What Is Backup as a Service, and Why Do Accounting Firms Need It?

Backup as a service (BaaS) is a managed setup where a provider automatically copies your firm’s data to secure offsite storage and keeps it ready to restore. For accounting firms it is not optional: the FTC Safeguards Rule and IRS Publication 4557 expect you to recover client data after a failure or attack. Documented restore objectives are how you prove you can.

Key takeaways

BaaS automates backups, monitors them, and keeps an encrypted offsite copy ready to restore.

Backup protects the data; disaster recovery protects the practice. You need both.

The 3-2-1 rule: three copies, two media types, one offsite and isolated from your live system.

FTC Safeguards and IRS Pub 4557 expect a documented, tested recovery capability.

Verito has paid zero ransomware since 2016, because clean, isolated backups leave an attacker nothing to ransom.

What is backup as a service (BaaS)?

Backup as a service is a managed offering where a provider automatically backs up your firm’s data to secure offsite storage, monitors that the backups succeed, and keeps the data ready to restore on demand. You stop owning the scripts, the drives, and the question of whether last night’s backup actually ran.

The difference from a do-it-yourself backup is accountability. Backups run on a schedule, failures get caught and fixed, and the data sits encrypted in a location separate from your live system. For a firm whose entire work product is client financial data, that shift from “we think we have backups” to “backups are managed and verified” is the point.

What is the difference between backup and disaster recovery?

A backup is a copy of your data. Disaster recovery is the plan and the capability to get your firm running again after an outage, attack, or hardware failure. Backups answer whether you can get a file back. Disaster recovery answers how fast you can be working again. A serious firm needs both, with numbers attached.

Two terms make it concrete. RPO, the recovery point objective, is how much data you can afford to lose, measured in time. A daily backup means an RPO of up to 24 hours. RTO, the recovery time objective, is how long you can be down before you are back up. A managed service defines, documents, and tests both.

What are the types of backup?

The three common types are full, incremental, and differential. A full backup copies everything. An incremental copies only what changed since the last backup. A differential copies everything changed since the last full. Most managed services combine a periodic full with frequent incrementals to balance speed and storage.

Type	What it copies	Trade-off

Full	Everything, every time	Most complete, slowest and largest

Incremental	Changes since last backup	Fast and small, restore needs the chain

Differential	Changes since last full	Middle ground on speed and storage

Why do accounting firms specifically need managed backup?

Because tax and accounting firms hold exactly the data attackers want and regulators protect, and the rules expect you to recover it. Ransomware, a failed drive in busy season, or an accidental deletion can each halt a practice. Managed backup turns those events from a crisis into a restore.

The FTC Safeguards Rule (16 CFR Part 314) requires firms to protect client information and respond to security events, which means being able to recover data. IRS Publication 4557 directs firms to safeguard taxpayer data. Cyber-insurance underwriters now ask about backups directly, and a weak answer raises your premium or sinks the application.

What belongs on a CPA firm backup compliance checklist?

A defensible backup runs automatically, keeps at least one encrypted copy offsite and isolated, has documented RPO and RTO, is tested on a cadence, is monitored for failures, meets records-retention rules, and is named in your WISP. If you cannot check one of those boxes, that is where to start this week.

#	Check	Why it matters

1	Runs automatically on a schedule	Manual backups get skipped in busy season

2	A copy is offsite and isolated	Ransomware on your network should not reach it

3	Encrypted in transit and at rest	Required posture under FTC Safeguards / GLBA

4	Documented RPO and RTO	Defines tolerable data and time loss

5	Restores tested on a cadence	An untested backup is not a backup

6	Monitored, failures alert and get fixed	Silent failures cause most data loss

7	Retention meets records rules	Tax records have minimum retention periods

8	Named in your WISP	Your security plan should list these controls

DIY backup vs. managed backup: which should a firm use?

A do-it-yourself backup depends on someone remembering to run it, store it offsite, and test it. Managed backup makes those automatic and accountable, with monitoring that catches a failed backup before you need it. For a firm under FTC and IRS obligations, the managed route is the defensible one.

	DIY backup	Managed backup (BaaS)

Runs on schedule	If someone remembers	Automatic

Offsite copy	If someone sets it up	Built in

Failure detection	Often found too late	Monitored and alerted

Restore testing	Rarely done	On a regular cadence

Who is accountable	Whoever has time	The provider

How does Verito handle managed backup and recovery?

Verito’s managed backup runs automatically, keeps an encrypted copy in secure offsite data center storage, and is monitored so a failed backup gets corrected rather than discovered too late. Restore objectives are documented and validated on a cadence, so your RPO and RTO are numbers you can show an auditor, not hopes.

It sits on the same foundation as the rest of the platform: SOC 2 audited data centers, 100% uptime since 2016, and zero ransomware payments across that span, because backups an attacker cannot reach leave nothing to ransom. When you need a restore, a real person answers in under 60 seconds and 92% of issues resolve on the first touch. To map your backups against the checklist above, book a VeritComplete demo.
