Complete Guide: How to Set up Rsync Automatic Sync

Keeping files safe and updated is a must these days. Rsync's great for syncing files, but running it manually? Ugh, time-consuming! That's why automating Rsync is a game-changer. Imagine, your files stay current without you lifting a finger.

This guide's here to help you set up automatic Rsync, so it syncs when files change. Plus, we'll check out other cool tools like Raysync, Resilio, and Massive. Think of it as your easy way to ensure your digital stuff is always backed up and ready.

Question: Is Rsync Automatic Sync Available

Yes! Rsync automatic sync is available and widely used for data backup, synchronization, and disaster recovery.

Rsync is a highly efficient tool because it only transfers the differences between source and destination files instead of resending everything.

However, you must set it up with scheduling tools like cron jobs or trigger-based automation to make it automatic.

How to Set up Rsync Automatic Sync

Setting up Rsync automatic sync ensures that your data is always up to date without manual intervention. Follow these steps for the automatic Rsync Sync setup:

Step 1: Install Rsync

Make sure Rsync is installed on both source and destination machines.

• sudo apt install rsync # For Ubuntu/Debian
• yum install rsync # For CentOS/RHEL

Step 2: Use Cron Jobs for Automation

To schedule an automatic sync, use cron jobs. Open the cron editor:

• crontab -e

Add the following line to sync every day at 2 AM:

• 0 2 * * * rsync -avz /source/directory/ user@remote_host:/destination/directory/

Step 3: Set Up SSH Key Authentication

To avoid password prompts, generate an SSH key:

• ssh-keygen -t rsa
• ssh-copy-id user@remote_host

This allows Rsync to work automatically without manual login.

With these steps, your Rsync automatic sync is now up and running!

How to Trigger Rsync Automatic Sync on File Modification

Instead of running Rsync on a fixed schedule, you can trigger it when files are modified using inotify-tools.

Step 1: Install inotify-tools

• sudo apt install inotify-tools

Step 2: Create a Watch Script

#!/bin/bash

while inotifywait -r -e modify,create,delete /source/directory; do

rsync -avz /source/directory/ user@remote_host:/destination/directory/

done

Save this script as autosync.sh and give it execution permissions:

chmod +x autosync.sh

Step 3: Run the Script in the Background

nohup ./autosync.sh &

This ensures Rsync runs automatically whenever a file changes.

Rsync Top 3 Alternatives for Automatically Syncing Files

• Performance can be affected by network conditions

Pricing Model:

• Small Team: $7 per user per month for 5–15 users
• Medium Team: $11 per user per month for 20–50 users
• Large Team: $14 per user per month for 60–140 users

3. Massive

Massive is designed for high-performance file transfer, particularly for very large datasets and demanding workflows.

For syncing files, if you deal with extremely large files, require consistent high-speed transfers, and need robust automation, Massive is a strong Rsync alternative. It's especially valuable for industries like media and entertainment, scientific research, and data-intensive businesses that need to move massive datasets reliably.

Pros:

• There are no file size limitations, making it ideal for large media files
• Secure, high-speed transfers via cloud infrastructure

Cons:

• Requires an active internet connection for transfers
• Pricing is usage-based, which can be costly for frequent transfers
