Today we await the arrival of a 100 year storm that threatens to surge New York harbor and the Long Island Sound by 6-11 feet!
In light of Hurricane Sandy barreling through the East Coast, I thought I'd review some of the very basics of DR.
1. Take backups (Fulls, Diffs, Logs) as often as your business requires. Ask your business areas bluntly: if a giant rock came crashing down on this server and destroyed it, how long could you go without data?
2. Make sure those backups make it somewhere off-site. Often this means to tape and an external off site backup store like Iron Mountain. If a disaster destroys your data center and you are forced to rebuild from scratch in a new location like Sunguard, you'd better have current off site backups.
3. Hardware failover is important (e.g. clustering) but also think about geographic failover/redundancy. Last week I discussed my love of Red Gate log shipping. Having a warm standby in a different geographic location is a very good hedge against local disruptions of the type many on the East Coast are fearing today.
Be safe out there everyone. This storm looks like it could be bad.
