Does turning archiving off save space in archive files?

My understanding of archives is thus:

  1. When an archive shift occurs, a new primary record is added to the new primary archive for every tag on the system. This then fills with data.
  2. When a tag's primary record is full, an overflow record is created for further data for that tag.
  3. When the archive is 'almost full' of primary and overflow records, an archive shift takes place and we return to step 1.

My question is, does step 1 also apply for tags whose Archiving attribute is set to False?

The reason I ask is that we need to collect data for a large number of tags (around 1.2 million) but only for a limited time span. Once we have finished collecting this data, any new primary records for these tags would be empty (the interface will not even be running) and just use up space in the archive. We could delete the tags once we have finished but then we will also lose access to the historical data we have collected.
