Oracle Recovery Manager (RMAN)

Oracle Recovery Manager (RMAN)

Oracle Recovery Manager (RMAN) users can efficiently protect and recover databases with a lower cost up front and a lower cost over time using ExaGrid Tiered Backup Storage.

Customers can simply send Oracle backups via the RMAN utility set directly to ExaGrid.

ExaGrid offers a disk-cache Landing Zone so that database backups are written straight to disk. The data is in its native format (undeduplicated) for fast restores. ExaGrid tiers the data into a long-term retention deduplicated data repository for low-cost long-term retention storage.

ExaGrid offers the best of both worlds by providing the most recent backups in a non-deduplcated format for fast restores, but also delivers a 10 to 50:1 deduplication ratio for low-cost, long-term retention storage. ExaGrid supports Oracle RMAN Channels for up to 2.69PB databases with the fastest backup, fastest restore performance, and performance load balancing.

ExaGrid enables the fastest Oracle RMAN Backups with Performance Load Balancing utilizing Oracle RMAN Channels. With ExaGrid’s Oracle RMAN Channels integration, ExaGrid customers get built-in performance load balancing, and global deduplication across all systems.

What Is The Fastest Oracle RMAN Storage Solution?

The fastest backup and recovery storage solution for Oracle RMAN is ExaGrid Tiered Backup Storage.

When using alternative solutions that provide inline deduplication with fixed-compute media servers or front-end controllers, as Oracle data grows, the backup window expands because it takes increasingly longer to perform deduplication. ExaGrid solves this problem with a scale-out storage architecture.  Each ExaGrid appliance has Landing Zone storage, repository storage, processor, memory, and network ports. As data grows, ExaGrid appliances are added into the scale-out system. With the combination of Oracle RMAN integration, all resource grow and are utilized linearly. The result is high performance backups and a fixed-length backup window regardless of data growth.

How Does The ExaGrid Landing Zone Work With Oracle RMAN Backups?

Each ExaGrid appliance includes a disk-cache Landing Zone. Oracle RMAN data is written directly to the Landing Zone versus being deduplicated on the way to the disk. This avoids inserting the compute intensive process in the backup – eliminating a performance botttleneck. As a result, ExaGrid achieves backup performance of 488TB/hr. for a 2.69 full backup including Oracle databases. This the same speed as low-cost primary storage disk and is 3 times faster than any traditional inline data deduplication..

What Is The Fastest Oracle RMAN Recovery Solution?

ExaGrid provides the fastest recoveries for Oracle RMAN backups.

ExaGrid maintains the most recent backups in its Landing Zone in the Oracle RMAN’s native format, undeduplicated.  By keeping the most recent backup in an undeduplicated form, Oracle customers avoid the lengthy data rehydration process that occurs if only deduplicated data is stored. The result is that you can get your data back in minutes versus hours for traditional inline deduplication solutions. In most cases, ExaGrid is the same speed as primary storage disk for restores and at least 20 times faster than any solution that only stores deduplicated data as ExaGrid avoids the compute intensive deduplication rehydration process.

Oracle RMAN Customers Experience Unparalleled Scale With ExaGrid Intelligent Repository

When an ExaGrid system needs to be expanded, appliances are added to the existing scale-out system. To ensure the most efficient use of resources, ExaGrid employs Global Deduplication to ensure that all data in the entire system is deduplicated across ALL APPLIANCES.  ExaGrid has global deduplication and also automatically load balances across all the repositories in an ExaGrid scale-out system providing for the best deduplication ration and also that no repository is full while others are under-utilized.  This allows for optional storage use of the deduplicated data repository in each appliance.

ExaGrid takes only a few minutes to configure and is often fully operational in under 3 hours.

Data Sheet:
ExaGrid and Oracle RMAN

The use of primary storage as a backup target adds tremendous cost and complexity of protecting Oracle databases. These databases often represent some of those most critical assets in the data center – customer information, financials, human resources information, and a variety of other critical elements. Oracle database administrators must ensure they can be recovered in the event they are corrupted or lost.

ExaGrid eliminates the need for expensive primary storage (due to the amount of disk required for long-term retention) for database backups without affecting the ability to use familiar built-in database protection tools.  While built-in database tools for Oracle and SQL provide the basic capability to back up and recover these mission-critical databases, adding an ExaGrid disk-based backup appliance allows database administrators to gain control over their data protection needs at a lower cost and with less complexity. ExaGrid’s support of Oracle RMAN Channels provides the fastest backup, fastest restore performance, and failover for multi-hundred terabyte databases.
