VM boots can take hours from first generation inline deduplicated data approaches. 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. How Does ExaGrid Achieve the Industry’s Fastest Restores, VM Boots, and Offsite Tape Copies? This allows VM boots to occur in seconds to single digit minutes versus hours compared to solutions that only store deduplicated data. The Landing Zone. ExaGrid stores the most recent backup copies in native Veeam format, undeduplicated on the Landing Zone. What About Restore Performance?ĮxaGrid is the only deduplication solution that performs as well for restore as straight disk solutions.
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). 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.
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. Adaptive deduplication identifies when to perform deduplication processing and data replication during the backup cycle. 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. 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. 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.ĮxaGrid is the best of both worlds.

How Does ExaGrid Achieve the Fastest Backups, Shortest Backup Window, and Offsite Replication to Meet Your RPOs?ĮxaGrid 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.ĭata deduplication is highly compute intensive, so when performed during the backup window, it slows down ingest performance, lengthening the backup window and delaying replication. ExaGrid is 3 times faster for backup and up to 20 times faster for restores than any other deduplication appliance solution. 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. Performance Matters.ĮxaGrid’s Tiered Backup Storage approach avoids the typical downfalls associated with deduplication solutions: backup, restore, and replication performance issues.
