How Often Should You Back Up Business Data? RPO Explained

One of the most common questions UK businesses ask their IT provider is: "How often should we be backing up our data?" The honest answer is that it depends — specifically, it depends on how much data you can afford to lose if something goes wrong.

That concept has a name in the IT world: Recovery Point Objective, or RPO. Understanding RPO helps you choose a backup frequency that matches your actual business risk, rather than guessing or over-spending on backup you don't need.

What Is RPO (Recovery Point Objective)?

Your Recovery Point Objective is the maximum amount of data — measured in time — that your business can tolerate losing after an incident.

Put simply:

• If your RPO is 24 hours, you're saying: "We can accept losing up to one day's worth of data."
• If your RPO is 1 hour, you're saying: "We can only afford to lose the last hour's worth of data."
• If your RPO is zero, you're saying: "We cannot lose any data at all" — which requires real-time replication.

Your RPO directly determines how often you need to back up. A 24-hour RPO means daily backups are sufficient. A 1-hour RPO means you need hourly backups or near-continuous data protection.

RPO vs RTO — What's the Difference?

These two terms are often confused but they measure different things:

• RPO (Recovery Point Objective) — how much data can you lose? (Measured backwards from the incident.)
• RTO (Recovery Time Objective) — how quickly must you be back up and running? (Measured forwards from the incident.)

Both are critical to your business continuity plan. RPO tells you how often to back up. RTO tells you how fast your recovery solution needs to work.

How to Determine Your RPO

Work through these questions for each system or data set:

1. How much data do you generate per hour/day? A busy e-commerce site creates far more transactional data per hour than a small consultancy.
2. What's the cost of recreating lost data? Can staff re-enter the data manually, or is it irreplaceable (e.g., customer communications, sensor data)?
3. What are your contractual or regulatory obligations? Some industries require specific backup frequencies (e.g., financial services, healthcare).
4. What's the financial impact of data loss? Calculate the revenue, productivity, and reputational cost of losing X hours of data.

Typical RPOs for UK SMEs

Here are common RPO targets by system type:

System	Typical RPO	Backup Frequency
Email (Microsoft 365)	4–24 hours	3x daily to daily
CRM / ERP	1–4 hours	Hourly to 4-hourly
Accounting software	4–24 hours	4-hourly to daily
File servers / documents	4–24 hours	4-hourly to daily
E-commerce / transactional DB	15 mins–1 hour	Near-continuous
Endpoint devices (laptops)	24 hours	Daily

Backup Frequency Options Explained

Daily Backups

The most common frequency for UK SMEs. A daily backup (usually run overnight) captures everything that changed during the business day. Suitable for most document-based workflows, email, and general file servers.

RPO: Up to 24 hours of data at risk.

Hourly Backups

For systems where losing a full day's data is unacceptable. Modern cloud backup solutions support hourly incremental snapshots with minimal performance impact.

RPO: Up to 1 hour of data at risk.

Near-Continuous / Real-Time Replication

For mission-critical systems like transactional databases, payment platforms, or healthcare records. Technologies like continuous data protection (CDP) or database replication capture every change as it happens.

RPO: Seconds to minutes of data at risk.

Weekly or Monthly Backups

Rarely appropriate as the primary backup frequency. However, weekly full backups are commonly used alongside daily incremental backups, and monthly archival backups provide long-term retention.

The True Cost of Getting RPO Wrong

Setting your RPO too high (backing up too infrequently) means you risk losing more data than your business can handle. Setting it too low (backing up too frequently) means you're paying for storage and infrastructure you don't need.

The sweet spot is a risk-based approach:

1. Identify your most critical systems and data.
2. Assign an RPO to each based on business impact.
3. Choose backup solutions and schedules that meet those RPOs.
4. Test your backups regularly to confirm they actually work.

Don't Forget to Test Your Backups

A backup that hasn't been tested is a backup you can't trust. Schedule regular restore tests — at least quarterly — to verify:

• Backups are completing successfully and on schedule
• Data can actually be restored (not just backed up)
• Restore times meet your RTO requirements
• Restored data is complete, uncorrupted, and usable

Many UK businesses discover their backups are broken only when they need them most. Don't be one of them.

Cloud Backup and RPO

Cloud backup solutions make it much easier to achieve tighter RPOs without investing in expensive on-site infrastructure. Services like Microsoft 365 backup solutions can run automated backups multiple times a day with retention policies that keep data for months or years.

For most UK SMEs, a cloud-first backup strategy provides the best balance of cost, reliability, and RPO flexibility.
