Backup is not archive!
Conclusion: Many organisations do not distinguish between backup and archive and assume their backup data is also their archival data. This makes the backup environment overly complex and difficult to operate and creates a very poor archival platform.
Organisations that separate these processes find that backups shrink significantly, resulting in much smaller backup windows and much faster recovery times. This also enables the archival data to be optimised to meet desired business requirements. That is, cost, retrieval time, compliance, discovery and so on.
