SpareSync software

SpareSync is a software product designed to ensure the smooth operation of the managed system using a secondary server, through continuous unidirectional synchronization of the managed system data, including databases and file synchronization, as well as producing automatic transition into the maintenance mode on the secondary server when the primary one is unavailable by amending the appropriate DNS-record using Dynamic DNS (RFC 2136) protocol.

Two main functions

In operation, SpareSync performs two main functions: data synchronization from the primary to the secondary server, and monitoring of the primary server by using the secondary one. If necessary, it switches to the maintenance mode on the secondary server. Monitoring the primary server from the secondary server is carried out by periodic messaging, and the secondary server monitors the operation of the managed system (located on the primary server) through periodic requests of the test page and by checking its successful receipt.

How it works

1. Default operating mode. Data from MS SQL and selected file directories is continuously synchronized with the backup server.

2. If the primary server is unavailable (loss of connectivity or problems on the server itself), user traffic is automatically routed to the backup server.

3. Switching from the backup server is initialized by the SpareSync interface at a time when normal operation of the primary server is restored. All data that was received on the backup server is copied to the primary one, and the system returns to the initial state (Step 1).


+ In the normal operation mode, SpareSync creates hot standby system. It continuously monitors changes in the MS SQL database and the selected files and transfers them to the backup server.

+ In event of a failure, it will immediately switch all your users to your hot standby web service in another data center, cloud or server.

+ It works 24/7 and does not require significant costs for deployment and maintenance.
