This page provides a guide to configuring a NetApp SnapLock storage as a Storage Target in Verba.
SnapLock is an alternative to the traditional optical "write once, read many" (WORM) data. SnapLock is used for the storage of read-only WORM data. SnapLock is a license-based, disk-based, open-protocol feature that works with application software to administer non-rewritable storage of data. The primary objective of this Data ONTAP feature is to provide storage-enforced WORM and retention functionality by using open file protocols such as CIFS. SnapLock can be deployed for protecting data in strict regulatory environments in such a way that even the storage administrator is considered an untrusted party. SnapLock provides special purpose volumes in which files can be stored and committed to a nonerasable, non-rewritable state either forever or for a designated retention period. SnapLock allows this retention to be performed at the granularity of individual files through standard open file protocols such as CIFS.
For a general description of storage targets, please refer to Storage and export targets.
Please refer to the official NetApp SnapLock guide to deploy and configure the NetApp system.
Verba uses the NetApp Manageability SDK to access the WORM specific features of the Data ONTAP API.
NetApp SnapLock permissions
The system requires permission for the following Data ONTAP API calls:
- 7-mode (pre 9.0):
- cluster mode (9.x or earlier with cluster mode enabled):
The system uses standard SMB protocol for file operations. The following permissions must be enabled:
NetApp SnapLock compliance clock
When Verba uploads / moves media files to a NetApp SnapLock storage target, setting the retention period with auto-delete it takes the clock drift of SnapLock into account at the point of the file move. If the storage goes down at any time during the retention period (between the upload / move and the date of auto-deletion) Verba will not be able to retrieve that information, thus will try to delete the files in question earlier than SnapLock would allow it. As a result, auto-deletion by Verba policies might fail.
Creating a NetApp SnapLock target
Follow the steps below to create a new Verba Storage target for NetApp SnapLock:
Step 1 - Open the Verba Web interface then select Data Management > Storage targets from the top menu.
Step 2 - Click on Add New Storage Target
Step 3 - Fill out the configuration form according to the requirements in the following table.
|Name||Name your storage target. This name will identify this target across the system.|
|Type||Select NetApp SnapLock|
|Path||Specify the path where the storage is accessible in the Windows file system (UNC path)|
|Volume Path||Specify the NetApp specific volume path|
|Host Name or IP Address|
The connection string used by the application to connect to the NetApp SnapLock REST API.
Depending on the version of the NetApp SnapLock system, 7-mode or cluster mode can be configured.
For 7-mode NetApp SnapLock systems:
For cluster mode, further parameters are needed which can be advertised in the Host Name or IP Address field:
The parameters should be concatenated either with ; or ,
The parameters can be determined from NetApp console with the following commands:
The IP address of the server is 10.2.1.13
Then hostname fields value is:
|Port||The access port of the NetApp SnapLock REST API (443 by default)|
|API User||User name of the API user configured for Verba access in NetApp SnapLock|
|API Password||Password of the API user configured for Verba access in NetApp SnapLock|
|Use custom credentials for accessing the file share|
It is possible to use credentials other than the service user for each NetApp SnapLock storage. Provide the username and password credentials for accessing the storage through SMB.
Step 4 - Click Save to save the settings
After this point, the Storage target is available for use by other Verba components (e.g. Data management policies).
Configuring SSL certificates for the SnapLock REST API connection
NetApp SnapLock can be configured to accept SSL connections from trusted sources only. You can configure the trusted and signed certificates used by the Verba system on the servers directly. If you intend to use multiple NetApp SnapLock systems for Verba, you need to use the same certificates for all, because it is a server-side setting in the Verba system. By default, Verba uses its own self-signed certificates for the SSL connection.
Follow the steps below to configure the certificates.
Step 1 - Copy the X.509 certificate and key files to the Verba server
Step 2 - Navigate to the Configuration / Servers
Step 3 - Click on the Verba server you would like to configure
Step 4 - Click on the Change Configuration Settings tab
Step 5 - Open the Storage Management / Upload Targets / NetApp SnapLock tree on a Verba Recording Server or the Storage Management / Storage Targets / NetApp SnapLock tree on a Verba Media Repository server or on a Verba Media Repository and Recording Server
Step 6 - Configure a trusted custom X.509 certificate for the connection
Step 7 - Click the Save icon and follow the instructions on the page to apply the configuration on the server
Step 8 - Repeat the steps above on all Verba servers where you move files to NetApp SnapLock
