Backup Archives Content Comparison
Budget: $10 – $30 USD
I have two tar.gz full-backup archives—one roughly 3.4 GB, the other about 2.3 GB—and I need to know exactly how they differ.
The scope is a complete file-content comparison across every directory contained in both backups.
Core tasks
• Extract each archive to a safe working area (or use a tool that reads tar.gz directly).
• Generate checksums and compare every file to locate additions, deletions, or byte-level changes.
• Flag renamed or moved items so I can trace their history.
• Summarise directory-level differences (missing folders, size variations, etc.).
Deliverable
A clear, well-structured report—plain text, CSV, or HTML—that lists:
1. Files present in only one backup.
2. Files present in both but with differing content (include paths, sizes, and hashes).
3. Aggregate statistics showing how much of the data set has changed.
If you can also outline next steps for synchronising the backups, note that in a separate section; I’ll decide later whether to proceed with that.
Preferred tools include diff, rsync, Beyond Compare, or any reliable checksum utility, but feel free to use what you are most efficient with as long as the output is complete and easy to read.
Please let me know your approach and estimated turnaround time.
