This post talks about some of the most common terms in enterprise communication, that is, cold or hot backup. Let's see what they mean.
1. 1+1 cold backup
A backup mode in which two systems with the same functions are deployed - one in active state and the other in standby state with power off. Once the active system encounters a fault, the standby system takes over the service of the active system.
2. 1+1 hot backup
A backup mode in which two systems with the same functions are deployed - one in active state and the other in standby state with power on. The standby system backs up the data of the active system automatically.
