PBS Stats

This program scans a directory tree for Proxmox Backup Server index files (.fidx and .didx), analyzes chunk deduplication, and reports statistics about chunk usage and file deduplication ratios.

Features

• Scans all .fidx and .didx files in a directory recursively
• Counts how often each chunk digest appears across all files
• Calculates deduplication ratio for each file (total chunks / unique chunks)
• Reports the top N most referenced chunks and the top N files with the highest deduplication ratio

Usage

scan_fidx [--top-chunks N] [--top-files N] <directory>

• --top-chunks N: Show the top N most referenced chunks (default: 50)
• --top-files N: Show the top N files with the highest deduplication ratio (default: 50)
• <directory>: Root directory to scan for .fidx and .didx files

Example

scan_fidx --top-chunks 100 --top-files 20 /path/to/datastore

This will print the 100 most referenced chunk digests and the 20 files with the highest deduplication ratio in the specified directory tree.
