Read below for an excerpt about Disaster Recovery:

As its name implies, a data snapshot — think Polaroid or Instagram — captures a distinct point at the storage level. It’s an appropriate data backup solution for certain types of data, but inappropriate for others.

Because it doesn’t have the intelligence of true backup system, snapshots can have issues with memory intensive applications and can result in a state of “crash inconsistency.”

Backup software can communicate with applications. “With a full data backup, you can be sure that your server – if you have to restore it – is in a “crash consistent” state, and you can be sure that your data is available,” Aiello says.
