Retention Policy in Office 365 Backup

A data retention policy is an agreement on retaining data for operational or regulatory compliance needs.

If user data is modified or deleted during the retention period, a copy of the original content can be always found in the backup storage.

Objects in backup storage which retention period has expired, are deleted automatically, according to a retention policy settings, so this keeps the backup storage size under control. The duration of data retention policy can be ranged from days to years.

Retention policy run automatically once a day.
