recovery (DR) in clinical trials. It ensures the protection of critical study data, prevents data loss, guarantees business continuity, and safeguards compliance with regulatory requirements such as FDA 21 CFR Part 11, ICH GCP, EMA, CDSCO, and WHO guidance. This SOP aims to maintain integrity, availability, and accessibility of data throughout the trial lifecycle.

Scope

This SOP applies to all electronic systems used in clinical trials, including but not limited to: Clinical Data Management Systems (CDMS), Electronic Data Capture (EDC), safety databases, pharmacovigilance systems, laboratory information systems (LIMS), and electronic Trial Master File (eTMF). It covers routine data backup schedules, offsite storage, restoration testing, emergency recovery procedures, and documentation requirements.

Responsibilities

• System Owner: Ensures backup and disaster recovery procedures are implemented and tested.
• Data Manager: Verifies successful execution of backups and coordinates restoration testing.
• IT Administrator: Configures, maintains, and monitors backup systems, ensuring security and encryption.
• Principal Investigator (PI): Ensures essential site-level data is backed up and retrievable.
• Sponsor/CRO: Oversees global backup strategies and compliance with regulatory standards.
• QA Officer: Audits backup and recovery processes to confirm compliance and readiness for inspection.

Accountability

The sponsor and system owner are accountable for ensuring that robust, validated backup and recovery strategies are in place and documented. The IT administrator is accountable for technical execution and log maintenance, while QA ensures independent oversight.

Procedure

1. Backup Planning
Define critical systems requiring backups (CDMS, EDC, safety, LIMS, eTMF).
Establish backup frequency: daily incremental and weekly full backups.
Prepare a Backup and Recovery Plan (BRP) reviewed annually by QA and sponsor.

2. Backup Execution
Perform automated backups through validated backup tools with encryption enabled.
Store copies in three locations: onsite, secure offsite facility, and encrypted cloud repository.
Maintain logs of each backup run, recording date, time, system, and outcome (Annexure-1).

3. Backup Verification
Review system-generated reports daily to confirm successful backups.
Randomly verify 10% of backups monthly by restoring files in a test environment.
Document verification results in Backup Verification Log (Annexure-2).

4. Disaster Recovery Preparation
Identify potential disaster scenarios (power failure, server crash, cyberattack, natural disaster).
Prepare a Disaster Recovery Plan (DRP) that defines roles, escalation matrix, and recovery time objectives (RTO).
Train staff annually on DRP procedures.

5. Disaster Recovery Execution
Initiate DR procedures within 24 hours of a critical system failure.
Restore data from the most recent validated backup.
Document recovery activity in Disaster Recovery Log (Annexure-3).
Conduct root cause analysis and implement CAPA for failures.

6. Periodic Testing
Conduct full disaster recovery simulations at least annually.
Record outcomes, deviations, and corrective actions.

7. Documentation
Maintain logs of all backups, verifications, and recovery attempts.
File records in TMF and ISF as applicable.

8. Archiving
Retain backup and DR logs for a minimum of 15 years or as per regulatory requirements.
Ensure archived copies are secure, access-controlled, and retrievable.
