Work in progress\n\n# hsnap\nRemove files (\"trim\") that have duplicates elsewhere.\n\nBy using space-savvy hash snapshots, *hsnap* can perform deduplication across\nmultiple filesystems without having them all accessed at the same time.\n\nIn a nutshell:\n- Run ```hsnap create``` on some NAS\n- Copy the generated ```.hsnap``` file on your localhost, rename it ```nas.hsnap```\n- Run ```hsnap trim nas.hsnap -delete``` to remove all local files that have duplicates\non the NAS\n\nGenerated .hsnap files are small: 6GB of results in a ~360k hsnap file...\n\n... and fast to generate: on a quadcore+SSD, it takes around 2min to hash said 6GB.\n\nA Synology NAS hashes 100GB within 26min.\n\nDuplication finding uses file size and SHA-1 hashing comparison, so don't expect security, \nbut fair level of guarantee that only duplicates are found.\n\n## Usage\n    \n    hsnap help\n    hsnap \u003ccmd\u003e -help\n\nRunning on a NAS without screen/tmux and forgetting about it:\n\n    nohup hsnap... \u003c/dev/null \u003ehsnap.log 2\u003e\u00261 \u0026\n\nExploring easily an info result:\n\n    hsnap trim nas.hsnap | less -R\n\n## TODO\n- be able to resume a hashing, by leveraging file existence,\n- test extensively,\n- dedup without trimming (perhaps, as fdupes does it already quite well),\n- cleanup the code.\n- Buffer .hsnap while creating in memory...\n\n## Inspiration\n- [mathieuancelin/duplicates](https://github.com/mathieuancelin/duplicates/blob/master/duplicates.go)\n- [SeeSpotRun
