8 Ways to Reduce the Impact of a Server Failure

Filed under - Archived Content,

Chris Key explains how to reduce the impact on your contact centre in the event of a server failure.

One of the most common causes of server failure and data loss in contact centres is hard-drive failure. This is because most disk drives today still use moving parts. Solid state drives (SSDs), which have no moving parts, are available, but they can suffer degradation after a number of years depending on usage.

Hostcomm has more than 300 servers within its network which is located in across five data centres. Having this many servers gives us a good insight into the likely causes of a server failure and possible data loss. We’ve drawn on this experience to create data-management and back-up processes for our contact centre clients.

1. Regularly changing servers

This ensures the hardware always has a reasonably long “shelf life”.

2. RAID arrays

This mirrors the data over two or more disk drives so that if a drive fails the others can instantly take over.

Hardware RAID is required, not software RAID, which requires too much server resource.

3. Server clustering

This spreads the server components over several physical machines, meaning there is no single point of failure.

4. Remote database backup

Having a remote (offsite) backup protects against disasters relating to the server or data-centre.

5. Master/Slave database set-up

This mirrors the database to another local machine which is ready to take over if the main server fails.

6. FTP transfer

Transferring the database and call recordings overnight to a remote server.

7. Portable drive backups

This can be done if the data cannot be copied over an internet connection due to its size.

8. Replicating to a CRM system

Thereby having two sources of live data.

Many business are reducing their data back-up burden by moving their systems to cloud contact centres. By hosting their data in the cloud, they can reduce the cost and burden of maintaining on-premise hardware.

But this doesn’t remove the risk of server failure and data loss. Find a cloud contact centre provider with experience and well-defined processes so you can focus on your contact centre performance.
