The Getting Started - VMware Backup documentation provides all the steps necessary to immediate run your first backup and restore.
Automatic Disk Group Configuration tool manages disk group configuration for the appliance when the appliance is operating in the automatic disk configuration mode. During the initial disk configuration, virtual disks (LUNS) are created from the available disks within the optional external storage enclosures. The virtual disks are created from a group of physical disks consisting of a set of seven disks, slots 1 through 7 or 8 through 14. Each virtual disk is created with a default size of 1.5 TB. If the required amount of space is not available in the disk group, then it uses the available disk space. If more than one external storage enclosure is available, then it configures all the available disk groups and creates virtual disks on all the disks. The virtual disks are created with RAID-5.
The disks in slot 0 (if any) are assigned as a global hot spare. All virtual disks are formatted with NTFS volume and use a file allocation unit size of 64 KB. The volumes are mounted under C:\DiskStorage directory as Mount Points. The software then automatically configures one disk library containing all of the external virtual disks. A default storage policy is created using this disk library for backup operations.
The automatic disk group configuration configures disk library, creates a
deduplication storage policy using this disk library for backup operations and
non-deduplication storage policy for DDB backup. Once deduplication storage
policy is created, DDB Backup subclient is automatically created under the
MediaAgent client computer and is automatically configured to use the
non-deduplication storage policy. This deduplication database backup job is automatically scheduled for every 8 hours. |
For Value Configuration:
One RAID 10 LUN for deduplication database using disk from 0-5 slots
One RAID 6 LUN for disk library using disk from 6-11 slots
One RAID 6 LUN for additional disk library using disk from 0-11 slots
For Enterprise Configuration:
Two RAID 10 LUNs for deduplication database using disk from 0-5, 6-11 slots.
One RAID 6 LUN for disk library using disk from 0-11 slots
Note that the second DDB LUN can also be used for the destination copy of a DASH Copy setting for copying data from a different MediaAgent where multiple locations are managed by the same CommServe.
To access the Automatic Disk Group Configuration tool, go to Start > Programs > CommVault Systems > Automatic Disk Group Configuration.
After the initial disk configuration, the Automatic Disk Group Configuration tool will be displayed whenever there are new disks to be configured for use in the library. The Automatic Disk Group Configuration tool may display in the following scenarios:
The
Automatic Disk Group Configuration tool provides the following options:

Client agents are software modules that perform data protection and data recovery operations for specific operating systems or applications. Multiple agents may be used to protect all types of data residing on a computer. For more information on client agents and overview of the interaction between the various CommCell components, see CommCell Overview.
For more information on installing the client modules and step-by-step installation procedures, see Installation.
When you install agents in an IPv6-capable network, the agents must also be IPv6-capable. For remote installations, this setting must be enabled manually. To do so, create the nOverridePreferredIPFamily registry key on the agent computer and set the value to '0', prior to installing the software. See Internet Protocol - Important Considerations for additional IPv6 considerations.
Once the client agents are installed, backup operations are automatically scheduled. In addition to the scheduled backup other custom backup operations can also be performed.
The following backup schedules are created automatically.
Custom backups operations can be performed using the EZ Operations Wizard.
To backup data using EZ operations wizard:
For a comprehensive overview of backup operations and more backup options, see Back Up Data.
Data restore operations are performed when the production data is not available for use and the data needs to be restored from the backup storage. Backup data can be restored using the EZ Operations Wizard.
To restore data using EZ operations wizard:
See Restore Backup Data for comprehensive overview of data restore and more restore options.
Backup targets can be either magnetic libraries or tape libraries. The following sections explain the library configuration procedures.
Magnetic Libraries can be configured from the CommCell Console using Library and Drive Configuration window in the Control Panel. See Configure Devices for more information and detailed instructions.
Internal physical data disks (other than the Operating System disks) configured and shipped with the appliance are identified and used by the software. If your appliance is configured with internal data disks, the software uses the internal data disks for the following purposes.
The virtual disk consisting of the internal disks will be configured as a Magnetic Disk Library separate from the external storage enclosure Magnetic Disk Library. Note that the internal disks are not monitored for the standard/advanced state changes for the appliance.
Tape libraries must be manually configured. Use the following procedure to configure tape libraries.
To configure sighted tape libraries:
1. | Click the Backup Target button on EZ Operations Wizard. | |
If the EZ Operations Wizard is not displayed double-click the icon in the toolbar. | ||
2. | Select Tape or Optical Devices. Click Next. |
|
3. | Click and select the library that you want to configure. Click Next. |
|
4. | Enter the number
of days that you want to preserve the backup data. Click Next. |
|
5. | Review the summary information and click Finish.
You can click Back to return to the previous dialog to change any of the selections. |
|
6. | Click OK. |
Data Deduplication identifies and eliminates redundant information from the backup data, which provides significant reduction in the storage space required for data protection operations. When data is backed up for the first time, all the data is stored physically. If the same data is subsequently identified in another backup operation, then it is stored as a pointer to the previously stored copy.
The Getting Started - Deduplication to Disk documentation provides all the steps necessary to set up and use deduplication.
The deduplication store is a database that manages the deduplication process and is automatically created for all deduplication-enabled storage policy copies.
|
Backup data that is stored in the backup targets can be managed by defining rules to retain the data in the backup media. The following data retention parameters are set by default:
Use the EZ Wizard to modify the retention parameters.
Note that the EZ Wizard displays the initially configured library. If you have more than one tape libraries or magnetic libraries attached to a MediaAgent, use the CommCell Console to configure backup retention parameters for the additional libraries.
The following sections cover the procedures involved in managing PowerVault DL Backup to Disk Appliance on a day-to-day basis.
Magnetic Libraries may be moved from one MediaAgent to another MediaAgent within the same CommCell. All disk groups within a Magnetic Library must be moved together. Moving individual disk groups is not supported.
To migrate the appliance internal disk group Magnetic Library, shut down the appliance and move the internal backup data disks to the identical internal drive slots in the new MediaAgent.
To migrate the external storage enclosure Magnetic Library, shut down the appliance. Then recable all of the external storage enclosures attached to the appliance to the new MediaAgent. Alternatively, remove the physical disks of every external storage enclosure and insert in a storage enclosure on the new MediaAgent ensuring to place the physical drives in the same slot numbers.
If the libraries on the CommServe host are migrated, make sure to configure the new disaster recovery backup destination after the migration is complete. See Change the Disaster Recovery Backup Destination for more details. |
If you want to move disk libraries in the appliance from one MediaAgent to another MediaAgent, consider the following two options.
In cold migration of Magnetic Libraries, the appliance is not functional when the internal disks or external storage enclosures are migrated. Move the disk libraries as required. When the appliance is powered back, the migrated libraries are recognized in their new location.
In a hot migration of Magnetic Libraries, the appliance remains functional during the migration. When the appliance is accessed after the migration is complete, the migrated libraries are recognized in their new location.
Follow the steps given below to perform a hot swap.
Alerts inform you of conditions occurring within a CommCell. These conditions can range from minor occurrences that do not require intervention to severe occurrences that require immediate intervention.
The following alerts are automatically created to monitor and report any issues with data protection operations and associated tasks.
Alert Type | Criteria | Description |
