📦 Efficient file syncing for massive datasets? Forget classic rsync!
⚡ #BLAKE3 hashes instead of timestamps – hash 70GB in just ~20 seconds thanks to multithreading across all CPU cores
#DevOps #Linux #SysAdmin #OpenSource #FileSync
📊 Algorithm comparison for 70GB:
- BLAKE3: ~20 seconds
- MD5: ~1.5 minutes
- SHA256: ~4.5 minutes
🔍 The trick: Create a hash baseline, compare with `comm -13`, then use `rsync --files-from` to transfer only actually changed files
