Storage Replication Software
Storage replication is becoming more popular in the enterprise and if you're already operating in a virtual environment, you have multiple replication solutions to choose from. While SAN products have been offering integrated hardware/software replication solutions for years, virtualization vendors have started integrating this feature into their newer products. VMware, for example, offers a storage replication feature in its newest version of vSphere. If you already have a SAN that supports replication you can choose how you want to replicate. Not a bad idea since VMware’s solution is version 1.0. One of the replication chief benefits is its ability to automate the process of data backup and redundancy.
Restoring your data is as simple as the original storage replication process. You just go online and switch over to the replicated server. Depending on your provider, the complexity of your infrastructure and your comfort level with technology, it may also be possible to set an automatic failover to prevent any customer-facing outage at all. But recovery is as simple as getting online and synchronizing the replicated data to the original server, restoring it to the state of its last backup. You will still have some data loss, the transactions, and records from the intervening period. But if that backup was recent, within the last day or two, the effort required to reconstruct lost transactions and records will be relatively minor.
It's important to understand that storage replication only insures you against hardware failures, and does nothing about the risk of accidental deletion or of your virtualization provider failing to follow best practices. If you have replicated your data, you have a copy of it as it existed at the moment you replicated it. But don't assume that your virtualization provider stores your replicated data at a different data center.

F.A.Q. about Storage Replication Software
What is Data Replication Software?
Data replication software supports data security, disaster resilience and business continuity by rapidly creating a data replica in a location independent of the data’s source. The software provides central management of replication policy across heterogeneous data sources and targets. Different from backups, data replicas update frequently rather than retain one unchanged copy for an extended period.
Data replication software ensures consistency for end-users accessing multiple data stores in the normal course of business. Other potential uses are zero-downtime data migration and multi-site replication for business continuity in case of site disaster. Data replication is a necessary part of long-term data retention and archiving. More recently, data replication software is offered as capably providing real-time transactional data delivery and integration into data lakes to support big data initiatives.
Vendors boast data policy compliance, any-point-in-time recovery and failover, and continuous replication with limited risk of data loss. They compete on providing minimum disruption to network activities and low bandwidth consumption, without cost to security.
