Backup-as-a-Service (BaaS) and Cloud Backups
While Backup-as-a-Service (BaaS) and Cloud Backup can be used as interchangeable terms, it is important to note that each is very different from Recovery-as-a-Service (RaaS/DRaaS), which can also be referred to as Cloud DR. However, BaaS and RaaS can both play an important role in a thorough business continuity plan or process.
A common misunderstanding is what Backup-as-a-Service (BaaS) is compared to Recovery-as-a-Service (RaaS), which is also known as Disaster-Recovery-as-a-Service (DRaaS).
BaaS and Cloud Backups refer to data and file recovery performed remotely over the internet, through which cloud IaaS or cloud storage is used to manage and restore the data. BaaS and Cloud Backup can also be called online backup or remote backup. This is normally done for a monthly “utility” fee.
Recovery-as-a-Service (RaaS), compared to cloud backups, includes the recovery of not only your files and databases, but also your applications. This means that after a disaster hits, you are essentially given a working system, as opposed to just the working parts that still need to be reassembled.
RaaS provides application backup and recovery for either your entire IT infrastructure or only select mission-critical applications and systems, in a previously agreed upon timeframe.
Backups are usually performed once per day/night and will not deliver recovery point objectives or recovery time objectives of minutes, but recovers from the last point in time in which a backup was made. Enterprise disaster recovery options such as RaaS or DRaaS offer RTO and RPO options with various snapshot options to fail back over to in case the most recent point in time is corrupted. Also, disaster recovery solutions offer reverse replication to ensure the application is protected after declaration by replicating back to the source site, whereas BaaS only replicates from the source site.
These are important distinctions to note when planning your disaster recovery and business continuity plans.
