Overview - BlueArc File Archiver Agent
- This agent is deprecated in this release. You must transition to OnePass for Hitachi HNAS (BlueArc) and Isilon as described in Transitioning from a V9 Traditional Archiver Agent to V11 OnePass.
- New installations of this agent are not supported in this release.
- You must deconfigure this agent before you upgrade the client.
- You can perform recovery operations only with the deconfigured agent.
- You cannot perform archive jobs with this agent.
See End-of-Life, Deprecated and Extended Support - Products for information about deprecated products.
Note: If you want to continue to use the Hitachi HNAS (BlueArc) or Isilon File Archiver for archiving and recovery operations, you cannot upgrade the client.
File Archiver for BlueArc Agent is installed as a stand alone archiving agent to archive and recover data residing on a BlueArc File Server. The Data is always archived on CIFS share.
The Archived data allows preservation, transparent retrieval, and discovery of information held within file system environment. It reduces the size of data on the primary storage and decreases the duration of backup operations by the corresponding iDataAgent. Migrating data from file systems to secondary, tiered-storage maximizes storage utilization across the enterprise.
The File Archiver for BlueArc can optionally create stubs that contain information about the archived data to facilitate end-users with non-browse recovery operations from third-party applications. Migrated data can also be recovered from the CommCell Console using the browse recovery operation whether the stubbing feature is enabled or disabled. Additionally, it employs centralized, policy-based storage to reduce costs and simplify management.
The BlueArc File Archiver involves the following key features:
You can configure the stub recovery parameters, such that, you can set the Maximum Number of Stubs in a Recall Job, Time between recalls and Time to wait after maximum successive recalls limit is reached.
You can restore the system state of a client, backed up on a specific date and time.
In the archive phase, File Archiver for BlueArc will archive files meeting the pre-set archive criteria and, if applicable, put them into a list for the stubbing phase and prune the expired stubs. This helps in secondary storage space reclamation.
The BlueArc File Archiver documentation uses the following terminology:
|A proxy client is any computer on which the File Archiver Agent is installed to archive and recover data residing on a BlueArc File Server.|
|Migration archiving is a process of periodically moving unused or infrequently used BlueArc data on a host computer to secondary storage, thereby reducing the size of data on the primary storage.|
|The stubbing phase starts after the archive phase succeeds. Stubs are placeholders of the original data after it has been migrated to the secondary storage. Stubs replace the archived files in the location selected by the user during the archive. However, stubs will only be created if the subclient properties were configured to create them during archive.|
|The archived and migrated data can be recovered in any of the following three methods:
|If the subclient is configured to create stubs, you can perform a recall operation from a Windows computer for recovering the stubs. A recall is any action that causes an open and read to be executed on the stub, which automatically initiates a recovery operation.|
|Multiple stub recoveries are submitted to the Job Controller as one job called a Persistent Recovery job. The job will wait for approximately 5 seconds in order to allow other stub recovery requests being submitted on the same client to be batched into the same job.|
