 SAN Cluster Backup best practices
The following question was recently submitted via e-mail by a user: I currently use SAN based clusters with 10 2-node passive and active clusters. They work fine, but I want to know: What happens if we shut down the nodes unexpectedly (eg, power failure) and when we go to start them, they don't work? In other words, what if we have to restore from backup, having backed up nothing but the stores...can we do it? How do most enterprises do their cluster backups?

Answer Wiki:
For our file servers we take clones of the LUNs and keep as many as will fit in the SATA drives that we have on the SAN. For our SQL Servers we back them us using the native SQL Server backup commands to a LUN within the SAN, which we then clone and keep several of. In the event that we lost a LUN, we would simply present the clone back to the host and copy the LUN from SATA to Fibre.
