to-check gives you the number of files still to be checked, e.g.
0/1 means 0 of a total of 1 files in the queue still need to be checked.
During a normal transfer with, let's say 42 files,
to-check will basically count down from 42 to 0 (
rsync is done syncing.
Note that for large amounts of files, the last number in
to-check may also grow since
rsync doesn't queue all files at once (
to-check=2/56). That's because it uses a recursion algorithm:
Beginning with rsync 3.0.0, the recursive algorithm used is now an incremental scan that uses much less memory than before and begins the transfer after the scanning of the first few directories have been completed.
To disable this behavior add the
Note that in newer releases of rsync (3.1.0), the label has been changed to
ir-chk to indicate incremental recursive progress (ie: the default) and
to-check to indicate non incremental recursive progress (ie: with the
