Backup & Recovery (Rsync/Tar/Dd)

Stop rsync from wrecking your remote space with invisible temp files

🧩 The Challenge

Everyone thinks rsync is smart enough to handle partial files, but if your connection drops halfway through a massive sync, you’re often left with a graveyard of partially-written debris on the destination. I’ve spent way too much time manually cleaning up broken file fragments after a late-night server migration went sideways.

💡 The Fix

You need to tell rsync to use a specific hidden directory for temporary files that gets cleaned up automatically if the transfer fails. It keeps your production storage clean and stops those half-baked files from causing app errors.

rsync -av --partial-dir=.rsync-tmp /local/data/ user@remote:/destination/

⚙️ Why It Works

Setting a partial directory tells rsync to stage incomplete chunks in a safe place until the transfer is fully verified, instead of dumping them directly into your live directory. Once the job succeeds, the bits are moved to their final home.

🚀 Pro-Tip: Add –delay-updates to that command if you want the final move to happen all at once, which prevents anyone from reading a file that’s still being written.
