You can configure iFileshare to offer enhanced availability for mission critical files by configuring a high availability group, consisting of a primary iFileshare server and a number of standby servers. Each server is a local or remote Enterprise Server region.
Files critical to your application can be replicated from a primary server to the standby servers. Should the primary server fail, you have up-to-date data (minus any in-flight transactions) available on the standby servers, and one of those can assume the role of primary server.
This failover process can occur automatically if the minimum number of servers within the group are present, which is three: one primary server, and two standby servers. If the group has fewer servers than this, you can perform a manual failover.
If other Enterprise Server work is hosted within the group, the setup must be consistent on each server, so that in the event of a failover, the non-Fileshare work can be continued on the new primary server.
