Bacula and ExaGrid: Immutable Multi-Tier and Certified Backups

Do you want a backup storage solution that offers the fastest backup performance, storage savings from deduplication to lower costs, and helps you recover data in case of a ransomware attack?  If your answer is: “yes, yes yes!”, your solution has arrived.

ExaGrid Tiered Backup Storage for backup product line consists of six appliance models. Each appliance is sized for a full backup and for long-term retention.

Any ExaGrid appliance can be mixed and matched in the same scale-out system with any other size or age appliance, allowing customers to buy what they need as they need it. This pay-as-you-grow model allows up to 32 appliances in a single scale-out system.

All appliances and systems are managed by a single user interface. Multiple systems can be deployed in a single site, which allows for full backups up to petabytes.

ExaGrid offers various-sized appliance models that can be mixed and matched with up to 32 appliances in a single scale-out system. The largest scale-out system can take in up to a 2.7 PB full backup with an ingest rate of 488TB/hr. This is 3X faster than any other backup storage on the market.

As shown in Figure 1, the Bacula’s Aligned Driver, certified for use in ExaGrid’s entire line of appliances, provides reductions greater than 50:1, depending on backup retention and data variability.

ExaGrid, in conjunction with Bacula, supports many unique features, integrations and interfaces to improve security, performance and scalability, such as: native immutability in Bacula and ExaGrid, multiplexing and parallelism of backups, scale-out for virtually infinite ExaGrid appliances, and global deduplication for easiest job management.
ExaGrid deduplication can even leverage backup software deduplication and add additional deduplication to increase overall rates, resulting in even greater disk and bandwidth savings.

ExaGrid is the only solution that provides a unique disk-cache Landing Zone that maintains full copies of the most recent backups of all Bacula workloads so that restores, recoveries, VM boots, and copies to tape are as efficient as possible – as fast as backups to disk.

As shown in Figure 2, presenting ExaGrid volumes to Bacula is extremely easy to configure, as are immutable replications.

On the Bacula side, the Aligned plugin showed optimal reduction with 128Kb blocks. As shown in Figure 3, backups can be extremely fast with the ingestion of many terabytes in an hour.

In addition to all this, ExaGrid’s team in the United States worked in collaboration with Heitor Faria, a renowned researcher in the backup field, adding credibility and optimizing the certification process.
