the items to backup according to timestamp and max_items and
 creates the following files:

  - backup.idx: file that contains the metadata of the entries to backup,

  - backup-state.idx: file with the ids of all the entries currently
 present in the DS (not filtered nor limited by max_items),

  - backup-files.idx: file with the absolute paths to the data files and
 thumbnails of the entries to backup.
