SaaS backup
Also known as Microsoft 365 backup
Independent backup of data held in cloud applications such as Microsoft 365, Google Workspace, or Salesforce.
Providers protect their infrastructure, not your data from you. Microsoft replicates your mailbox across datacentres, which protects against their hardware failing, not against a user deleting a folder or ransomware encrypting synced files.
Native retention and recycle bins have limited windows measured in days or weeks. Once that passes the data is gone, and this is the single most common gap in otherwise well-run backup programmes.
Where this comes up
SaaS backup sits inside our backup and disaster recovery work. If you are trying to work out what this means for your own environment rather than in the abstract, that is the page worth reading next, and a short call will get you a straight answer faster than either.
