|
|
rclone mount allows Linux and macOS to mount any of Rclone's cloud storage
|
|
systems as a file system with FUSE.
|
|
|
|
This is **EXPERIMENTAL** - use with care.
|
|
|
|
First set up your remote using ` + "`rclone config`" + `. Check it works with ` + "`rclone ls`" + ` etc.
|
|
|
|
Start the mount like this
|
|
|
|
rclone mount remote:path/to/files /path/to/local/mount &
|
|
|
|
Stop the mount with
|
|
|
|
fusermount -u /path/to/local/mount
|
|
|
|
Or with OS X
|
|
|
|
umount -u /path/to/local/mount
|
|
|
|
### Limitations ###
|
|
|
|
This can only read files seqentially, or write files sequentially. It
|
|
can't read and write or seek in files.
|
|
|
|
rclonefs inherits rclone's directory handling. In rclone's world
|
|
directories don't really exist. This means that empty directories
|
|
will have a tendency to disappear once they fall out of the directory
|
|
cache.
|
|
|
|
The bucket based FSes (eg swift, s3, google compute storage, b2) won't
|
|
work from the root - you will need to specify a bucket, or a path
|
|
within the bucket. So ` + "`swift:`" + ` won't work whereas ` + "`swift:bucket`" + ` will
|
|
as will ` + "`swift:bucket/path`" + `.
|
|
|
|
### rclone mount vs rclone sync/copy ##
|
|
|
|
File systems expect things to be 100% reliable, whereas cloud storage
|
|
systems are a long way from 100% reliable. The rclone sync/copy
|
|
commands cope with this with lots of retries. However rclone mount
|
|
can't use retries in the same way without making local copies of the
|
|
uploads. This might happen in the future, but for the moment rclone
|
|
mount won't do that, so will be less reliable than the rclone command.
|
|
|
|
### Bugs ###
|
|
|
|
* All the remotes should work for read, but some may not for write
|
|
* those which need to know the size in advance won't - eg B2
|
|
* maybe should pass in size as -1 to mean work it out
|
|
|
|
### TODO ###
|
|
|
|
* Tests
|
|
* Check hashes on upload/download
|
|
* Preserve timestamps
|
|
* Move directories
