Managed IT Services for Backup and Disaster Recovery

Every enterprise has backups. Far fewer have a recovery plan they’d bet the business on. The gap between the two usually stays hidden until a ransomware note appears, a storage array fails or a cloud tenant is wiped. By then, the only question that matters is how fast clean systems and data can come back.

That’s why more enterprises are moving to managed IT services for backup and disaster recovery. Many organizations treat backup as a nightly job and disaster recovery as a binder on a shelf. A managed provider instead runs protection, monitoring, testing and recovery as one continuous service, measured against recovery targets the business has agreed to.

This guide covers what an enterprise-grade managed backup and disaster recovery service should include, how to size recovery targets and storage, and what Canadian and US guidance expects. It also shows how to tell a capable provider from one that only sells software licences. It’s written for digital transformation and IT leaders who need data protection that holds up under real pressure.

What Managed Backup and Disaster Recovery Means

Managed IT services for backup and disaster recovery combine three responsibilities under one provider:

Protecting data with secure, monitored backups
Restoring systems quickly through planned and tested failover
Keeping the business running through documented continuity procedures

The provider handles the day-to-day work and reports on it. The business decides the recovery targets.

The three layers are related but not interchangeable:

Layer	Question it answers	Typical measure	Example
Backup	Can we get the data back?	Recovery point objective (RPO): how much data can be lost	Restoring a deleted SharePoint library from last night’s copy
Disaster recovery	Can we get the systems running again?	Recovery time objective (RTO): how long recovery can take	Failing over an ERP platform to a replicated environment
Business continuity	Can the business keep operating meanwhile?	Maximum tolerable disruption to critical processes	Switching order processing to a manual workflow during an outage

Enterprise backup solutions only cover the first row. A managed service is valuable because it connects all three.

Why Backups Fail When They’re Needed Most

Backups rarely fail because nobody bought them. They fail because attackers target them, because no one tested them, or because recovery takes far longer than anyone planned.

Ransomware is the clearest example. CISA and its partners publish a joint guide called the #StopRansomware Guide. It warns that “many ransomware variants attempt to find and subsequently delete or encrypt accessible backups.” It recommends that organizations “maintain offline, encrypted backups of critical data” and “regularly test the availability and integrity of backups in a disaster recovery scenario” (CISA).

The impact shows up in recovery data. Sophos’s State of Ransomware 2025 report found that only 54% of organizations whose data was encrypted used backups to restore it, the lowest rate in six years. The average cost to recover from an attack was $1.53 million (Sophos).

There’s a positive signal too. In the same report, 53% of victims fully recovered within a week, up from 35% a year earlier. Recovery is getting faster for organizations that prepare.

The Recovery Math Most Plans Skip

Two calculations show whether a backup strategy can actually meet its recovery targets.

How long will a full restore take?

Restore time depends on how much data has to move and how fast it can move:

Restore time = data size in bytes × 8 ÷ connection speed in bits per second

For 10 TB of data:

At 1 Gbps: 10,000,000,000,000 bytes × 8 ÷ 1,000,000,000 bits per second = 80,000 seconds, or about 22 hours.
At 10 Gbps: 8,000 seconds, or about 2.2 hours.

These are theoretical maximums. Real restores are usually slower once storage speed, compression and verification are factored in.

So if the business has agreed to a four-hour RTO for a 10 TB system, a 1 Gbps link to a remote backup store can’t meet it. That’s why enterprise disaster recovery services protect critical systems with replication, local recovery copies and orchestrated failover, rather than relying on a full restore from scratch.

How much backup storage do you need?

Retention policy drives storage cost. Take an environment with 20 TB of primary data, where about 3% changes each day, with backups kept for 30 days:

One full backup: 20 TB
Thirty daily incremental backups: 30 × 0.6 TB = 18 TB
Total per backup copy: 38 TB

Good practice keeps more than one backup copy in different locations. A design with two backup copies therefore needs about 76 TB of raw backup capacity before compression and deduplication. A managed provider should show you this math before you sign, not after the first storage invoice.

The Architecture of a Recoverable Backup

Government guidance on both sides of the border points to the same core design.

Keep three copies on two media types, with one offsite. The Canadian Centre for Cyber Security recommends the 3-2-1 rule: “3 copies of your information (1 original and 2 backups),” on 2 different media types, with 1 copy offsite. It also recommends keeping at least one backup offline, disconnected from the network (Cyber Centre).

