Recover a File from a Unix Terminal Window

Before You Begin:

• Review Recover a File from a Unix Terminal Window.
• Review the general recovery requirements from What You Need to Know Before Performing a Recovery and any agent-specific recovery requirements from Recovery Considerations for these Agents prior to performing any recovery.

Required Capability: See Capabilities and Permitted Actions

To perform a non-browse recovery of a file from a Unix terminal or console window:

1. Log on to the client computer.
2. Open a Terminal or Console Window.
3. Perform an action that executes an open and read on an archived file to initiate the recovery operation. For example, you can use the vi or cat commands to do this:
   • vi <path><filename>
   • cat <path><filename>
4. The recovery job is submitted to the Job Controller, and you can track the status of the job from the Job Controller window in the CommCell Console.

Set Stub Recovery Parameters

Before You Begin

• Review information about Recall Throttling before beginning this procedure.

Required Capability: See Capabilities and Permitted Actions

To set stub recovery parameters:

1. From the CommCell Browser, right-click the appropriate agent icon and then click Properties.
2. From the General tab of the Agent Properties dialog box, click the Stub Recovery Parameters option.
3. Select the appropriate value for the Maximum Stub Recovery field.

4. Select the appropriate value for the Time between recall to count as successive in seconds field.

5. Select the appropriate value for the Time to wait after maximum successive recalls limit is reached in seconds field.
6. Click OK, then either wait 5 minutes for the change to take effect or restart the GXHSM service for it to take effect immediately.

Restore Out-of-Place, Cross-Platform or Cross-Application

Before You Begin

• Review the general and agent-specific restore requirements accessed from Restore Backup Data prior to performing any restore operation.

Required Capability: See Capabilities and Permitted Actions

To browse and restore data:

1. Begin any restore procedure. See Basic Restore or Browse and Restore for step-by-step instructions.
2. From the agent's Restore Options dialog box, select the restore destination:
   • Destination Computer - By default, data is restored to the same computer from which it was backed up. To change the destination computer, select one from the list. The list includes established clients within the CommCell, with Operating Systems that support the out-of-place, cross-platform, or cross-application restore operation from this client.
   • Restore to Same Paths - Specifies whether the restore operation must restore data to the Destination Computer using the same path from which it was backed up. Clear this option if you want to restore to a different path and activate the Destination folder box.
   • Destination Folder - Use this space to enter (or browse to) the path on the destination computer to which the data must be restored. If the specified path does not exist, it will be created during the restore process.

     On Windows computers, the UNC path of a shared drive can be specified. (e.g., \\servername\sharename\directory). Deselect Restore to Same Paths and then type the UNC path of the shared drive in the Destination Folder field.

3. After completing your selections, continue with the restore procedure.

Recover Out-of-Place or Cross-Platform

Before You Begin

• Review the general and agent-specific recovery requirements accessed from Recover Archived Data prior to performing any recovery operation.

Required Capability: See Capabilities and Permitted Actions

To browse and recover data:

1. Begin a browse and recovery procedure from the CommCell Console. See Recover a File from the CommCell Console for step-by-step instructions.
2. From the agent's Recover Options dialog box, select the recovery destination:
   • Destination Computer - By default, data is recovered to the same computer from which it was archived. To change the destination computer, select one from the list. The list includes established clients within the CommCell, with Operating Systems that support the out-of-place or cross-platform recovery operation from this client.
   • Recover to Same Paths - Specifies whether the recovery operation must recover data to the Destination Computer using the same path from which it was archived. Clear this option if you want to recover to a different path and activate the Destination folder box.
   • Destination Folder - Use this space to enter (or browse to) the path on the destination computer to which the data must be recovered. If the specified path does not exist, it will be created during the recovery process.

     On Windows computers, the UNC path of a shared drive can be specified. (e.g., \\servername\sharename\directory). Deselect Recover to Same Paths and then type the UNC path of the shared drive in the Destination Folder field.

3. After completing your selections, continue with the recovery procedure.

Restore to a Network Drive/NFS-Mounted File System

Before You Begin:

• On Windows computers, shared network drives exist as Windows share directories (i.e., shares) on some other computer on the network. For data security reasons, these shares possess access privileges that determine who can access the share and the rights under which access is permitted. If your Windows account does not have privileges to write data to the share, you must be prepared to provide the login and password of a Windows account that does have these privileges.
• For Unix computers, ensure that the destination computer has root permissions for the NFS-mounted file system. If the destination computer does not have these permissions, restores will fail.
• Ensure that the network drive / mounted file system to which you intend to restore the data is accessible as a mapped network drive/ NFS-mounted file system from the destination computer.
• Review the general and agent-specific restore requirements accessed from Restore Backup Data prior to performing any restore operation.

Required Capability: See Capabilities and Permitted Actions

To browse and restore data using wildcards:

1. Begin any restore procedure. See Basic Restore or Browse and Restore for step-by-step instructions.
2. From the Restore Options dialog box, ensure that the Destination Computer is the source computer from which the shared drive was backed up, not the computer that has the share. If the data did not originate from the shared drive, de-select Restore to Same Paths and then type the UNC path of the shared drive in the Destination Folder field (e.g., \\servername\sharename\directory).
3. To restore to a Windows computer, click Advanced.

   If you do not have Change permissions for the share to which you intend to restore the data, then you must select Impersonate NT User in the Advanced Restore Options dialog box and provide the login and password of a Windows account that does have these permissions. (Otherwise, the data cannot be restored to the selected share. Ordinarily, if you can copy or create a file in the share, you should be able to restore data to that share without having to select this option.)

   If the user account is established as a domain user account, you must enter a fully qualified user name (e.g., <domain_name>\<user_name>) and password.

4. Optionally select the additional restore options that you want to use from the Advanced Restore Options dialog box.
5. Click OK.
6. Optionally select the additional restore options that you want to use from the Restore Options dialog box.
7. Click OK.
8. After completing your selections, you can either start an immediate restore or schedule the restore.
   • If you want to schedule the job, click the Job Initiation tab from the Restore Options dialog box, click Schedule, and enter your selections in the Schedule Details (Schedule Details) dialog box. Clicking OK from this dialog box saves your schedule. See Scheduled Data Recovery Operations for an overview of this feature.
   • If you want to run the job now, accept or click Run Immediately in the same tab and then click OK.

   While the job is running, you can right-click the job in the Job Controller and select Detail to view information on the job.

NOTES

• The restored data assumes the access characteristics of the destination share.
• In the case of a File Level restore using the Image-Level iDataAgent, the restored data assumes the access characteristics of the destination share.
