When using this flag, rclone won't update mtimes of remote files if
they are incorrect as it would normally.
### --compare-dest=DIR ###
When using `sync`, `copy` or `move` DIR is checked in addition to the
destination for files. If a file identical to the source is found that
file is NOT copied from source. This is useful to copy just files that
have changed since the last backup.
You must use the same remote as the destination of the sync. The
compare directory must not overlap the destination directory.
See `--copy-dest` and `--backup-dir`.
### --config=CONFIG_FILE ###

connection to go through to a remote object storage system. It is
`1m` by default.
### --copy-dest=DIR ###
When using `sync`, `copy` or `move` DIR is checked in addition to the
destination for files. If a file identical to the source is found that
file is server side copied from DIR to the destination. This is useful
for incremental backup.
The remote in use must support server side copy and you must
use the same remote as the destination of the sync. The compare
directory must not overlap the destination directory.
See `--compare-dest` and `--backup-dir`.
### --dedupe-mode MODE ###
Mode to run dedupe command in. One of `interactive`, `skip`, `first`, `newest`, `oldest`, `rename`. The default is `interactive`. See the dedupe command for more information as to what these options mean.
