Data Verification Considerations for NetApp NAS Client
Support Information - Storage Policy Copy
The software typically protects/archives data on various types of media. Once these operations have been performed, there is no way to ascertain if the data is valid for recovering until a data recovery operation has been performed on that data.
During a data verification operation, data is checked to see that it is valid for recovering and for being successfully copied during an auxiliary copy operation. You can verify data on all copies, or on a specific copy, and in parallel streams. A specific data protection/archive operation can also be verified on a copy. It is also possible to define a time interval of how long data verification for a data protection job is valid for a storage policy copy.
|When auxiliary copy, data verification, and content indexing operations are initiated, they will all utilize the same single auxiliary copy manager process, thus reducing the load resources on the CommServe computer.|
You can configure a copy for data verification so that
all, full, or those data protection/archive operations occurring on or after a certain date will be verified during
a data verification operation. A copy can be configured for data verification
from the Advanced tab.
Note that data verification is not set by default for any agents.
You can select individual jobs to be verified during a data verification operation from the Jobs for Copy window. You can verify jobs on all types of storage policies. The example below is for an iDataAgent Backup storage policy.
The following table describes the data verification status that is displayed in the Data Verification Status column:
|Not Picked||A job has not been picked for a data verification operation.|
|Picked for Verification||A job has been picked for a data verification operation.|
|Successful||A data verification operation ran and successfully verified this job.|
|Failed||A data verification operation ran and failed to verify this job.|
|Partial||A data verification operation ran and has not yet completed verifying this job.|
|Once a job is picked, its status in the Data Verification Status field is displayed as Picked for Verification.|
|Once a data verification operation is run, the date and time of the operation is displayed in the Date and Time of Last Verification column.|
|If this copy has already been configured for data verification, then individual backups do not have to be selected on the copy.|
|The operation can then be performed from the Data Verification dialog box.|
|More advanced options are available from the Advanced Options for Data Verification dialog box, in which you can identify the media in which data should be verified.|
In addition to verifying data which has been backed up using NRS, data which has been backed up to a library attached to a NetApp file server can also be verified to ensure that it is valid for recovery.
Three Windows registry keys are provided which allow you to redirect NetApp NAS NDMP data verification operations:
Note that this can be a large amount of data. If you choose to turn this option on, it is recommended you increase the log file size.
For more information on these registry keys, see Registry Keys and Parameters.
