Accounting firms depend on continuous access to client files, QuickBooks data, Microsoft 365, payroll information, tax records, and working papers. A failed server, ransomware attack, accidental deletion, stolen laptop, or cloud-account compromise can interrupt work at the worst possible time.

Backup and disaster recovery are related but different. Backup preserves recoverable copies of information. Disaster recovery defines how systems, access, and business operations will be restored within an acceptable timeframe.

Identify the systems the firm cannot operate without

A recovery plan should begin with an inventory of critical applications, data, devices, and dependencies. This usually includes QuickBooks or other accounting platforms, Microsoft 365, file servers, cloud storage, line-of-business applications, network equipment, and employee workstations.

Each system needs a recovery priority, acceptable data-loss window, and target restoration time. SOS Computer Experts’ accounting IT support services help firms translate business priorities into technical recovery requirements.

Use multiple protected backup layers

No single backup should be trusted as the only recovery option. Critical information should have multiple copies, including at least one copy isolated from the production environment. Backups connected permanently to the same network can be encrypted or deleted during an attack.

A complete plan may include local recovery for speed, encrypted off-site copies for resilience, and separate cloud-to-cloud backup for Microsoft 365. Our backup and disaster recovery solutions are designed around monitored, automated protection.

Protect Microsoft 365 information

Email, OneDrive, SharePoint, and Teams information can be deleted accidentally, removed by a compromised user, or affected by retention settings that do not match the firm’s needs. A separate Microsoft 365 backup provides additional recovery points and more control over retention.

Identity security remains essential because backup does not prevent account compromise. Review Microsoft 365 security for accountants and bookkeepers for practical controls.

Back up QuickBooks and supporting files

QuickBooks protection should include the company file as well as attachments, templates, exports, supporting spreadsheets, and any server configuration required to restore operations. Backups should not depend on an employee remembering to copy a file manually.

Automated jobs need monitoring and alerts. Learn more about protecting QuickBooks and financial client data.

Test restoration—not just backup completion

A successful backup notification does not prove that the firm can recover. Restore tests verify that files are readable, credentials are available, applications open correctly, and the recovery process is understood. Tests also reveal missing dependencies before an emergency.

Results should be documented, including restoration times, issues found, and corrective actions. Critical systems should be tested regularly and after major technology changes.

Prepare for cyber incidents

Ransomware recovery requires more than restoring files. The firm must isolate affected devices, preserve evidence, reset compromised credentials, determine the attack path, rebuild clean systems, and validate security before reconnecting them. See our guide to cybersecurity risks facing accounting firms.

SOS Computer Experts’ cybersecurity services complement recovery planning with identity, endpoint, email, and network protection.

Document roles and communication

The recovery plan should identify decision-makers, technical contacts, software vendors, insurance contacts, and communication responsibilities. Employees should know how to report an incident and should not improvise changes that could spread damage or destroy evidence.

Local recovery support

Our managed IT services include monitoring, maintenance, backup oversight, security, and user support. Accounting firms south of the Fraser can also use our Surrey managed IT services for local expertise.
