OnePass for Network Shares - Overview

The OnePass for Network Shares feature allows you to backup, archive, and recall data that reside on your file server.

How OnePass for Network Shares Works?

After OnePass is enabled on a client, users can create subclients with the content that they want to archive. The Windows File System iDataAgent is installed on a computer that acts as a proxy computer. Commvault uses the CIFS protocol to access the data that is located on the file server. For more information on backup and archive operations for CIFS shares, see Data Protection for NFS Shares, CIFS Shares, and UNC Paths.

When a backup starts, the proxy computer scans the file server for data that meets the archiving rules that you defined, and then creates the stubs.

Data that does not meet the archiving rules are backed up. The archived data is then moved to the MediaAgent. This frees up space on the file server, but the stub file acts as a place holder for the archived data.

When you recall the stubs, the proxy computer sends a recall request to the file server.

Benefits

After OnePass is enabled on a client, users can create subclients with the content that they want to archive.

Point-in-Time Recovery

In the event of a serious system failure, such as hardware, software or operating systems, you can restore data from a specific time range or from the latest backup.

Recall Throttling

You can configure the following stub recovery parameters:

  • Maximum Number of Stubs in a Recall Job
  • Time between recalls
  • Time to wait after maximum successive recalls limit is reached.

Deleted File Retention

You can define how long you want to retain the deleted items in your backup cycle.

Storage Space Reclamation

Stubs are pruned and the space on the file server is freed up based on the stub and storage policy retention rules.

What Is Archived

OnePass archives the files that reside on the network share file server.

The subclient filter does not filter the MediaAgent disk library mount paths from the subclient content. You must specify the volumes that contain disk library mount paths for subclient filter, else the entire disk library will be archived.

What Is Not Archived

The following file types and objects are automatically filtered from the archive operations by the system and are not archived.

  • Install folder
  • Job Results folder
  • Index cache folder
  • Log files folder
  • Windows system32 folder
  • Alias mount points to drive letter volumes*
  • Unix data residing on a Windows NFS share
  • Files with attributes of encrypted or sparse
  • Files with attributes of hidden and system
  • Files with extended attributes

Files Excluded from Archiving (Stubbing)

  • *.dll
  • *.bat
  • *.exe
  • *.cur
  • *.ico
  • *.lnk

Support

The OnePass feature for network shares supports any UNC path, except for Celerra file server UNC paths. For more information on backup and archive operations for CIFS or NFS shares and UNC paths, see Data Protection for NFS Shares, CIFS Shares, and UNC Paths.
