Is Storage the Only Consideration? No. Performance Matters.
ExaGrid’s Tiered Backup Storage approach avoids the typical downfalls associated with deduplication solutions: backup, restore, and replication performance issues. Backups and restores of the latest versions are written to and from a disk-cache Landing Zone, avoiding inline processing, rehydration, and ensuring the highest possible performance. ExaGrid is 3 times faster for backup and up to 20 times faster for restores than any other deduplication appliance solution.
How Does ExaGrid Achieve the Fastest Backups, Shortest Backup Window, and Offsite Replication to Meet Your RPOs?
ExaGrid enables organizations to meet their backup windows and ensures that critical data is replicated offsite within the Recovery Point Objective (RPO) using Adaptive Deduplication and Landing Zones.
Data deduplication is highly compute intensive, so when performed during the backup window, it slows down ingest performance, lengthening the backup window and delaying replication. The result: missed RPOs. ExaGrid uses a disk-cache Landing Zone for fast backups and restores (performance tier) and then tiers the long-term retention data down to a deduplicated data repository.
ExaGrid is the best of both worlds. ExaGrid has combined the performance of low-cost primary storage disk on the front-end with the cost efficiency of a deduplicated data repository on the back end. Because ExaGrid is a scale-out storage architecture (providing not just storage, but also compute, memory, and replication management technology), during ingestion, adaptive deduplication is able to monitor ingest rates and resource consumption. Adaptive deduplication identifies when to perform deduplication processing and data replication during the backup cycle. Adaptive deduplication will deduplicate and replicate data to the disaster recovery (DR) site during the backup window (in parallel with the backups) but not inline between the backup application and the disk. Should a new backup or in-progress backup require additional compute or memory, adaptive deduplication will adjust deduplication and replication processing to dynamically meet the highest priority needs of the environment.
This unique combination of a Landing Zone with adaptive deduplication provides the fastest backup performance, resulting in the shortest backup window as well as a strong disaster recovery point (RPO).
What About Restore Performance?
ExaGrid is the only deduplication solution that performs as well for restore as straight disk solutions. How do we achieve this?
The Landing Zone. ExaGrid stores the most recent backup copies in native Veeam format, undeduplicated on the Landing Zone. This allows VM boots to occur in seconds to single digit minutes versus hours compared to solutions that only store deduplicated data.
How Does ExaGrid Achieve the Industry’s Fastest Restores, VM Boots, and Offsite Tape Copies?
Ninety-five percent of restores or more, VM boots, and offsite tape copies come from the most recent backup, so keeping the most recent backup in only deduplicated form will require a compute-intensive, time-consuming data “rehydration” process that will slow down restores. VM boots can take hours from first generation inline deduplicated data approaches. Since ExaGrid writes directly to the disk-cache Landing Zone, as you would to low-cost primary storage disk, the most recent backups are kept in their full, undeduplicated, native form. All restores, VM boots, and offsite tape copies are disk-read fast as the overhead of the data rehydration process is avoided.
ExaGrid Tiered Backup Storage provides the data for a VM boot in seconds to single-digit minutes versus the hours it takes for inline data deduplication appliances that only store deduplicated data. ExaGrid maintains all long-term retention in a deduplicated format for storage efficiency.
ExaGrid provides the best of both worlds – writing to ExaGrid’s disk-cache Landing Zone delivers the fast ingest and restore performance of straight disk while also leveraging the cost savings gained with long-term deduplicated repository. ExaGrid is the only deduplication solution with these combined benefits in a single product.
What About Data Growth? Will ExaGrid Customers Need a Forklift Upgrade?
No forklift upgrades or abandoned storage here. ExaGrid hyperconverged appliances are simply added to a scale-out system for easy backup storage growth as data grows. Since each appliance includes all compute, networking and storage resources are extended with each new addition — as data grows, the backup window stays fixed length.
Traditional deduplication storage appliances utilize a “scale-up” storage approach with a fixed resource front-end controller and disk shelves. As data grows, they only add storage capacity. Because the compute, processor, and memory are all fixed, as data grows, so does the time it takes to deduplicate the growing data until the backup window is so long that the front-end controller has to be upgraded (called a “forklift” upgrade) to a larger/faster controller which is disruptive and costly.
ExaGrid provides full appliances in a scale-out system. Each appliance has Landing Zone storage, deduplicated repository storage, processor, memory, and network ports. As data volumes double, triple or more, ExaGrid appliances provide all required resources to maintain a fixed-length backup window. If the backups are six hours at 100TB, they are six hours at 300TB, 500TB, 800TB, up to multiple petabytes – with global deduplication.
With ExaGrid, expensive forklift upgrades are avoided, and the aggravation of chasing a growing backup window is eliminated.
ExaGrid Enables Your Favorite Veeam Features
With ExaGrid and Veeam you can:
- Boot a VM from the backup storage system when the primary VM environment is offline
- Perform audits or Sure Backups to prove to an internal or external audit team that VMs can be booted or restored in the case of a failure
- Supports Data Lab for testing and Dev Ops
- Create a synthetic full on a regular basis in order to ensure reliable full backup restores; integration of the ExaGrid-Veeam Accelerated Data Mover with ExaGrid’s Landing Zone provides synthetic fulls that are 6x faster
- Boot VMs on the backup system to test patches, configurations, and other updates before rolling out to the production environment
- Maximize ExaGrid’s full support of Veeam’s Scale-Out Backup Repository (SOBR)
