Highlights
Deduplication reduces the amount of disk storage needed to retain and protect data by ratios of 10 – 30x and greater, making disk a cost–effective alternative to tape. Data on disk is available online and onsite for longer retention periods, and restores become fast and reliable. Storing only unique data on disk also means data can be cost-effectively replicated over existing networks to remote sites for disaster recovery (DR) and consolidated tape operations. EMC Data Domain deduplication storage systems integrate easily with existing infrastructures and can be used seamlessly with a variety of data movers and application workloads. By consolidating to a common disk-based target, you can avoid creating disparate islands of data and storage. A single EMC Data Domain system can be used for backup and recovery, protection of enterprise applications (e.g., Oracle, Microsoft Exchange, VMware and others), archiving and online reference storage. EMC Data Domain systems deduplicate data inline during the backup process. Deduplicated data can be stored onsite for immediate restores and longer-term retention on disk. The deduplicated data can also be replicated over the WAN to a remote site for disaster recovery operations, eliminating the need for tape-based backups, or for consolidating tape backups to a central location. Data Domain systems provide flexible replication topologies to optimize backups, such as full system mirroring, selective, bi-direction, many-to-one, one-to-many and cascaded.
Deduplication storage systems for next-generation backup and recovery. Scalable Data Domain systems feature high-speed, inline deduplication and network-efficient replication. A single system can reduce storage requirements 10 – 30x and protect up to 28.5 petabytes of logical capacity.
