Restore - Documentum iDataAgent (Oracle)

Overview

As restoring your backup data is very crucial, it is recommended that you perform a simple restore operation immediately after your first full backup to understand the process. The following sections explains the steps for performing simple browse and restore operations.

Prior to running your first restore operation, ensure the following:

  • Verify that the CommServe, MediaAgent and media library are powered on.

  • You have successfully done a backup of the data to be restored.

  • Verify that the media from which you wish to perform the restore is available in the CommCell. Use the List Media feature to identify the media required by the restore operation.

  • Always ensure that sufficient space has been allocated for the restore.

Restores can be run on-demand or can be scheduled to be run at a later point of time.

Your First Restore

The restore operation can be done using one of the following methods:

  • File-level Browse and Restore, which is useful when you want to restore documents.

  • Component-level Browse and Restore, when you want to restore components of a Documentum Repository (database, storage area, or full-text indexes).

For this first simple restore, let us perform an in-place restore of documents and components of a Documentum Repository.

From the CommCell Browser, select one of the following two methods: Documentum File Browse and Restore or Component Level Browse and Restore. These two methods are are described below.

Documentum File Browse and Restore

This type of Browse and Restore is geared towards end-users and illustrates performing a basic browse and restore of documents. To browse and restore documents:

  1. From the CommCell Browser:

    • Navigate to Client Computers | <Client> | Documentum.

    • Right-click the <Instance>, point to All Tasks, and then click Browse and Restore.

    commcell_browser

  2. Select the Documentum View check box and specify a subclient (for example, default) that contains documents.

    Click View Content.

  3. In the right pane of the Browse window, click the <Instance> and select all the entities.

    Click Recover All Selected.

    restore_selected

  4. From the Restore Options for All Selected Items dialog box, specify the following:

    1. Select the name of the source client computer in the Destination Client from the list.

    2. By default Restore to same folder check box is selected to perform an in-place restore.

      • Clear the Restore to same folder check box and type the path in Specify Documentum Destination Folder Path for an out-of-place restore.

    3. Select Create Entities in Repository check box to check the documents into the Documentum Repository.

    4. In Specify Destination Path for Storage Area Files, enter the file system path on the destination computer to which the files will be restored. Typically, this would be a system path on the Primary Content Server. Click one of the following:

      • Current Active Version to check the file in with the same version number that is currently active in Documentum.

      • Next Minor Version to check the restored file to the next minor Version. For example, if the restored document was a minor version (such as, 1.2), it will be check it into the next minor version (such as, 1.3). If the restored document was a major version (such as, 2.0), it will be checked into the next minor version (such as, 2.1).

      • Next Major Version to check-in the file to the next major version. For example, if the restored document was a major version (such as, 2.0), it will check it into the next major version (such as, 3.0). If the restored document was a minor version (such as, 1.2), it will check it into the next major version (such as, 2.0).

    5. In When Storage Area File Exists pane, select one of the following:

      • By default, Skip is selected to specify that if an item is selected for restore and that item already exists, it will not be restored.

      • Select Unconditional Overwrite to specify if the restored data is to be unconditionally written to the specified location.

    6. Select Impersonate User check box and type the username, password and confirm password to specify the Oracle User account used by the system to perform restore operations for this instance.

    7. Click OK.

  5. Click the Job Initiation tab.

    Select Immediate to run the job immediately.

    Click OK.

Component-Level Browse and Restore

This type of Browse and Restore is geared towards administrators and illustrates performing a basic browse and restore of all components of a Documentum Repository (database, storage area, or full-text indexes):

Note

To ensure consistent restores, it is recommended to shutdown the Documentum Repository and the database in an appropriate mode before restoring.

  1. From the CommCell Browser:

    • Navigate to Client Computers | <Client> | Documentum.

    • Right-click the <Instance>, point to All Tasks, and then click Browse and Restore.

  2. Click View Content.

  3. Expand the Documentum and select the components such as Storage Area, Full-Text Index and Database to be restored.

    For the first restore job, select any folder with smaller data size.

    Click Recover All Selected.

  4. By default, Overwrite Files and Overwrite if file on media is newer is selected to overwrite all backed up storage areas.

    By default, Restore to same folder is selected to restore the storage area to the same folder.

  5. Click the Database tab.

    • Select the name of the client computer in the Destination Client from the list.

    • Clear NO CATALOG check box to specify a Catalog Connect string.

    • You can use the three blank fields to enter the connect string for the catalog database. Use the first field to type the recovery catalog database user ID. Use the second field to type the password for the user ID, and use the third field to type the recovery catalog service name.

    • Select Restore Data check box to restore the database.
