PunkBackup v1.7.8
Improvements
- Second-copy (mirror) sync is significantly faster. Measured on real data: syncing to a second USB drive was spending ~81% of its time on a database confirmation after every single file, not on copying or verifying content. That confirmation is now batched (every 25 files instead of every file), cutting real sync time by 4-5x with copying and hash verification completely unchanged -- same protection against corrupted copies as before. Safe to interrupt at any point, same as always.
