IntelliSnap Guide Objective and Overview. Integration Requirements for IntelliSnap. Security and Storage Policy Best Practices. This guide is an introductory overview of the storage array with its built-in technology and feature sets, hosy with the licenses and configuration requirements to integrate these controls with the Commvault software.
This guide also provides detailed descriptions for configuring hardware-based snapshot mechanisms using the Commvault software. The IntelliSnap technology of the Commvault software is a modernized approach for data protection, allowing hardware storage systems snapshots to merge directly into the backup process. By automatically integrating application intelligence with array snapshot abilities, Commvault is able to reach through the application and file systems into the storage array to accomplish the following:.
When a scheduled backup job for a defined application runs, the source system quiesces the selected applications and automatically creates a set of persistent snapshots within the production storage system. With a confirmation of the successful snapshot creation by the host, aand workload in the protection job shifts to a secondary proxy server to offload backup operations.
This shift managemeent the production host, which returns to full production side operations. This allows the creation of a witu data image in minutes with Recovery Point Objectives RPOs aligning with the frequency of schedule. The Proxy completes the second half of the protection job by reaching into the SAN, mounting the snapshot and automatically indexing and cataloging the file-level contents of the snapshot s.
Unlike the hardware-based snapshot approach, Commvault blends the speed and efficiency of array snapshots directly into the backup and restore process, offering full system c,ariion or single file restore. Once clarijon content-aware indexing completes, the snapshot is retained in the array as a persistent recovery copy to provide a quick recovery option to revert or restore the data volumes. The Proxy serves a secondary role after the snapshot executes. The same snapshots will mount and copy the relevant file contents from the snapshot and apply deduplication to the data during transport to the backup snpaview destination.
As data moves into the backup copy, the original indices are preserved and stored along with the data to ensure access from any location.

Data encryption is also another critical feature to apply to data to keep it highly secured from unwanted eyes. These components provide the storage-system performance and functionality for today’s Small-to-Medium Business needs. The following sections provide a brief description for each component. EMC provides connectivity between the customer environment and the Clariion through Storage Processors.
There are two Storage Processors for each of the Clariion systems for Trespassing capability Fail-over capability. Ibtegration storage processor provide the following:. Both storage processors reside within a Storage Processor Enclosure, and each provide user interface and command line interface level console connection to provide customers ways to manage Disk provisioning through Navisphere Clariion management software.
An example report from Navisphere with the basic configuration of each Storage Processor is shown below. Disk Array Enclosure DAE is a main component that connects with the Back-End modules from each of the storage processors presenting raw disks for use. Each DAE contains 15 disk drives in a Fibre Channel loop, and can be daisy chained to loop up to disk drives per loop. All write cache contents will be stored in an event of power failure for complete restoration upon power-on.
An example of the Flare code running on a particular Clariion model is shown below. These agents also periodically retrieve information from the clariioj system events and can notify personnel by e-mail, pager, or modem when any specific event occurs.
It allows the following basic functions:. By default, the Navisphere Manager is installed along side with Navisphere Storage Manager Server on the storage manxgement. It can also be installed on Windows Servers.
It is the traditional way to take a full copy of the source volume to a clone volume at a block by block level. It provides the ability to provide a Point-In-Time view of the source volume using manageent with gost volumes.
Pointers will initially point to the original data on the source volume. Once new data is written to the source volume, the original data is copied to the reserved volume to preserve the Point-In-Time view. During the first SnapView session on a given source volume, a reserved volume is assigned to the source volume. If the SnapView session runs long enough that the reserved volume is filled, the next reserved volume will be assigned to the source volume.
The Commvault software supports all CX series models. AX series are not supported. For information on the supported storage systems for the Commvault software, see Hardware Snapshot Engine Compatibility Matrix.
Serial-ATA hosr are only supported in this model. Again, the high end doubles the maximum number of disks. Refer to the IntelliSnap Backup integrration Support document for a complete list of supported applications and platforms. IntelliSnap solutions require the appropriate agents as defined by the customer configuration. See the following terminology for reference in this document:.

