I like the fact that we can archive cases to a read only state, however, there are some things I'm not a fan of about the archiving:

 

- Backups during upgrades see no improvement by archiving requests.  There should be an option to backup full, archives, active or trimmed (db only).  If have a scheduled backup, why do I need to backup the archived requests again during an upgrade?  Why not skip that data and cut the pre upgrade backup in half?

- Import/Export of Archive Data.  Allow archived requests and attachments to be exported to a zip file for long term storage.  No need to keep the data in the live DB for years.  If something needs retrieved, allow an archive to be temporarily brought in and data pulled.

- During full backups, why not split the archive and live data into 2 zip files?  I know currently my full backup is about 3GB.  I can only imagine people with larger instances than mine with larger files.
