DRaaS vs BaaS: recovery vs restore
Both protect you from data loss, but they answer different questions. BaaS asks “can I get my data back?” DRaaS asks “can I keep running?” Backup as a Service copies your data to the cloud so you can restore it. Disaster Recovery as a Service replicates whole systems so you can fail over and keep operating in minutes. The gap between them is measured in RTO and RPO.
What is Disaster Recovery as a Service?
Disaster Recovery as a Service (DRaaS) continuously replicates your servers, VMs, and applications to a standby cloud environment and provides orchestrated failover. When disaster strikes, you spin up in the recovery site in minutes — low recovery-time objective (RTO) and low recovery-point objective (RPO).
DRaaS is about business continuity: keeping operations running through an outage, ransomware event, or site loss. It includes runbooks, failover orchestration, and regular tested failovers — not just a copy of the data.
What is Backup as a Service?
Backup as a Service (BaaS) sends copies of your data to the cloud on a schedule, with retention and versioning. When you need it, you restore — files, databases, or systems — from those backups.
BaaS is about data protection and recoverability, and it's the foundation everyone needs. But restoring from backup takes time (hours to days for large systems), so RTO is higher. It answers “get the data back,” not “stay online.”
Side by side
DRaaS vs BaaS, compared
| DRaaS | BaaS | |
|---|---|---|
| Protects | Whole workloads (systems + data) | Data (files, databases, images) |
| Recovery method | Orchestrated failover to standby | Restore from backup copies |
| RTO (downtime) | Minutes | Hours to days |
| RPO (data loss) | Seconds to minutes | Since last backup (hours) |
| Goal | Business continuity — keep running | Data protection — get data back |
| Cost | Higher — standby compute + replication | Lower — storage + transfer |
| Best for | Critical systems that can't be down | Broad data protection & compliance retention |
Decision guide
When to choose each
Choose DRaaS when
- ▸Downtime on critical systems is unacceptable (minutes matter).
- ▸You need tested failover and orchestration, not just copies.
- ▸Ransomware or site loss would halt the business without failover.
Choose BaaS when
- ▸You need reliable, retained copies of data across the estate.
- ▸Longer recovery time is acceptable for most systems.
- ▸You want cost-effective, compliant data protection as a baseline.
DRaaS and BaaS are layers of one resilience strategy, not competitors. BaaS is the baseline — everything gets backed up with sensible retention. DRaaS is applied to the tier-1 systems that can't tolerate downtime. A sound approach backs up everything (BaaS) and adds orchestrated failover (DRaaS) for the workloads that must stay online — with recovery objectives set per tier.
Not sure which you need?
intSignal delivers managed backup and disaster recovery together — tiered RTO/RPO, tested failover, and off-region copies kept out of harm's way.
Frequently asked questions
What's the difference between DRaaS and BaaS?
BaaS (Backup as a Service) copies your data to the cloud so you can restore it — recovery takes hours to days. DRaaS (Disaster Recovery as a Service) replicates whole workloads for orchestrated failover in minutes. BaaS gets your data back; DRaaS keeps you running.
Do I need both DRaaS and BaaS?
Usually. BaaS is the baseline everyone needs for data protection and compliance retention. DRaaS is added for tier-1 systems that can't tolerate downtime. A good strategy backs up everything and adds failover for the critical workloads.
What are RTO and RPO?
RTO (recovery-time objective) is how quickly you must be back online; RPO (recovery-point objective) is how much data loss is acceptable, measured in time. DRaaS delivers low RTO and RPO (minutes); BaaS has higher RTO (restore time) and RPO (since the last backup).
Is DRaaS just cloud backup?
No. Backup copies data; DRaaS continuously replicates entire systems and provides tested, orchestrated failover so operations continue during an outage. DRaaS typically includes runbooks and regular failover tests, not just stored copies.
