Replication

WAN Optimized Off–site Disaster Recovery Protection

Permabit Enterprise Archive’s Replication is designed to address operational and compliance requirements for the replication of information to one or more remote sites.  A dedicated access node leverages Scalable Data Reduction™ (SDR) technologies to ensure that replication is both fast and efficient.

Permabit’s built–in replication offers a wide range of flexibility.  Each volume on a Permabit Enterprise Archive™ can be replicated to any other remote site.  This enables a variety of replication configurations.

• At its simplest, an enterprise can have a single live site, and a single disaster recovery site.  All data is available in a read–only form at the DR site, and can be promoted to being live with a single mouse click.

• A larger business with two active sites can have each site use the other as a disaster recovery standby, eliminating the need for a dedicated DR system.

• An enterprise with many remote offices can deploy a single, consolidated DR site to which all other systems can replicate.   Permabit’s SDR identifies duplicate data from multiple sites, greatly reducing the storage requirements at the central DR facility.

Replication and Scalable Data Reduction

Through the combination of SDR compression and deduplication, Permabit’s systems enable enterprises to cost–effectively accelerate WAN replication.  When a replication event occurs, only the compressed data that has not been previously replicated is written to the remote system.  In a many–to–one scenario, if the same data is replicated from multiple systems, that data will only be written once to the central replica site.  For large businesses with multiple branches, this can result in substantial performance benefits over traditional WAN acceleration schemes.  In addition, Permabit replication provides advanced levels of data protection to ensure that archive data is always accurate and recoverable.

Permabit Features:

• WAN Optimized:  Leverages SDR to deduplicate and compress data before it is transmitted to a remote site.

• One–to–One Replication:  Allows for replication from a primary site to a secondary site for disaster recovery scenarios.

• Many–to–One Replication:  Allows for multiple sites, such are remote sites, to be replicated to a single site, such as a data center, for remote site disaster recovery scenarios.

• Many–to–Many Replication:  Allows any site to replicate to any other site for cross–site, such as multiple data centers, disaster recovery.

• Asynchronous Replication:  Replication can be scheduled to occur as frequently as every five minutes.

• Volume Level:  Replication can be configured at the volume level providing flexibility in determining which data requires off–site disaster recovery protection.

• Single–Click Promotion:  Replicated data can be promoted from read only to live with a simple mouse click.