Server mounting the snapshot or clone for backup purposes off of the Production Host. Agent for protecting the file system of a host. It is the base requirement for most Application i DataAgent. Agent for creating and managing snapshots as well as for writing data to backup targets. Enables application-aware snapshots to be created when backups are scheduled. Agent providing protection of Virtualization Environments without installing backup i DataAgents internal to the guests.
A CommServe, a necessary storage capacity, and MediaAgents must exist to enable a completely functional solution. On top of this basic infrastructure, you can configure the environments described below. The IntelliSnap base configuration requires the following agents on the Production Host:.
For a configuration where intehration mount off the host to a Proxy server, implement the following agents on the Proxy:. Protecting application databases and log volumes through an Array snapshot provide fast access for recovery and many flexible options for backups. IntelliSnap integrates application awareness together with the Array and Commvault to deliver all of the benefits of traditional streaming backups with all of the performance and proxy capabilities of a snapshot.
This application awareness allows backups with appropriate log management operations based on the snapshot data. When implementing for Application Environments simply add the appropriate Application i DataAgent to the IntelliSnap base maanagement as follows on the Production Host:.
For a configuration where snapshots mount off the host to a Proxy clariionn, implement hosh following agents on the Proxy. Refer to Getting Started – Setup Clients to select your application i DataAgent and perform the required deployment and configuration steps. IntelliSnap enables fast protection of large or volatile VMware environments without placing load on the production Virtualization Farm. IntelliSnap technology integration with the Virtual Server Agent enables the Array to perform backups in minutes even with large numbers of virtual machines and sizable data stores.
A dedicated ESX server for proxy data movement removes any utilization on the ESX farm providing file and folder recovery from the secondary tier of storage. To enable IntelliSnap for the Virtual Environment install the following on the physical server s or virtual hot-add guest s:.

EMC VNX/CLARiiON Storage System Guide for IntelliSnap
The Commvault software utilizes managdment different snavpiew replication mechanisms provided by EMC: This snapshot now provides availability for backup copy operations and high speed restore, mount and revert operations. A backup copy operation provides the capability to copy the snapshots to media and can be useful for creating additional standby copies of data.
When you enable backup copy, the snapshots are copied to media based on the rules specified for the snapshot copy during the IntelliSnap backup or at a later time. IntelliSnap provides a modernized architecture for handling backup operations within the ,anagement.
Proxy capabilities enable an array-based snapshot to mount off the host eliminating backup processes on the production servers. Each operating system with a IntelliSnap client requires a similar operating system for proxy execution.
Commvault will automatically link indexing information back to the original host enabling full application protection for recovery purposes. Execution of application integrity checks may also occur on the Proxy servers to validate the data prior to backup creation. For a configuration where snapshots mount off the host to a proxy server, deploy the following agents on the proxy server:.
You can validate the IntelliSnap configuration prior to running production jobs using the SnapTest utility. The Storage Array technology can be potentially dangerous without proper controls. Typical script based tools lack these controls and expose environments to high risk side effects with very little oversight or reporting.
A single miss-aligned scripted argument could cause massive data loss. Rather than risking the business with scripts or standalone tool sets, the embedded role based security system that Commvault provides allows you to entrust critical actions to the right users at the right time. In most medium to large environments, application, backup, and audit responsibilities may be distributed functions that need to be coordinated into a single policy.
For Example, a customer may have three specific roles within an operations environment:. The following table is an example of the Commvault Security Roles basic structure:. Managing proper retention on snapshot copies becomes another critical requirement.
Improper retention may cause the following:. Commvault storage policies are broken down into copies for managing retention on the proper tier of storage. In a typical storage policy for IntelliSnap, three copies will be available:.
Storage policy configuration varies from environment to environment. Based on this example, you may set the retention in the following way:. This configuration allows snapshot retention on a 48 hour rotation providing multiple high-speed recovery points available on the array to meet the SLA requirement. It also requires storage space allocation to maintain two persistent days of change for the associated clients.
Improperly setting retention and effects of days and cycles can adversely affect the available recovery scenarios for the business applications. You can also perform other operations with snapshots such as out of place refresh, single file recoveries, mount and browse capabilities, etc.
Refer to any of the Advanced documents for an specific Agent for the available operations you can perform to manage snapshots. SnapView Clone and Snap allow 1-to-Many relationships between the production volume and the clone volume or reserved volume.
When a IntelliSnap job starts, each job consumes a volume residing on a particular RAID group for each production volume as shown in the table.
