Enhanced soft delete improves upon Azure Backup's existing soft delete capability to provide the ability to recover your backup data in scenarios of accidental or malicious deletion. With enhanced soft delete, you get the ability to make soft delete irreversible, which protects soft delete from being disabled by any malicious actors. Hence, enhanced soft delete provides better protection for your backups against various threats. Enhanced soft delete also allows you to provide a customizable soft delete retention period for which soft deleted data must be retained.
Enhanced soft delete is now in preview for recovery services vaults as well as Backup vaults in selected regions, and will be available in other regions in the following weeks.
Please refer to the documentation for more details.
