When Rapid NFS and Rapid CIFS are used with QoreStor they offer the following benefits:
Rapid NFS and Rapid CIFS enable write operation acceleration on clients that use QoreStor replication and NFS or CIFS file system protocols. Similar to OST and RDS, these accelerators allow for better coordination and integration between QoreStor backup, restore, and optimized deduplication operations with Data Management Applications (DMAs) such as CommVault, EMC Networker, and Tivoli Storage Manager. For the current list of qualified DMAs, see the QoreStor Interoperability Guide.
Rapid NFS is a new client file system type that ensures that only unique data is written to QoreStor. It uses user space components and file system in user space (FUSE) to accomplish this. Metadata operations such as file creates and permission changes go through the standard NFS protocol, whereas write operations go through RDNFS.
Rapid CIFS is a Windows-certified filter driver that also ensures that only unique data is written to QoreStor.
All chunking and hash computations are done at the media or client server level.
Rapid NFS and Rapid CIFS require you to install a plug-in on the client or media server, depending on your DMA and configuration. For details, see "Configuring and Using Rapid NFS and Rapid CIFS".
Rapid Data Access (RDA) with NetVault Backup and with vRanger provides the logical disk interface that can be used with network storage devices. QoreStor requires the NetVault Backup Plug-in for Rapid Data Access to integrate its data storage operations with NetVault Backup and vRanger. The plug-in is installed by default on the NetVault Backup and vRanger servers and QoreStor when the latest software updates are installed. Using the Plug-in for Rapid Data Access, NetVault Backup can take full advantage of key QoreStor and DR Series system features like data deduplication and managed replication.
When the Plug-in for Rapid Data Access is used with QoreStor, it offers the following benefits:
OpenStorage Technology (OST), by Veritas, provides a logical disk interface for use with network storage devices. QoreStor can use OST via QoreStor plug-in software to integrate its data storage operations with NetBackup and Backup Exec.
RDA with OST allows for better coordination and tighter integration between QoreStor system backup, restore, and optimized duplication operations and data management applications (DMAs). For a list of the supported applications, see the QoreStor Interoperability Guide.
Integration is done via a RDA with OST plug-in developed for QoreStor, through which data management applications can control when the backup images are created, duplicated, and deleted. The major benefit of RDA with OST is that it allows the deduplication operations to happen on the client side so that network traffic can be reduced.
The RDA with OST plug-in allows data management applications to take full advantage of such QoreStor features as data deduplication, replication, and energy efficiency. QoreStor systems can access the OpenStorage API code through the plug-in, which can be installed on the media server platform choice you make (Windows or Linux). The OST protocol allows the supported backup applications to communicate directly with QoreStor and determine whether a specific chunk of data already exists on the system. This process means that if the data already exists, only the pointers need to be updated on QoreStor, and the duplicate chunk of data does not need to be transferred to the system. This process provides two benefits: it improves the overall backup speed, and also reduces the network load.
