--- title: "Local Filesystem" description: "Rclone docs for the local filesystem" date: "2014-04-26" --- 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](https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx#maxpath) 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](https://github.com/ncw/rclone/issues/261). 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. ### Symlinks / Junction points 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. Note that this flag is incompatible with `-links` / `-l`. 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 ``` #### --links, -l Normally rclone will ignore symlinks or junction points (which behave like symlinks under Windows). If you supply this flag then rclone will copy symbolic links from the local storage, and store them as text files, with a '.rclonelink' suffix in the remote storage. The text file will contain the target of the symbolic link (see example). This flag applies to all commands. For example, supposing you have a directory structure like this ``` $ tree /tmp/a /tmp/a ├── file1 -> ./file4 └── file2 -> /home/user/file3 ``` Copying the entire directory with '-l' ``` $ rclone copyto -l /tmp/a/file1 remote:/tmp/a/ ``` The remote files are created with a '.rclonelink' suffix ``` $ rclone ls remote:/tmp/a 5 file1.rclonelink 14 file2.rclonelink ``` The remote files will contain the target of the symbolic links ``` $ rclone cat remote:/tmp/a/file1.rclonelink ./file4 $ rclone cat remote:/tmp/a/file2.rclonelink /home/user/file3 ``` Copying them back with '-l' ``` $ rclone copyto -l remote:/tmp/a/ /tmp/b/ $ tree /tmp/b /tmp/b ├── file1 -> ./file4 └── file2 -> /home/user/file3 ``` However, if copied back without '-l' ``` $ rclone copyto remote:/tmp/a/ /tmp/b/ $ tree /tmp/b /tmp/b ├── file1.rclonelink └── file2.rclonelink ```` Note that this flag is incompatible with `-copy-links` / `-L`. ### 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). #### --copy-links Follow symlinks and copy the pointed to item. - Config: copy_links - Env Var: RCLONE_LOCAL_COPY_LINKS - Type: bool - Default: false #### --skip-links 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](https://github.com/ncw/rclone/issues/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
