> 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.
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}
