Finds duplicate filesystem extents and optionally schedule them for deduplication. An extent is small part of a file inside the filesystem. On some filesystems one extent can be referenced multiple times, when parts of the content of the files are identical. More information:
  • Search for duplicate extents in a directory and show them:
    duperemove -r {{path/to/directory}}
  • Deduplicate duplicate extents on a Btrfs or XFS (experimental) filesystem:
    duperemove -r -d {{path/to/directory}}
  • Use a hash file to store extent hashes (less memory usage and can be reused on subsequent runs):
    duperemove -r -d --hashfile={{path/to/hashfile}} {{path/to/directory}}
  • Limit I/O threads (for hashing and dedupe stage) and CPU threads (for duplicate extent finding stage):
    duperemove -r -d --hashfile={{path/to/hashfile}} --io-threads={{N}} --cpu-threads={{N}} {{path/to/directory}}
