When it comes to mission critical applications, most organizations count on high availability products to protect their mission critical applications. It looks like this; the mission critical application is mirrored or clustered. It is then backed up and in some way and replicated off-site. The problem is this is a stand-alone process from the standard data protection process and it is very expensive.
There is a feature that is becoming increasingly common in backup software solutions that we at Storage Switzerland call recovery in place, vendor terms are instant recovery and live recovery. This feature works first by the software doing incremental backups of the servers/virtual machines being protected, then when a recovery needs to happen the software can instantiate a virtual version of the volume on backup storage.
In this ChalkTalk Video we compare instant recovery to other high availability options.
