Microsoft has announced that they will deliver Microsoft 365 Backup for Exchange, SharePoint, and OneDrive in public preview in late 2023. Microsoft has several advantages when it comes to access to data and ability to update APIs, but it also has to cope with the putting all eggs in one basket syndrome. We don’t know how Microsoft will charge for Microsoft 365 backup, but it’s likely to be on a consumption basis.
Backup vendors say you should definitely use their products to protect your valuable Microsoft 365 data. Backup products can do a good job, but the nature of Microsoft 365 creates many challenges at a technical level. A lack of APIs is the most fundamental issue, but the connected nature of Microsoft 365 apps is another.
