Restore Troubleshooting - Exchange Public Folder Agent

Restore a deleted Public Folder from a user's mailbox

In situations where a Public Folder created in a user’s mailbox (not the Administrator’s mailbox) is backed up and then deleted before it’s restored, the user will not see the folder after the restore due to a change in ownership. For security reasons, the system assigns the ownership of the restored folder to the Administrator. Therefore, the user will not see the restored folder unless the Administrator changes the permission back to the user. The Event Viewer will issue the following message to notify you of this condition:

"Warning: Please manually set folder [...] permission."

If you want the user to be able to view that folder after the restore, which would normally be the case, then the Administrator must manually set the folder permission back to the ownership of the user.

Completed with one or more errors

Restore jobs from Exchange Public Folder iDataAgent will be displayed as "Completed w/ one or more errors" in the Job History in the following cases:

  • During restore if few folders cannot be restored and remaining folders are restored successfully, then the restore job is said to be Completed w/ one or more Errors. Reasons can be that the restore process was unable to get the folder hierarchy or some of the messages were not restored due to MAPI errors.

Recovering data associated with deleted clients and storage policies

Symptom

In a disaster recovery scenario, use the following procedure to recover 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 that 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 that 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 is used temporarily to build a CommServe.
Recovering Deleted Data
  1. Locate the latest Disaster Recovery Backup that contains the information on the entity (storage policy, client, agent, backup set or instance) you are trying to restore.
    • 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.
      • If you do not have an appropriate report, and know the media that contains the DR Backup, catalog the media using Media Explorer. Once the cataloging process is completed, details of the data available in the media are displayed.
  2. On a standby computer, install the CommServe software. For more information on installing the CommServe, see Install the CommServe.
  3. Restore the CommServe database using the CommServe Disaster Recovery Tool from the Disaster Recovery Backup described in Step 1. (See CommServe Disaster Recovery Tool for step-by-step instructions.)
  4. Verify and ensure that the NetApp Client Event Manager NetApp 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 brings back the entity in the CommServe database and the entity is visible in the CommCell Browser. (Press F5 to refresh the CommCell Browser if the entity is not displayed after a successful merge.)

  8. You can now browse and restore the data from the appropriate entity.

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