Retain recent backups

If you create full backups on a daily basis as recommended earlier in this document, you should configure a backup retention policy to maintain the backups created in the last two weeks (14 last backups for each domain controller). This approach will provide you with a sufficient number of backups to recover from an Active Directory failure that remained undetected for some time. For information on how to configure a backup retention policy, refer to the User Guide supplied with this release of Recovery Manager for Active Directory.

In addition to the retained backups, you can also archive at least one domain controller backup on a weekly basis. This will allow you to retrieve Active Directory data (for instance, deleted objects) from a period past the recent backup history you retain. Make sure that these archived backups cover the entire tombstone lifetime period (180 days by default).

The best practice is to create BMR backups only once a week to minimize the required storage space.

For information on how to configure a backup retention policy for a Secure Storage server, refer to Secure Storage server backups.

For security reasons, keep at least one copy of each backup off-site in a properly controlled environment in order to protect it from possible attacks by malicious individuals via the network.

 

Where to store backups

For each Computer Collection, you can specify where to store the Collection’s backup files. You can store backups on the computer running Recovery Manager for Active Directory, the domain controller being backed up, or any available network share.

This section provides general recommendations where to store backups to be used in specific restore scenarios, such as granular online restore of directory objects, complete offline restore of Active Directory, or Active Directory forest recovery.

For more information on how to specify backup storage settings, see the User Guide supplied with this release of Recovery Manager for Active Directory.

 

Storing backups for granular online or complete offline restores

The following diagram shows the recommended method for storing the backups you plan to use for granular online restores of directory data or complete offline restores of Active Directory:

Figure: Backups for Granular Online or Complete Offline Restores

It is recommended that you store such backups in a central backup storage accessible to the Recovery Manager Console via a fast and reliable link. Such a link is required because during a restore operation backup files may be copied or unpacked from the central backup storage to the computer where you are using the Recovery Manager Console.

 

Storing backups for forest recovery

The following diagram shows the recommended method for storing the backups you plan to use for forest recovery operations:

Resources/Images/3_DG.png

Figure: Backups for Forest Recovery

If you intend to use Recovery Manager for Active Directory to recover the entire Active Directory forest or specific domains in the forest, it is recommended that you store each backup file on the domain controller being backed up. This will considerably decrease the network utilization during backup operations and speed up the recovery process. On top of that, storing backup files on target domain controllers simplifies the permissions required to access those files.

Bare Metal Recovery backups

  • For BMR backups, the best practice in an enterprise environment is to deploy a dedicated backup server performing the role of an SMB repository with enough memory and CPU to cope with the amount of backup data. You need to specify custom access credentials for the share to access the backup data even when Active Directory is unavailable.

  • You should store backups in the repository that is located in the same Active Directory site.

  • For Windows Server 2008 R2, BMR backups that are stored on the same Forest Recovery Console host are not supported.
