On this page
backdown dupes [OPTIONS]

Options

--min-size <MIN_SIZE>
Ignore files smaller than this (e.g. 100K, 1M, 2G). Default: 1M.
--limit <LIMIT>
How many groups to list. Default: 20.
--json
Print it as JSON, for scripts.
--jobs <JOBS>
Readers per device; 1 suits spinning disks, raise it for SSDs. Default: 1.
--retry-errors
Retry files that failed to read last time.

Also takes the global options --db and --local.

Good to know

Hardlinks count once. Only fully hashed files are grouped, and dupes runs hash first.
