|
|
-----------------------------------------
|
|
|
|
The `Compress` remote adds compression to another remote. It is best used with remotes containing
|
|
many large compressible files.
|
|
|
|
Please read the [warnings](#warnings) before using this remote.
|
|
|
|
To use this remote, all you need to do is specify another remote and a compression mode to use:
|
|
|
|
```
|
|
Current remotes:
|
|
|
|

|
|
e) Edit existing remote
|
|
$ rclone config
|
|
n) New remote
|
|
d) Delete remote
|
|
r) Rename remote
|
|
c) Copy remote
|
|
s) Set configuration password
|
|
q) Quit config

### Compression Modes
|
|
Currently only gzip compression is supported, it provides a decent balance between speed and strength and is well
|
|
supported by other application. Compression strength can further be configured via an advanced setting where 0 is no
|
|
compression and 9 is strongest compression.
|
|
|
|
#### Filetype
|
|
If you open a remote wrapped by press, you will see that there are many files with an extension corresponding to
|
|
the compression algorithm you chose. These files are standard files that can be opened by various archive programs,
|
|
but they have some hidden metadata that allows them to be used by rclone.
|
|
While you may download and decompress these files at will, do **not** manually delete or rename files. Files without
|
|
correct metadata files will not be recognized by rclone.
|
|
|
|
### File names
|
|
|
|
The compressed files will be named `*.###########.gz` where `*` is the base file and the `#` part is base64 encoded
|
|
size of the uncompressed file. The file names should not be changed by anything other than the rclone compression backend.
|
|
|
|
#### Experimental
|
|
This remote is currently **experimental**. Things may break and data may be lost. Anything you do with this remote is
|
|
at your own risk. Please understand the risks associated with using experimental code and don't use this remote in
|
|
critical applications.

### Standard Options
|
|
|
|
Here are the standard options specific to compress (Compress a remote).
|
|
|
|
#### --compress-remote
|
|
|
|
Remote to compress.
|
|
|
|
- Config: remote
|
|
- Env Var: RCLONE_COMPRESS_REMOTE
|
|
- Type: string
|
|
- Default: ""
|
|
|
|
#### --compress-mode
|
|
|
|
Compression mode.
|
|
|
|
- Config: mode
|
|
- Env Var: RCLONE_COMPRESS_MODE
|
|
- Type: string
|
|
- Default: "gzip"
|
|
- Examples:
|
|
- "gzip"
|
|
- Standard gzip compression with fastest parameters.
|
|
|
|
### Advanced Options
|
|
|
|
Here are the advanced options specific to compress (Compress a remote).
|
|
|
|
#### --compress-level
|
|
|
|
GZIP compression level (-2 to 9).
|
|
|
|
Generally -1 (default, equivalent to 5) is recommended.
|
|
Levels 1 to 9 increase compressiong at the cost of speed.. Going past 6
|
|
generally offers very little return.
|
|
|
|
Level -2 uses Huffmann encoding only. Only use if you now what you
|
|
are doing
|
|
Level 0 turns off compression.
|
|
|
|
- Config: level
|
|
- Env Var: RCLONE_COMPRESS_LEVEL
|
|
- Type: int
|
|
- Default: -1
