We have seen a monumental change in how data is stored, from the good old floppy disk to high-speed Solid State Drives. Traditionally data would be backed up according to a schedule onto something like a tape drive and then physically relocated to another site in case of a physical incident such as theft or natural disaster. But in today’s age, we are able to send this data into highly secured data centres that can be replicated around the world.
So what exactly is Backup as a Service (BaaS)? Essentially we use the cloud, which is a collection of the aforementioned data centres, as the storage and the computing power required to manage the back processes rather than performing the backup with a centralised on-premise solution. BaaS allows system administrators to offload the maintenance and management to the service provider, thus freeing up their time to complete other tasks.
BaaS is quite often much more cost effective and reliable than an on-premise solution and negates issues such as network outages at the on-premise backup server site, server failure and physical security threats. By moving this functionality into the cloud you can greatly increase the agility of your business by having access to your data from anywhere on the planet with an internet connection. BaaS solutions can also be customised to utilise public, private or hybrid cloud environments depending on the needs of the organisation.
Data sovereignty is often a hot topic when it comes to moving core business functions into the cloud but most services now allow you to select geographically where your data is stored. This is perfect for data that by legislation must remain with the country of origin.
BaaS clients encrypt data while uplinking to your preferred storage location and once in the data centre, your data is hashed and sharded. Sharding a type of database partitioning that essentially splitting the data into hundreds of thousands if not millions of pieces then these being spread across the data centre. This means even if a data centre employee or hacker gains access to a hard drive only a tiny portion of your data is on there and it is encrypted and unreadable on its own.
It’s no surprise why many organisations are making the jump to the cloud and BaaS providers. This is certainly something worth investigating.
