Disaster recovery within secure environments
View Patent ↗Systems and processes include a disaster recovery system for a production site. The disaster recovery site may include replications of at least a portion of information and/or applications from the production site. Requests for the production site may be redirected to the disaster recovery site according, as appropriate. The disaster recovery site may be tested while without substantially inhibiting operation of the production site
1. A method comprising:
replicating information stored on a production site on to a disaster recovery site coupled to the production site, wherein the disaster recovery site and the production site include mechanisms to restrict access;
allowing testing of the disaster recovery site while allowing the production site to substantially continue operations;
terminating replication of said information from the production site to the disaster recovery site during testing of the disaster recovery site;
receiving a request for access to data on a production site;
applying a forwarding rule to the request;
redirecting the request to the disaster recovery site if criteria of the forwarding rule have been satisfied; and
testing global switch services if the request is via the Internet.
2. The method of claim 1 wherein said information stored on the production site is stored on a storage area network of the production site.
3. The method of claim 1 further comprising allowing access to the disaster recovery site.
4. The method of claim 3 wherein allowing access to the disaster recovery site includes allowing access to at least one of a storage area network of a disaster recovery site, an application server of a disaster recovery site, a proxy server of a disaster recovery site, or a database server of a disaster recovery site.
5. The method of claim 1 wherein applying the forwarding rule includes determining if a disaster event has occurred, and redirecting requests for the production site to the disaster recovery site if a disaster event has occurred.
6. The method of claim 1 wherein applying the forwarding rule includes determining if notice of a disaster event has been received, and redirecting requests for the production site to the disaster recovery site if the notice has been received.
7. The method of claim 1 allowing access to the production site if criteria of the forwarding rule has not been satisfied.
8. The method of claim 1 further comprising testing a net cache of the disaster recovery site if the request is via an intranet.
9. A method comprising:
receiving a request for access to data on a disaster recovery site coupled to a production site, wherein the disaster recovery site includes information from the production site, and wherein the disaster recovery site and the production site include mechanisms to restrict access;
determining if the request is for testing the disaster recovery site;
terminating the coupling between the disaster recovery site and the production site, if the request is for testing the disaster recovery site;
allowing the production site to substantially continue operating, if the request is for testing the disaster recovery site;
allowing access to the disaster recovery site, in response to the request; and
testing a net cache of the disaster recovery site if the request is via an intranet.
10. The method of claim 9 further comprising testing global switch services if the request is via the Internet.
11. The method of claim 9 further comprising testing a storage area network of the disaster recovery site.
12. The method of claim 11 wherein testing a storage area network includes determining whether the storage area network satisfies recovery criteria.
13. The method of claim 9 wherein allowing access to the disaster recovery site includes allowing access to a storage area network of the disaster recovery site.
14. The method of claim 9 wherein allowing access to the disaster recovery site includes executing one or more applications residing on the disaster recovery site.
15. A machine-readable medium storing instructions for a disaster recovery system to perform operations comprising:
transmitting data from a storage area network of a production site to a storage area network of a disaster recovery site, and wherein the disaster recovery site and the production site include mechanisms to restrict access;
receiving a request for data on the disaster recovery site;
determining if the request for the disaster recovery site was for testing of the disaster recovery site;
terminating the coupling between the production site and the disaster recovery site, if the request is for testing the disaster recovery site;
allowing access to the disaster recovery site in response to the request; and
testing a net cache of the disaster recovery site if the request is via an intranet.
16. The machine-readable medium of claim 15 wherein receiving a request for the disaster recovery site comprises receiving a redirected request for the production site, wherein the redirected request was redirected from the production site to the disaster recovery site due to a disaster event.
17. The machine-readable medium of claim 15 wherein instructions for a disaster recovery system to perform operations further comprise allowing access to the storage area network of the disaster recovery site.
18. The machine-readable medium of claim 15 wherein instructions for a disaster recovery system to perform operations further comprise allowing access to an applications server of the disaster recovery site.
19. The machine-readable medium of claim 15 wherein instructions for a disaster recovery system to perform operations further comprise testing global switch services if the request is via the Internet.
