Continuous Data Protection (CDP) allows reverting the Exchange data to almost any custom point in time. With the CDP scheme, transaction log files are backed up automatically as soon as they are closed by Exchange. You only specify when to perform full database backups. The transaction log file backup is paused until the full backup is completed.
To set up the CDP backup scheme, specify the appropriate settings as follows.
Schedule
Set up when and how often to perform full database backups. To learn more about setting up the schedule, see the "Scheduling" section of the product help system or guides for Acronis Backup & Recovery 11.5.
Retention rules
[Optional] Specify how long to store backups in the location and whether to move or delete them afterward. The retention rules in this scheme are applied after creating a full backup. The Keep backup indefinitely is set by default. This means that no full backups will be deleted automatically. For more information about retention rules, see the "Setting up retention of backups" section of the product help system or guides for Acronis Backup & Recovery 11.5.
Backup type, 2nd location, validation
To access these settings, click Show backup type, 2nd location, validation.
Backup type
[Optional] The archive will contain a number of full and transaction log backups.
If a deduplicating vault is selected as a backup destination, full backups can be obtained by backing up only the changes that have occurred since the last full backup. To do this, select the Create full backups using the Express full backup method check box. For more information on express backups, see "Express full backup method".
Note: To back up transaction log files, circular logging must be disabled in Exchange. Otherwise, the backup task will fail.
2nd location
[Optional] Specify whether to replicate backups to another location. The replication in this scheme is performed after creating a full backup. Thus, transaction log backups are replicated to another location after the next full backup is created. For more information about backup replication, see the "Setting up replication of backups" section of the product help system or guides for Acronis Backup & Recovery 11.5.
When to validate
[Optional] Define when to perform validation.
Disabling CDP
The CDP scheme is a combination of scheduled full backup activities and always running transaction log backup activity. You may need to temporarily disable CDP when performing database maintenance operations. To do this, navigate to the Backup plans and tasks view, select the backup plan that use the CDP scheme, and click Disable. Once the maintenance operations are completed, enable the backup plan.
