Project synchronization with remote server using rsync with exponential backoff. Just place the script at the root of the project and run.

sync.sh

#!/bin/bash

# Sync project with remote server using rsync with exponential backoff.
# Just copy it to the root of the project and make sure rsync is installed before running.
#
# Why I use this script:
#  - sshfs doesn't play well with IntelliJ's file sync (IDE freezes quite often)
#  - pushing silly commits for debugging or running experiments is not a good practice
#
# I built this script to reduce my network traffic and be more efficient in my workflow.
# Personally, I add a configuration for it in IntelliJ with the parameters I want for exponential backoff,
# then I just need to hit a button to send all updates to the server.
#
# Usage example:
#  > sync.sh [user@host:]/path/to/remote/root/ [--dry] [--interval i] [--exp-rate r] [--max-retries m]
