ExaGrid Deduplication Provides Storage Savings for Clients
Dimension Data appreciates how ExaGrid’s deduplication saves costs for clients and enables a long-term solution that accounts for data growth.
“One client I work with is primarily snapshotting server infrastructure through NetBackup and transferring the data back into ExaGrid storage. The environment consists of almost 500 physical servers at this stage, which consists of file-level backups, VMs, SQL databases, Oracle applications, databases, application layers, and user data,” said Burger. “We follow the industry’s best practice standards – so we perform daily incrementals, weekly, and monthly backups. We’ve also implemented quarterlies, along with our yearly backups. Our clients keep retention periods up to seven years on critical systems, which is often required by law for audits in South Africa. It’s imperative that we have great deduplication!”
ExaGrid’s innovative approach to data deduplication minimizes the amount of data to be stored by using zone-level data deduplication across all received backups. ExaGrid’s patented zone-level technology stores only the changed data at a granular level from backup to backup instead of storing full copies. ExaGrid uses zone stamps and similarity detection. This unique approach reduces the disk space required by an average of 20:1 and from 10:1 up to 50:1 depending on data type, retention and backup rotation delivering unparalleled performance for the fastest backups and restores.
