Local Filesystem

Local paths are specified as normal filesystem paths, eg /path/to/wherever, so

rclone sync /home/source /tmp/destination

Will sync /home/source to /tmp/destination

These can be configured into the config file for consistencies sake, but it is probably easier not to.

Modified time

Rclone reads and writes the modified time using an accuracy determined by the OS. Typically this is 1ns on Linux, 10 ns on Windows and 1 Second on OS X.

Filenames

Filenames are expected to be encoded in UTF-8 on disk. This is the normal case for Windows and OS X.

There is a bit more uncertainty in the Linux world, but new distributions will have UTF-8 encoded files names. If you are using an old Linux filesystem with non UTF-8 file names (eg latin1) then you can use the convmv tool to convert the filesystem to UTF-8. This tool is available in most distributions’ package managers.

If an invalid (non-UTF8) filename is read, the invalid characters will be replaced with the unicode replacement character, ‘�’. rclone will emit a debug message in this case (use -v to see), eg

Local file system at .: Replacing invalid UTF-8 characters in "gro\xdf"

Long paths on Windows

Rclone handles long paths automatically, by converting all paths to long UNC paths which allows paths up to 32,767 characters.

This is why you will see that your paths, for instance c:\files is converted to the UNC path \\?\c:\files in the output, and \\server\share is converted to \\?\UNC\server\share.

However, in rare cases this may cause problems with buggy file system drivers like EncFS. To disable UNC conversion globally, add this to your .rclone.conf file:

[local]
nounc = true

If you want to selectively disable UNC, you can add it to a separate entry like this:

[nounc]
type = local
nounc = true

And use rclone like this:

rclone copy c:\src nounc:z:\dst

This will use UNC paths on c:\src but not on z:\dst. Of course this will cause problems if the absolute path length of a file exceeds 258 characters on z, so only use this option if you have to.

Normally rclone will ignore symlinks or junction points (which behave like symlinks under Windows).

If you supply --copy-links or -L then rclone will follow the symlink and copy the pointed to file or directory.

This flag applies to all commands.

For example, supposing you have a directory structure like this

$ tree /tmp/a
/tmp/a
├── b -> ../b
├── expected -> ../expected
├── one
└── two
    └── three

Then you can see the difference with and without the flag like this

$ rclone ls /tmp/a
        6 one
        6 two/three

and

$ rclone -L ls /tmp/a
     4174 expected
        6 one
        6 two/three
        6 b/two
        6 b/one

Restricting filesystems with --one-file-system

Normally rclone will recurse through filesystems as mounted.

However if you set --one-file-system or -x this tells rclone to stay in the filesystem specified by the root and not to recurse into different file systems.

For example if you have a directory hierarchy like this

root
├── disk1     - disk1 mounted on the root
│   └── file3 - stored on disk1
├── disk2     - disk2 mounted on the root
│   └── file4 - stored on disk12
├── file1     - stored on the root disk
└── file2     - stored on the root disk

Using rclone --one-file-system copy root remote: will only copy file1 and file2. Eg

$ rclone -q --one-file-system ls root
        0 file1
        0 file2
$ rclone -q ls root
        0 disk1/file3
        0 disk2/file4
        0 file1
        0 file2

NB Rclone (like most unix tools such as du, rsync and tar) treats a bind mount to the same device as being on the same filesystem.

NB This flag is only available on Unix based systems. On systems where it isn’t supported (eg Windows) it will be ignored.

Standard Options

Here are the standard options specific to local (Local Disk).

--local-nounc

Disable UNC (long path names) conversion on Windows

  • Config: nounc
  • Env Var: RCLONE_LOCAL_NOUNC
  • Type: string
  • Default: “”
  • Examples:
    • “true”
      • Disables long file names

Advanced Options

Here are the advanced options specific to local (Local Disk).

Follow symlinks and copy the pointed to item.

  • Config: copy_links
  • Env Var: RCLONE_LOCAL_COPY_LINKS
  • Type: bool
  • Default: false

Don’t warn about skipped symlinks. This flag disables warning messages on skipped symlinks or junction points, as you explicitly acknowledge that they should be skipped.

  • Config: skip_links
  • Env Var: RCLONE_LOCAL_SKIP_LINKS
  • Type: bool
  • Default: false

--local-no-unicode-normalization

Don’t apply unicode normalization to paths and filenames (Deprecated)

This flag is deprecated now. Rclone no longer normalizes unicode file names, but it compares them with unicode normalization in the sync routine instead.

  • Config: no_unicode_normalization
  • Env Var: RCLONE_LOCAL_NO_UNICODE_NORMALIZATION
  • Type: bool
  • Default: false

--local-no-check-updated

Don’t check to see if the files change during upload

Normally rclone checks the size and modification time of files as they are being uploaded and aborts with a message which starts “can’t copy - source file is being updated” if the file changes during upload.

However on some file systems this modification time check may fail (eg Glusterfs #2206) so this check can be disabled with this flag.

  • Config: no_check_updated
  • Env Var: RCLONE_LOCAL_NO_CHECK_UPDATED
  • Type: bool
  • Default: false

--one-file-system

Don’t cross filesystem boundaries (unix/macOS only).

  • Config: one_file_system
  • Env Var: RCLONE_LOCAL_ONE_FILE_SYSTEM
  • Type: bool
  • Default: false

Share and Enjoy.
