Home > Data Protection > PowerProtect Data Manager > PowerProtect Data Manager: Microsoft Exchange Backup and Recovery > Perform disaster recovery from the Data Domain Cloud Tier
The Microsoft application agent provides a command-line tool to complete disaster recovery of save sets that are in a Data Domain Cloud Tier. After an MTree is recovered according to the disaster recovery procedure, you must restore the backup indexes from the Data Domain Cloud Tier.
When the Microsoft application agent moves a backup to the cloud, the index files are maintained on the active tier. A copy of the index files is created and moved to the cloud tier for long-term retention.
After an MTree is restored during a disaster recovery, all the files that resided only on the active tier are lost and unavailable. Only the files that were moved to the cloud are available. In this case, you must run msagentadmin administration with the --dr-recall parameter to restore the indexes.
After the indexes are recalled to the active tier, the data save sets for the same time range are also recalled unless you type n when prompted and browse to the recall of the found save sets [y/n]. If you choose to not recall the save sets, you can manually recall the save sets later.
Use the msagentadmin administration command with the following syntax to recall the indexes to the active tier:
msagentadmin.exe administration --dr-recall --ddhost "<Data_Domain_server_name>" --ddpath
"<name_and_path_of_storage_unit>" --dduser "<DDBoost_username>" --appID <application_ID>
Consider the following example commands to perform disaster recovery of Exchange Server with data on a PowerProtect DD Series Appliance Cloud.
