Backup as a service (BaaS) is a way to backing up data that involves purchasing online backup and recovery services from a data backup provider rather than performing backup with a centralized, on-premises IT department. BaaS connects systems to a private, public or hybrid cloud managed by the outside provider.
Backup as a service is easier to manage than other offsite services. Instead of worrying about managing tapes or hard disks at an offsite location, data storage administrators can offload maintenance and management to the provider.
This service is mostly used when organizations run out of features to maintain their sites or need new upgrades or the resources in their premises for effective backup. Outsourcing backup and recovery to a service provider also keep data accessible or restorable from a remote location in case of an outage or failure.
Points to keep in mind when choosing a service:
• The first thing you want to be looking for is the ease of use, ease of deployment and speed of deployment. After all, when you look back at the root cause of why companies are looking at these solutions, a lot of it has to do with the management complexities of existing solutions.
• You have to look for technologies that are part of the solution that minimizes the impact of the network.
• Essentially after your initial full backup, are the technologies doing things like data deduplication or delta differencing or other block-based change mechanisms, so you’re not doing large volume copies of your backups over and over.
• These technologies are out there, but the key thing to look for is whether the incremental or deduplicated backups going over the networks after the initial pull are being deduplicated at your end of the deal or the service provider’s end of the deal.
• Another thing to look at is security. The bigger the organization, the more you are going to be concerned with things like access control lists, role-based authentication and role-based access to systems.
• For instance, let’s say you’re a company of 20 people and everyone is using this service, maybe you don’t want everyone to have the equivalent of root-level access to do resource.
• Be sure that you have some visibility into what’s actually happening, how much capacity you are using, what the performance looks like on a daily or weekly basis.
• Look for proof of infrastructure.
• And lastly, look for evidence of a company in technology stability.
Backing up and recovering data is a necessary discipline in all organizations but often considered costly, cumbersome and difficult to manage. Most backup problems happen overnight when you don’t have people watching them, meaning the backup window impacts production time and puts the business at risk of data loss. People and skills are the biggest cost and challenges in the backup.
