Continuous Data Protection (CDP) backup scheme allows reverting the protected data to any point in time.
Follow these steps to troubleshoot CDP Backup Failure:
- Get familiar with technology of CDP Backup in the About part.
- Follow to Troubleshooting part to troubleshoot and resolve the issue.
About CDP
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 & Transaction log Backups, you can select any point in time to revert the Exchange data to.
Continuous Data Protection (CDP) allows reverting the protected data to any point in time.
In Acronis Backup, CDP is a backup scheme applicable to:
- MS Exchange Information Stores;
- Storage Groups;
- Databases.
Continuous Data Protection (CDP) scheme
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.
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.
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.
Backup type, validation
To access these settings, click Show backup type, 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 methodcheck box.
(!) Note: To back up transaction log files, circular logging must be disabled in Exchange. Otherwise, the backup task will fail.
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.
Troubleshooting
Follow step-by-step instructions below to troubleshoot the issue.
1. Try to create the Information Store backup of Exchange Database without CDP Backup option. If this works fine - go to Step 2). Should Information Store backup fail as well, proceed as described in Acronis Backup Advanced for Exchange: Troubleshooting Information Store Backup Failures.
2. Collect the following information:
- Export of the backup plan (right-click on the backup plan -> Export);
- Log of the failing backup;
On the Agent machine, collect System Report as described in Acronis Backup 11.7/11.5 Generating System Report, if this fails for any reason, you can use this AcronisInfo Utility tool.
3. When all the information is collected, contact Acronis Support.
