Data replication was taking up to four hours to complete at Golden Plains Shire Council in Victoria before wide area network (WAN) optimisation software was implemented.
IS administrator team leader Carolynne Roberts said the slow data replication meant it could not meet recovery point objectives (RPO).
“We wanted the loss of only an hour's data in the event of a [systems] crash. A typical replication workload would take about three or four hours,” she said in a statement.
To solve the problem, it decided to implement WAN optimisation software developed by Silver Peak in 2013.
According to Roberts, data replication volumes have been reduced from 171GB of data down to 14.5GB, a reduction of over 91 per cent.

The Shire is also replicating its virtual machines across the WAN, carrying most day-to-day data including file, print and Internet access information.
In addition, Silver Peak has offered to help the council switch from hardware appliances to virtualized software products in the future.
“That's an excellent outcome for us because we don’t yet have our virtual infrastructure set up at our remote sites,” said Roberts. “To know that we can scale up our remote sites in the future simply by changing to a virtual license is fantastic.”
