We've released retention policies for 365 Total Backup.
With this new feature, admins can now create and apply retention policies to their backups, ensuring that critical data is kept for the appropriate length of time and that backups are automatically deleted when they are no longer needed. Retention policies can be customized to suit the specific needs of each organization. With this level of control, users can ensure that their backups remain compliant with industry regulations and organizational policies.
