Symptom & Impact

Backup jobs fail partially, leaving inconsistent or incomplete dataset copies.

Environment & Reproduction

Happens when destination permissions, ACLs, or remote account rights are insufficient.

Root Cause Analysis

Rsync process cannot read source files or write metadata to target path.

Quick Triage

Determine whether errors are source-read, destination-write, or metadata preservation failures.

Step-by-Step Diagnosis

Review rsync exit codes, file ACLs, mount options, and user identity context.

Solution – Primary Fix

Adjust ownership and ACLs, ensure target path write access, and rerun rsync with proper flags.

Solution – Alternative Approaches

Use dedicated backup service account with controlled sudo rights for privileged paths.

Verification & Acceptance Criteria

Rsync exits with code 0 and post-run file integrity checks pass.

Rollback Plan

Remove partial destination snapshot and restore last successful backup set.

Prevention & Hardening

Preflight permission checks and immutable backup retention policies reduce silent drift.

Related Errors & Cross-Refs

rsync error code 13 permission denied; failed to set times; operation not permitted.
