Customer Benefits Disaster Recovery
Replication technology has typically been used to address disaster recovery issues. Disaster recovery
is still the driving business case behind replication. Remote replication can be implemented from the
production site to one or more remote sites across a campus, across town, across a state or across
the country. When a disaster strikes the primary location, the applications can be brought up at the
remote site and continue processing against the replicated copies. When the primary site is back
online, the replication can be reversed and when the data is resynchronized, processing can be
switched back to the primary site and business can continue. In the past, if an e-mail system
experienced a disaster it was an "oh well" moment. The loss of a day or more of e-mail was not
considered important. Today, e-mail is a critical component of many companies' business plans and
recovering e-mail after a disaster quickly and completely is required.
Maintenance
HP Remote Snap software can also be used to solve other business needs. For instance, E-mail
servers may need periodic maintenance that can take hours to complete. With remote replication in
place, the downtime can be minimal (as long as it takes to bring the remote peer of the primary e-
mail server online). The primary server can be worked on (patches, hardware upgrades, etc.) and then
brought back online and into production. A whole datacenter can be failed over to a remote site on
purpose to perform maintenance on generators, air conditioning, etc. Replication can also be used to
perform a datacenter move with minimal downtime (fail everything to the DR site, move the
production datacenter to its new location then fail the DR site back to the new datacenter).
