Problem
A backup system reports job success when files were staged to a local cache but the cache-to-archive upload never completed.
Solution
Root Cause / Diagnostic:
Hybrid cloud backup software often stages files to a local staging SSD cache and immediately issues a "Job Completed" status to the user interface. If the background upload thread stalls due to WAN disconnection, bandwidth limits, or API rate limiting, the creator believes the backup is secure when it exists only on temporary local cache.
Actionable Fix:
1. Two-Tier Status Notification Configuration: Configure backup software notifications to report success only after cloud API acknowledges 100% committed upload completion (e.g., S3 ETag match).
2. Staging Queue Monitoring: Set up automated alerts to flag any files lingering in the local cache staging folder for longer than 6 hours.
3. Cloud Object Verification: Log into the cloud storage web console or use CLI (`aws s3 ls` / `rclone ls`) to confirm camera files are physically present in the remote bucket.
Pro Tip:
Never trust a "Backup Complete" notification until you verify the files actually uploaded to the cloud; many tools mark jobs done the second files hit a local staging cache.
