As we ourselves don't like to take technology for granted, we have backup servers of our own. All your data is not only stored on the servers assigned to your account, but there is a consistent real-time copy on an additional server at a separate location housed in a different datacentre building.
This is to ensure that if any of our servers experience downtime, perhaps due to maintenance, you would not be left stranded as you would still be able to log into our replication site instantly, without experiencing any network outages on your end. This level of protection would ensure that at any given time, there will be 3 individual copies of your data each located in different geographical locations.
This essential service is added peace of mind, especially in uncertain times where terrorist attacks and natural disaster are becoming more common and are compromising the security of our data.
