with very tight recovery time objectives (RTOs)?
If your disaster recovery requirements include failover and failback, add these to your request for proposals (RFPs) from hot-site providers. Failover and failback can be performed by your IT department, and a number of products are available (e.g., Double-Take software products from Vision Solutions Inc.) to simplify the disaster recovery process. Make sure your hot-site vendor candidates support high-speed data mirroring so that the data needed for your low-RTO systems will be available as soon as you need it.
Not every data storage vendor or hot/cold site firm offers data mirroring. You may have to select a separate mirroring vendor to partner with the hot/cold storage vendor. Of course, price points for the increased storage and network bandwidth requirements (which are passed on to the client) will be higher.
