Show Aged Data During Browse and Recovery

Required Capability: Capabilities and Permitted Actions

To show aged data during browse and recovery operations from the CommCell Console:

1. Right-click the CommServe in the CommCell Browser window, click Control Panel, and then click Browse/Recovery.
2. Check the Show Data Aged During Browse and Recovery option.
3. Click OK.
4. Run Browse operations to view the aged data.

Recovering Data Associated with Deleted Clients and Storage Policies

The following procedure describes the steps involved in recovering data associated with the following entities:

• Deleted Storage Policy
• Deleted Client, Agent, Backup Set or Instance

Before you Begin

This procedure can be performed when the following are available:

• You have a Disaster Recovery Backup which contains information on the entity that you are trying to restore. For example, if you wish to recover a storage policy (and the data associated with the storage policy) that was accidentally deleted, you must have a copy of the disaster recovery backup which was performed before deleting the storage policy.
• Media containing the data you wish to recover is available and not overwritten.
• If a CommCell Migration license was available in the CommServe when the disaster recovery backup was performed, no additional licenses are required. If not, obtain the following licenses:
  • IP Address Change license
  • CommCell Migration license

  See License Administration for more details.

• A standby computer, which will be used temporarily to build a CommServe.

Recovering Deleted Data

1. Locate the latest Disaster Recovery Backup which contains the information on the entity (Storage Policy, Client, Agent, Backup Set or Instance) that you are trying to restore.
   • You can check the Phase 1 destination for the DR Set or use Restore by Jobs for CommServe DR Data to restore the data.
   • If the job was pruned and you know the media containing the Disaster Recovery Backup, you can move the media in the Overwrite Protect Media Pool. See Accessing Aged Data for more information. You can then restore the appropriate DR Set associated with the job as described in Restore by Jobs for CommServe DR Data.
   • If the job is pruned and you do not know the media containing the Disaster Recovery Backup, you can do one of the following:

     If you regularly run and have copies of the Data on Media and Aging Forecast report you can check them to see if the appropriate media is available.

2. On a standby computer, install the CommServe software. For more information on installing the CommServe, see CommServe Deployment.
3. Restore the CommServe database using the CommServe Disaster Recovery Tool from the Disaster Recovery Backup described in Step 1. (See Restore a Disaster Recovery Backup for step-by-step instructions.)
4. Verify and ensure that the Bull Calypso Client Event Manager Bull Calypso Communications Service (EvMgrS) is running.
5. If you did not have a CommCell Migration license available in the CommServe when the disaster recovery backup was performed, apply the IP Address Change license and the CommCell Migration license on the standby CommServe. See Activate Licenses for step-by-step instructions.
6. Export the data associated with the affected clients from the standby CommServe as described in Export Data from the Source CommCell.

   When you start the Command Line Interface to capture data, use the name of the standby CommServe in the -commcell argument.

7. Import the exported data to the main CommServe as described in Import Data on the Destination CommCell.

   This will bring back the entity in the CommServe database and the entity will now be visible in the CommCell Browser. (Press F5 to refresh the CommCell Browser if the entity is not displayed after a successful merge.)

8. If you have additional data that was backed up after the disaster recovery backup and before the deletion of the entity, use the procedure described in Import Metadata from a Tape or Optical Media to obtain the necessary information.
9. You can now browse and restore the data from the appropriate entity.

   As a precaution, mark media (tape and optical media) associated with the source CommCell as READ ONLY before performing a data recovery operation in the destination CommCell.

Import Metadata from a Tape or Optical Media

The following procedure describes the steps for importing metadata from a removable media.

Before You Begin
The following procedure must be performed using the Windows Media Explorer. If the required media is available on a library attached to a Unix or NetWare computer, move the media to a library attached to a Windows computer with the Media Explorer software and then perform this operation.
To import metadata from a tape or optical media
1.	Open Media Explorer by running the following program: <Media Explorer install folder>\MediaExplorer.exe
2.	Catalog the appropriate media as described in Cataloging Media Procedure.
3.	Once the media is catalogued, you can export the information using the Generate Metadata option. Click Generate Metadata to generate metadata information from a backup media and use the metadata to merge the backup data back into the CommCell. Select the Version to which you want to generate the output and click OK.
4.	Select the location to generate the metadata and click OK.
5.	Click OK in the Media Explorer prompt which is displayed when the metadata is successfully generated.
6.	The metadata information can be located in the Metadata For Import folder within the specified location.
7.	If the computer in which the metadata is generated is different from the CommServe computer, copy the Metadata For Import folder to the CommServe computer.
8.	Locate the CommCellInfo_DR_Tool_capture.CAB and unzip its contents from the zip file. This will create the CommCellInfo_DR_Tool_capture folder.
9.	Run the following command from the command prompt: <software installation path>/Base/CommCellMigration -convert -<mediafilesdir> Where: <mediafilesdir> is the directory in which the source files (captured in Step 6) are located. convert is the option to create a SQL dump file (CommServ_Convert.dmp) in the current directory. This file can be used as an input to the merge command to merge the information in this database to the main database.
10.	Merge the captured data to the main CommServe using the following command from the command prompt: <software installation path>/Base/CommCellMigration -merge [ | -tapeImport] [-restorefile ] -path [-pathUser -pathPassword ] [-Consumelicense] [-setTapeReusable] Where: restorefile  is the SQL dump file name (CommServ_Convert.dmp) path is the software installation path>/Base path pathUser, pathhPasword is the user name and password to login to the CommServe. This option is not necessary if you have already executed the qlogin command. For example, you can use the following command to import the data captured from media using Media Explorer from the same CommCell: CommCellMigration -merge -tapeImport -restorefile CommServ_Convert.dmp -path <software_install_folder>\Base
