Backup and Disaster Recovery Services: A Buyer's Guide

Backup and disaster recovery (BDR) services keep copies of your data and a tested plan to restore operations fast after an outage, hardware failure, or ransomware attack. A provider automates off-site or cloud backups and sets recovery targets (RTO and RPO) so you can resume business with minimal downtime and data loss.

What is backup and disaster recovery (BDR)?

Backup and disaster recovery, or BDR, pairs two things: keeping current copies of your data, and a documented plan to use those copies to resume operations quickly after a disruption. Backup is the copy. Disaster recovery is the plan and process to get running again after an outage, hardware failure, natural disaster, or cyberattack.

It matters because downtime and data loss are expensive and common. An hour of downtime costs most organizations over $100,000[1], and ransomware is now a leading cause of business disruption, contributing to reported cybercrime losses that topped $16 billion in a year[2]. Tested backups are often the difference between recovering and paying a ransom.

Backup vs disaster recovery: the difference

They are related but not the same. Backup is making and storing copies of files and systems. Disaster recovery is the broader plan, the people, processes, and technology, for restoring access to applications, data, and IT after an outage. You can have backups without a recovery plan, but you cannot recover quickly without both. The strongest setups combine automated backup with a tested DR plan.

Key terms: RTO, RPO, failover, and DRaaS

  • Recovery Time Objective (RTO). How fast you must be back up after an outage.
  • Recovery Point Objective (RPO). How much data, measured in time, you can afford to lose.
  • Failover and failback. Automatically switching to backup systems during an outage, then switching back.
  • Restore. Transferring backup data back to your primary systems.
  • DRaaS (Disaster Recovery as a Service). A managed, usually cloud-based, approach where a provider handles recovery for you.

Most businesses set different RTOs and RPOs per workload, with the tightest targets on the systems they cannot run without.

The 3-2-1 rule and backup types

The 3-2-1 rule is the backup standard: keep three copies of your data, on two different media types, with one copy off-site. It protects you when any single copy or location fails.

  • Full backup. A complete copy of all data.
  • Incremental backup. Only what changed since the last backup. Fast and storage-efficient.
  • Differential backup. Everything changed since the last full backup.

File-sync tools like Dropbox or Google Drive are useful storage but are not a substitute for a real BDR solution, because they do not provide tested, versioned recovery of whole systems.

Cloud vs on-premises backup

Cloud backup stores copies off-site with a provider, which protects against local disasters and is increasingly the default. On-premises backup keeps copies local for the fastest restores and tight data-residency needs. Many businesses use both: local copies for speed, cloud copies for off-site protection, which satisfies the 3-2-1 rule. BDR is closely tied to your broader cybersecurity and cloud setup.

What should be in a BDR plan?

  • Defined RTO and RPO for each critical workload
  • Automated, monitored backups following the 3-2-1 rule
  • Off-site or cloud copies protected against ransomware (immutable where possible)
  • A written, step-by-step recovery runbook
  • Regular recovery testing, at least once or twice a year

How to choose a backup and disaster recovery provider

  • Will they set and commit to RTO and RPO targets per workload?
  • Do they automate, monitor, and regularly test recovery, not just run backups?
  • Are backups immutable or air-gapped to survive ransomware?
  • Do they offer DRaaS with documented failover?
  • Can they show verified reviews and real recovery references?

BDR is usually part of a broader managed IT services plan. Shortlist three providers, ask each the same questions, and compare. To start from a vetted, merit-ranked list, browse providers by city in the Best IT MSP directory.

Frequently asked questions

What is the difference between backup and disaster recovery?
Backup is making and storing copies of your data. Disaster recovery is the broader plan and process for using those copies to restore applications, data, and IT operations after an outage. You need both: backups alone do not guarantee a fast, orderly recovery.
What is the 3-2-1 backup rule?
The 3-2-1 rule says to keep three copies of your data, stored on two different types of media, with one copy off-site. It protects you when any single copy or location fails, and it is the baseline standard for a sound backup strategy.
What are RTO and RPO?
Recovery Time Objective (RTO) is how quickly you must restore operations after an outage. Recovery Point Objective (RPO) is how much data, measured as a time window, you can afford to lose. Together they define how fast and how complete your recovery must be, and they drive your BDR design.
What is the difference between full, incremental, and differential backup?
A full backup copies all data. An incremental backup copies only what changed since the last backup, making it fast and storage-efficient. A differential backup copies everything changed since the last full backup. Most strategies combine periodic full backups with frequent incrementals.
What is DRaaS (disaster recovery as a service)?
DRaaS is a managed, usually cloud-based, approach where a provider hosts and manages your disaster recovery, including failover to their environment during an outage. It lets smaller businesses get enterprise-grade recovery without building and maintaining a second data center themselves.
Are Dropbox or Google Drive enough for backup?
No. File-sync and share services provide useful storage but are not a sufficient backup and disaster recovery solution. They do not deliver tested, versioned recovery of entire systems, immutable protection against ransomware, or defined RTO and RPO targets, which a real BDR solution provides.
How often should a disaster recovery plan be tested?
Most experts recommend testing your disaster recovery plan at least once or twice a year, and after any major change to your systems. Untested recovery plans are the most common reason recoveries fail when a real disaster hits.