Make backups tamper-resistant. CISA advises enabling “delete protection or object lock on storage resources often targeted in ransomware attacks.” It also notes that some cloud vendors offer immutable storage.

Prepare clean rebuild points. CISA recommends maintaining and regularly updating “golden images” of critical systems. It also recommends keeping offline backups of infrastructure templates so resources can be redeployed quickly.

Protect SaaS data separately. Microsoft 365, Google Workspace and other SaaS platforms hold critical business data. Backing them up to an independent location means a compromised admin account or a mass deletion can’t take the only copy with it.

Encrypt everything. The Cyber Centre recommends encrypting sensitive data and applying security controls, such as encryption, to storage devices and to cloud or vendor backups.

Matching Recovery Targets to Business Impact

Not every system needs the same protection. A tiered approach puts investment where downtime hurts most.

Tier	Example systems	Illustrative RTO	Illustrative RPO	Protection approach
Tier 1: Mission-critical	ERP, payment platforms, customer-facing applications	Minutes to a few hours	Minutes	Continuous replication, orchestrated failover, immutable copies
Tier 2: Business-essential	Email, collaboration, CRM, file services	Within a business day	A few hours	Frequent backups, SaaS backup, tested restores
Tier 3: Supporting	Archives, development and test environments	Several days	24 hours	Daily backups with longer retention

These targets are illustrative. The right numbers come from a business impact analysis. They should be agreed with each system’s owner, then tested against reality.

What Canadian and US Requirements Expect

Recovery capability is increasingly a compliance requirement, not just good practice.

Healthcare (US): the HIPAA Security Rule requires covered entities to maintain three plans: a data backup plan that creates “retrievable exact copies” of electronic protected health information, a disaster recovery plan to “restore any loss of data,” and an emergency mode operation plan. It also covers periodic testing of those plans (45 CFR 164.308).
Privacy (Canada): under PIPEDA, organizations must keep records of every breach of security safeguards for two years (OPC). Backup and recovery logs often become part of that evidence trail.
Guidance (Canada and US): the Cyber Centre and CISA both recommend offline or immutable backups, encryption and routine restore testing.

A managed provider should map your backup and recovery evidence to the frameworks you report against, so audit preparation doesn’t become a separate project.

How to Evaluate a Managed Backup and DR Provider

Strong IT infrastructure management partners can answer these questions with evidence:

What RTO and RPO will you commit to for each tier, and how do you prove them?
Can you show a redacted restore test report from the past quarter?
How is backup storage isolated from our production accounts and network?
Which SaaS platforms do you back up, and how granular is recovery?
What’s your process when ransomware reaches production systems?
Which certifications cover your own operations, such as ISO 27001 or SOC 2?
How quickly can you protect our most critical systems after signing?

Frequently asked questions

How much backup storage does an enterprise really need?

It depends on data volume, daily change rate, retention period and the number of backup copies. For example, 20 TB of primary data with a 3% daily change rate, kept for 30 days, needs about 38 TB per backup copy, or about 76 TB for two copies. That’s before compression and deduplication.

Can a 10 TB system be restored within four hours?

Not with a full restore over a 1 Gbps connection. That takes about 22 hours at theoretical line speed. Meeting a four-hour target for a system that size usually requires replication, local recovery copies or orchestrated failover, rather than restoring everything from scratch.

What is an immutable backup, and why does it matter for ransomware?

An immutable backup can’t be changed or deleted for a set retention period, even by someone with administrator access. That matters because CISA warns that many ransomware variants actively look for backups to delete or encrypt.

Do Canadian organizations need to keep backups in Canada?

It depends on the data and the sector. The Canadian Centre for Cyber Security recommends keeping medium and high sensitivity data within Canada when using managed services. Confirm where every backup copy is stored before signing with a provider.

What does HIPAA require for backup and disaster recovery?

The HIPAA Security Rule requires covered entities to maintain three plans: a data backup plan that creates retrievable exact copies of electronic protected health information, a disaster recovery plan to restore lost data, and an emergency mode operation plan. Periodic testing and revision of these plans is also addressed.

How soon can AppStudio start protecting our critical systems?

Critical systems can usually be protected within days of starting, with the full rollout completed in 2 to 4 weeks, depending on scope.

Make Recovery a Measured Capability

What separates a backup from a recovery is proof. Some enterprises define recovery targets, isolate their backups, test regularly and hand day-to-day operations to an accountable partner. They turn data protection into a capability they can measure. To find out whether your current backups would meet your recovery targets under pressure, talk to AppStudio about a recovery readiness assessment.
