Switched from talking about "unchanged" files to "identical" files. I found out the hard way that the rclone copy will overwrite newer files. Looking at posts in the rclone forum, this is a common experience. The docs for copy have referred to "unchanged" files. This is ambiguous because it intuitively introduces a sense of chronology, but chronology is irrelevant. Rclone only "cares" about difference, not change.

Use: "sync source:path dest:path",
|
|
Short: `Make source and dest identical, modifying destination only.`,
|
|
Long: `
|
|
Sync the source to the destination, changing the destination
|
|
only. Doesn't transfer files that are identical on source and
|
|
destination, testing by size and modification time or MD5SUM.
|
|
Destination is updated to match source, including deleting files
|
|
if necessary (except duplicate objects, see below).
|
|
|
|
**Important**: Since this can cause data loss, test first with the
|
|
` + "`--dry-run` or the `--interactive`/`-i`" + ` flag.
|
|
|
|
rclone sync -i SOURCE remote:DESTINATION
|
|
|
|
Note that files in the destination won't be deleted if there were any
|
|
errors at any point. Duplicate objects (files with the same name, on
|
|
those providers that support it) are also not yet handled.
|
|
|
|
It is always the contents of the directory that is synced, not the
|
|
directory so when source:path is a directory, it's the contents of
|
|
source:path that are copied, not the directory name and contents. See
|
|
extended explanation in the ` + "`" + `copy` + "`" + ` command above if unsure.
|
|
|
|
If dest:path doesn't exist, it is created and the source:path contents
|
|
go there.
|
|
|
|
**Note**: Use the ` + "`-P`" + `/` + "`--progress`" + ` flag to view real-time transfer statistics
|
|
|
|
**Note**: Use the ` + "`rclone dedupe`" + ` command to deal with "Duplicate object/directory found in source/destination - ignoring" errors.
