Iris is a simple utility written completely in python which allows to sync folders between local and remote ssh (sftp) server. Iris runs locally but requires a working python installation on each machine where you want files to be watched.

Iris features are:

• Local and Remote ssh (sftp) directories support
• JumpProxy support for ssh
• Changes are sync in realtime using python watchdogs both locally and remotely
• Modification time is preserved during copy, merge by newer strategy is used
• Pattern / Pattern ignore settings
• Progress bars during large transfers

Linux / Mac / Windows support (UNTESTED Windows)

git clone https://github.com/JunkyByte/iris.git
cd iris/
pip install .

On remote host you do not need all dependencies, if you have a working python3 env just install the watchdog package and you should be set

pip install watchdog

Inside your terminal you can start iris by typing

iris --config config_file.yaml

Other options are --debug that does not require any explanation and --dry which allows you to run iris in test mode, no file writing will be actually done (please use this to test your settings without altering your files).

To create a configuration file with ease you can use

iris-init  # The default name will be iris_conf.yaml
iris-init --config my_new_config.yaml  # You can specify the file path

Config files are in yaml format, the following parameters can be specified, the default value of optional is specified below.

origin:  # local or the host for sftp (if not port specified 22 will be used) (e.g. [email protected]:42)
origin_jump: # host to use for jumping the ssh connection (optional) (e.g. [email protected]:42)
dest:  # local or the host for sftp
dest_jump: # host to use for jumping the ssh connection (optional)
mirror:  # Whether to mirror sync (origin <- dest) (optional, default: True)

# optional, default: '*', e.g. '*.yaml *.txt' to select a directory just use the relative path e.g. './git/'
pattern:  # Patterns for file name matching separated by a space

# optional, default: '//', e.g. '*.md5' to select a directory just use the relative path e.g. './git/'
ignore_pattern:  # Patterns for ignore by file name separated by a space

origin_path:  # The `origin` absolute path
dest_path:  # The `dest` absolute path
origin_key: # The key to use for origin ssh (if is remote)
dest_key: # The key to use for dest ssh (if is remote)

Note that if no user is specified on ssh host the local username will be used.

Right now iris requires a config file to be passed. For remote connections iris will try to load from your ssh-agent first. If it fails it will use the key specified in the config file. More work is required in this regard.

Iris uses asyncssh (which I recommend) for sftp file monitoring / writing, aiofile for async local file writing, watchdog for monitoring file changes, rich for pretty printing, pyYAML for configuration files.

Please create an issue if you have any request / problem or want to contribute.

Password authentication sftp has not been tested and may not work.

Hope you find iris useful.

During a bidirectional sync if you delete a file from the dest_path it will be deleted on your origin_path and vice versa. Also files will be merged based on most recent modification, be careful and run in dry mode first. We do not take any responsability for files lost. Iris is a work in progress, be sure to backup your computer before using it, do not run iris as sudo.
