There are a number of ways replication can be used in conjunction with traditional backup, and some backup software tools are integrating with replication and array-based snapshots to facilitate secondary data management.
However, there are a number of things to consider before deploying the technology as a part of your DR strategy. This collection of recent expert advice is by no means an exhaustive study on the topic, but it is a good place to start learning more.
replication for remote site backup
Replication tools are used in many different ways. This piece offers insight on how replication can be used for remote site backup and DR.
bidirectional replication can be used for DR
Bidirectional transactional replication lets two or more Windows servers serve as both "publishers" and "subscribers" of data. Learn how it's is used for disaster recovery in this piece.
replication and CDP are used for disaster recovery
A couple years ago, CDP was a big buzzword, but the technology didn't quite catch on. These days, a combination of snapshots and replication is being used as a sort of "near CDP" in some organizations' backup strategy. Learn how CDP, snapshot and remote data replication are used for disaster recovery.
vs. hypervisor-based replication

is cloud replication performed?
Cloud backup is a hot topic right now, although our research shows that it has not yet been widely adopted. This piece details replication is performed when using cloud storage as a target.
