As data ages in SharePoint, its usage typically drops. Yet, completely discarding inactive data proves challenging as it holds vital significance for business records and compliance. Without an efficient archiving solution, organizations struggle with overwhelming data volumes, soaring storage expenses, and inefficient retrieval processes which obstruct productivity. Introducing Microsoft 365 Archive, unveiled at Ignite’23 that lets you store long-term data at a lower cost, matching its value as it ages. Let’s explore more details below!


What is Microsoft 365 Archive?

Microsoft 365 Archive is based on Microsoft Syntex and is available as a pay-as-you-go service like SharePoint Premium and Microsoft 365 Backup. It provides long-term storage for inactive aging content in SharePoint such as SharePoint sites. It is cost-effective, fast, and highly secure. The best part? With Microsoft 365 Archive, administrators have the option of reactivation of archived data after 7 days.

This process involves transferring the site and its content from the archived (cold tier) storage to the SharePoint tenant (standard) storage. While in this colder tier, the site becomes inaccessible to everyone in the organization except through Microsoft Purview or admin search.

Note: The initial release of Microsoft 365 Archive will provide site-level archiving; file-level archiving will be coming in the second half of 2024 with powerful retention policy workflow integrations.

Now, let’s talk about what Microsoft 365 Archive offers specifically for SharePoint and explore the step-by-step process to configure site archiving within SharePoint.

2. Archive In Place Content in SharePoint

When your SharePoint Online storage nears its limit, the typical solution involves purchasing additional storage regardless of the content’s activity. Microsoft 365 Archive offers a cold storage tier that securely retains inactive or older data within SharePoint at a cost-effective rate, aligning with the data’s lifecycle stage. With its built-in workflows, Microsoft 365 Archive helps site owners confirm if a site is active, inactive, or ready for deletion before moving it to the archive.

The primary benefit of moving sites to an archived state is that the storage they use no longer counts against the SharePoint storage quota.

Archiving a site in SharePoint archives everything within it, including document libraries, files, lists, and list data.
