Bonhams has cut the number of servers it uses to backup its data by 75%.
The auction house, which recently sold the 1950s F1 Mercedes which took Juan Manuel Fangio to his second world title, for $29.7m, reduced its US servers from 35 to eight with a new open-source backup system delivered by Quru and using Acronis technology.
Roland Whitehead, CEO of Quru, said the Red Hat Enterprise Linux-based solution his company installed would have been 40% more expensive had Bonhams opted to used VMWare-based architecture.
"We migrated Bonhams over to open source software for the foundation of the upgrade and to standardise diverse platforms," he said.
"This dramatically reduced licensing costs and enabled new disaster recover capabilities that would have been prohibitively expensive on proprietary systems."
The 35 servers in Bonhams' New York and San Francisco data centres were replaced by eight IBM System x3650 class servers, which are used as virtualisation hosts in a Red Hat Enterprise Virtualisation version 3.1 cluster.
The Acronis software means Bonhams can take live snapshots of its virtual machines and back them up at either site, then synchronising those files to each data centre.
"In the event of a catastrophic failure at either site, we can quickly restore the virtual machine from the most recent backup, and all services will be up and running within hours instead of days," said Simon Chiu, Bonhams' senior systems engineer in San Francisco.
