Continuous Data Protection (CDP) allows reverting the Exchange data to almost any custom point in time.
In Acronis Backup, CDP is a backup scheme applicable to Microsoft Exchange information stores, storage groups, and databases. In this scheme, you specify when to perform full backups. In addition, the transaction log files are backed up automatically as soon as they are closed by Exchange. Having both full backups and transaction log backups, you can select almost any custom point in time to revert the Exchange data to.
