The Remote Office Backup solution is designed to seamlessly replicate data from
remote offices to a centralized data center, where it is stored on a magnetic
library (disk) for ready access. Consolidating all backup data at the centralized data
center provides redundancy for disaster recovery, as well as an alternate source
for normal data recovery operations. This innovative solution is easily deployed,
without any disruption of current data protection operations, and with no impact
on your end users at remote offices; no additional software or configuration is
required on client computers, as only MediaAgents are involved. Even more
importantly, the data from every iDataAgent deployed at remote offices can be
replicated to the centralized data center, no matter the source of the data ‐‐ all
supported file systems, databases, and data types.
Significant benefits result when this solution is combined with several other
available features; de‐duplication at the remote office is performed before data is
replicated to the centralized data center, greatly reducing the network load.
Replication Compression provides a similar benefit, compressing data at the
remote office, replicating it across the network to the centralized data center,
then uncompressing it on the destination MediaAgent; finally, Replication
Encryption can be employed to ensure the security of data transmitted across
non‐secure networks, by encrypting the data before transmission and
automatically decrypting it on the destination MediaAgent at the centralized data
center.
Backup and recovery of company data at primary sites typically places high
demands on the resources of a company’s IT department. The result is that data
protection is neglected at the smaller, remote sites even though information at
these regional offices or branch offices may be as important as that found at the
primary data center. A lack of technical resources at remote sites further
complicates the problem. Even if standard backup‐disk technologies are
implemented at remote sites, the data continues to sit there unless a tape DR
strategy is implemented because there is simply too much data to reasonably
replicate back to a centralized site for DR purposes.
