What is Backup as a Service (BaaS)?
Backup as a Service (BaaS) is a cloud-delivered model in which a vendor manages the infrastructure, scheduling, and storage required to back up an organization's data. It covers on-premises systems, cloud workloads, and SaaS applications, and supports recovery in the event of data loss, ransomware, or disaster.
What it does
BaaS products automate the process of copying data to a remote, vendor-managed location on a defined schedule. Core functions include:
Scheduling and running backup jobs for servers, endpoints, databases, and SaaS apps such as Microsoft 365
Storing encrypted backup copies in cloud or hybrid storage
Enabling point-in-time restores so teams can recover data from a specific moment before an incident
Monitoring backup job success and failure, and alerting when jobs miss their window
Supporting disaster recovery by replicating environments or configurations that can be spun up quickly
Some products in this category also handle SaaS configuration backup, meaning they capture the settings and structure of cloud environments, not just file data.
Why teams buy it
Teams buy BaaS to remove the burden of managing backup hardware and software in-house. Key drivers include:
Ransomware recovery. Immutable or encrypted offsite copies give teams a clean restore point after an attack.
SaaS data protection. Cloud providers such as Microsoft operate on a shared responsibility model. They keep the platform running, but customers are responsible for their own data. BaaS fills that gap for M365, Google Workspace, and similar platforms.
Compliance. Regulations such as HIPAA, GDPR, and SOC 2 require documented data retention and recovery capabilities.
MSP use cases. Managed service providers use BaaS platforms to monitor and manage backup jobs across many client environments from a single console.
What to look for
Confirm the product can meet your targets before an incident, not after.
Recovery time and recovery point objectives (RTO/RPO).
Coverage breadth. Check whether the product covers on-premises servers, IaaS, SaaS apps, and cloud configurations, or only a subset.
Immutability and encryption. Backups should be encrypted in transit and at rest, and ideally write-once to prevent tampering.
Monitoring and alerting. Silent backup failures are common. Look for job-level visibility and proactive alerts.
Restore testing. Some platforms automate restore verification so teams know backups are actually usable.
Multicloud support. If your data spans AWS, Azure, and GCP, confirm the product handles all three.
Common confusions
BaaS is often confused with Disaster Recovery as a Service (DRaaS). BaaS focuses on copying and retaining data. DRaaS goes further by replicating entire environments and orchestrating failover so systems stay available during an outage. Some vendors offer both under one platform.
BaaS is also distinct from Data Loss Prevention (DLP), which sits in the same Data Protection parent category. DLP prevents unauthorized data from leaving the organization. BaaS ensures data can be recovered after it is lost or corrupted.
Data Protection is the set of technologies and practices that prevent unauthorized access, loss, or misuse of sensitive data across an organization's systems, endpoints, and cloud environments.
Data Security Posture Management (DSPM) is a category of security tools that discover, classify, and assess the risk of sensitive data across cloud and on-premises environments.
Data Access Governance (DAG) is a set of controls and tooling that defines who can access which data, enforces those rules, and records what actually happened.
Frequently asked questions
What is Backup as a Service and how does it work?
Backup as a Service is a subscription model where a vendor manages cloud storage and software to back up your data automatically. You configure schedules and retention policies, and the vendor handles the infrastructure. When you need to recover data, you restore from a copy stored in the vendor's cloud.
Does Microsoft 365 need a third-party backup solution?
Microsoft operates on a shared responsibility model. It protects the platform itself but does not guarantee recovery of individual user data deleted by accident, ransomware, or a malicious insider. A third-party BaaS product fills that gap by keeping independent copies of mailboxes, files, and other M365 data.
What is the difference between BaaS and DRaaS?
BaaS copies and stores data so it can be restored after loss or corruption. DRaaS replicates entire systems and can fail over workloads to keep services running during an outage. Some platforms combine both capabilities, but they address different recovery objectives.
How do BaaS products protect against ransomware?
Most BaaS products store backups in immutable storage, meaning the backup copies cannot be encrypted or deleted by ransomware that reaches your primary environment. Encrypted, offsite copies give teams a clean restore point that predates the attack.
