DUP-CHECK(1)

📦 version 2.0, in nixos 26.05, nixpkgs unstable

💖 dup-check(1) 💖

okay so bestie, welcome to dup-check, section 1 of the General Commands Manual — she's a real one and she's here to do exactly one (1) job: check that your snapshot isn't lying to you 🫶

✨ NAME ✨

dup-check — check snapshot consistency. that's it. that's the whole vibe check 💅

🌸 SYNOPSIS 🌸

dup-check [-v] [-k keyfile] [-r repo] name

🦋 DESCRIPTION 🦋

so dup-check performs an internal consistency check on a snapshot with the given name. like, it's literally going through the receipts 🔍

the way it does this: it recalculates the hash of all blocks contained in the snapshot and checks whether the recorded hash of each block matches the actual hash. lowkey iconic detective behaviour ngl 🕵️‍♀️✨

and if a corrupt block gets detected? the hash of that block gets printed on standard output. no cap, that's your little red flag 🚩 bestie will see it.

🎀 OPTIONS 🎀

  • -k keyfile — path to encryption key. give her the key, she'll handle it 🔑
  • -r repo — path to the dedup repository. by default the current working directory is used. so if you don't point her somewhere, she's just gonna look around where she's standing 🙈
  • -v — enable verbose mode. she'll yap more. we love a chatty queen 💬👑
