Clubessential's disaster recovery strategies are designed to 1) avoid loss of data; 2) provide uninterrupted service; and 3) recover with the least amount of down time.
Internet connectivity is assured through multiple independent connections, with separate switches, firewalls and routers.
Backup for electrical power failure is redundant, first by battery and then by diesel power.
All disk storage is configured with RAID controllers, so that the failure of a single disk will not cause down time. Backup database servers are being synchronized continuously and can take over processing quicky in the event of a database server failure.
A pool of webservers can easily handle the daily volume in the event of failure of any of the servers in the pool. Additional webservers can be added to the pool at any time.
Offsite backups take place weekly in case the entire data center is destroyed. |
