Active-backup

Alteeve Wiki :: How To :: Active-backup

In Linux network bonding, 'active-backup', also known as "mode 1", is the bonding option optimised for the fastest fault detection and recovery.

It is the only bonding mode that does not aggregate bandwidth. That is to say, of you 'active-backup' two 10 Gbps interfaces, you will have 10 Gbps usable bandwidth, not 20 Gbps. This means that the performance available in a degraded state is unchanged.

This is the bonding mode used in Anvil! clusters.

Technical details are available in the kernel bonding documentation.
