hot/cold sites?

By flyingknees ·
I am pretty much a novice when it comes to the area of hot sites and disaster recovery. Our network is fairly simple with a an ISP providing a T1, a single router, single firewall and roughly 50 internally NAT'd hosts. How can I create a duplicate hot/cold site from such an environment and what would it entail? I hear all this talk of SANS and EMCs and have even looked into some Veritas solutions for failover.
My estimated downtime is approximately 1-2 days at most if anything should happen.
Does anyone have any suggestions?

Of primary concern is making you have all your configuration information documented. Thorough documentation will allow you to quickly rebuild your network at a cold site if necessary. With a small site such as yours, you may contract with a vendor to provide you with equipment for your cold site. A hot site is probably cost prohibitive. Make sure you have adequate backup media; make sure you periodically perform test restores, and continually validate the integrity of your backed up information. Work with your telecom provider for services required at your cold site. Ideally, you can utilize office space at a secondary company site, such as a warehouse, that will allow you to have services installed with quick-start provisioning for turn-up when required.

Finally, a disaster recovery plan is not complete until you have tested it. Performing a disaster recovery operation will immediately highlight important issues and oversights.
