Mail.ru Cloud

Mail.ru Cloud is a cloud storage provided by a Russian internet company Mail.Ru Group. The official desktop client is Disk-O:, available on Windows and Mac OS.

Features highlights

  • Paths may be as deep as required, e.g. remote:directory/subdirectory
  • Files have a last modified time property, directories don't
  • Deleted files are by default moved to the trash
  • Files and directories can be shared via public links
  • Partial uploads or streaming are not supported, file size must be known before upload
  • Maximum file size is limited to 2G for a free account, unlimited for paid accounts
  • Storage keeps hash for all files and performs transparent deduplication, the hash algorithm is a modified SHA1
  • If a particular file is already present in storage, one can quickly submit file hash instead of long file upload (this optimization is supported by rclone)

Configuration

Here is an example of making a mailru configuration.

First create a Mail.ru Cloud account and choose a tariff.

You will need to log in and create an app password for rclone. Rclone will not work with your normal username and password - it will give an error like oauth2: server response missing access_token.

  • Click on your user icon in the top right
  • Go to Security / "Пароль и безопасность"
  • Click password for apps / "Пароли для внешних приложений"
  • Add the password - give it a name - eg "rclone"
  • Copy the password and use this password below - your normal login password won't work.

Now run

rclone config

This will guide you through an interactive setup process:

No remotes found, make a new one?

s) Set configuration password
q) Quit config

in case of generally available files like popular books, video or audio clips

- speedup_enable: true

y) Yes this is OK
e) Edit this remote
d) Delete this remote
y/e/d> y

Configuration of this backend does not require a local web browser. You can use the configured backend as shown below:

See top level directories

rclone lsd remote:

Make a new directory

rclone mkdir remote:directory

List the contents of a directory

rclone ls remote:directory

Sync /home/local/directory to the remote path, deleting any excess files in the path.

rclone sync --interactive /home/local/directory remote:directory

Modification times and hashes

Files support a modification time attribute with up to 1 second precision. Directories do not have a modification time, which is shown as "Jan 1 1970".

File hashes are supported, with a custom Mail.ru algorithm based on SHA1. If file size is less than or equal to the SHA1 block size (20 bytes), its hash is simply its data right-padded with zero bytes. Hashes of a larger file is computed as a SHA1 of the file data bytes concatenated with a decimal representation of the data length.

Emptying Trash

Removing a file or directory actually moves it to the trash, which is not visible to rclone but can be seen in a web browser. The trashed file still occupies part of total quota. If you wish to empty your trash and free some quota, you can use the rclone cleanup remote: command, which will permanently delete all your trashed files. This command does not take any path arguments.

Quota information

To view your current quota you can use the rclone about remote: command which will display your usage limit (quota) and the current usage.

Restricted filename characters

In addition to the default restricted characters set the following characters are also replaced:

Character Value Replacement
" 0x22 ＂
* 0x2A ＊
: 0x3A ：
< 0x3C ＜
> 0x3E ＞
? 0x3F ？
\ 0x5C ＼
| 0x7C ｜

Invalid UTF-8 bytes will also be replaced, as they can't be used in JSON strings.

Standard options

Here are the Standard options specific to mailru (Mail.ru Cloud).

--mailru-client-id

OAuth Client Id.

Leave blank normally.

Properties:

  • Config: client_id
  • Env Var: RCLONE_MAILRU_CLIENT_ID
  • Type: string
  • Required: false

--mailru-client-secret

OAuth Client Secret.

Leave blank normally.

Properties:

  • Config: client_secret
  • Env Var: RCLONE_MAILRU_CLIENT_SECRET
  • Type: string
  • Required: false

--mailru-user

User name (usually email).

Properties:

  • Config: user
  • Env Var: RCLONE_MAILRU_USER
  • Type: string
  • Required: true

--mailru-pass

Password.

This must be an app password - rclone will not work with your normal password. See the Configuration section in the docs for how to make an app password.

NB Input to this must be obscured - see rclone obscure.

Properties:

  • Config: pass
  • Env Var: RCLONE_MAILRU_PASS
  • Type: string
  • Required: true

--mailru-speedup-enable

Skip full upload if there is another file with same data hash.

This feature is called "speedup" or "put by hash". It is especially efficient in case of generally available files like popular books, video or audio clips, because files are searched by hash in all accounts of all mailru users. It is meaningless and ineffective if source file is unique or encrypted. Please note that rclone may need local memory and disk space to calculate content hash in advance and decide whether full upload is required. Also, if rclone does not know file size in advance (e.g. in case of streaming or partial uploads), it will not even try this optimization.

Properties:

  • Config: speedup_enable
  • Env Var: RCLONE_MAILRU_SPEEDUP_ENABLE
  • Type: bool
  • Default: true
  • Examples:
    • "true"
      • Enable
    • "false"
      • Disable

--mailru-speedup-file-patterns

Comma separated list of file name patterns eligible for speedup (put by hash).

Patterns are case insensitive and can contain '*' or '?' meta characters.

Properties:

  • Config: speedup_file_patterns

      • Only common audio/video files will be tried for put by hash.
    • ".zip,.gz,.rar,.pdf"
      • Only common archives or PDF books will be tried for speedup.

This option allows you to disable speedup (put by hash) for large files.

Reason is that preliminary hashing can exhaust your RAM or disk space.

Files larger than the size given below will always be hashed on disk.

Properties:

  • Config: speedup_max_memory
  • Env Var: RCLONE_MAILRU_SPEEDUP_MAX_MEMORY
  • Type: SizeSuffix
  • Default: 32Mi
  • Examples:
    • "0"
      • Preliminary hashing will always be done in a temporary disk location.
    • "32M"
      • Do not dedicate more than 32Mb RAM for preliminary hashing.

Limitations

File size limits depend on your account. A single file size is limited by 2G for a free account and unlimited for paid tariffs. Please refer to the Mail.ru site for the total uploaded size limits.

Note that Mailru is case insensitive so you can't have a file called "Hello.doc" and one called "hello.doc".
