Forget about tedious workarounds—let’s dive into how to simplify the process and keep everything in perfect harmony across devices. Keep reading to discover the secret that’ll save you time, effort, and frustration!
What is Syncing Directories and Why Is It Important?
Syncing directories is the process of ensuring that two or more folders—whether on the same device or different devices—contain the same files and data. It’s essential for keeping data organized, up-to-date, and accessible across multiple locations. If you’re managing files across multiple devices, syncing ensures that any changes made on one device are reflected on all other devices.
For example, imagine working on a project across your laptop and Android phone. Syncing directories between these devices ensures you always have the most current version of your project, regardless of which device you’re using. Syncing is especially useful for backup purposes, as it can automatically update your backup folders to ensure nothing gets lost.
For anyone managing files on Android, syncing directories is a powerful way to keep your data organized without the headache of manually copying files between devices. Let’s dive into how to set up directory syncing on Android using Termux and rsync.
Why Sync Directories with Rsync?
rsync is a versatile command-line tool designed to sync directories and files between different locations. If run as a daemon or periodically via crontab, it is a game changer. It’s highly efficient, supporting local-to-local, local-to-remote, and remote-to-local transfers. rsync offers incremental copying, compression, and the ability to preserve permissions, making it the go-to tool for syncing directories.

Getting Started with Termux and Rsync
To begin syncing directories on Android, you’ll first need to install rsync in Termux, a powerful terminal emulator. Here’s how to get started:
- Install Termux from the Google Play Store or F-Droid.
- Set Up Storage Access by running:bashCopy code
termux-setup-storageThis command creates a directory in Termux that links to your device’s shared storage, typically at/storage/emulated/0/. - Install Rsync by running:
pkg install rsyncNow you’re ready to sync directories on your Android device!
Syncing Directories Locally
Let’s start with syncing directories on your Android device. Suppose you have a directory /storage/emulated/0/SourceDir/ and want to sync it with /storage/emulated/0/DestinationDir/.
Here’s the command you’ll use:
rsync -avh /storage/emulated/0/SourceDir/ /storage/emulated/0/DestinationDir/This command will sync directories by copying all files from SourceDir to DestinationDir while preserving permissions, timestamps, and more.
Syncing Directories with a Remote Server
One of the most powerful features of rsync is its ability to sync directories with a remote server. To do this, use the following command:
rsync -avh /storage/emulated/0/SourceDir/ user@remote.server:/path/to/destination/Replace user and remote.server with your actual username and server address. This command will sync directories between your Android device and the remote server, keeping everything up to date.
Handling Symbolic Links
Sometimes, when you sync directories, you might find that rsync creates symbolic links in the target directory instead of copying the actual files. This happens if the source directory contains symbolic links. To ensure rsync copies the files these links point to, use the -L option:
rsync -avhL /storage/emulated/0/SourceDir/ /storage/emulated/0/DestinationDir/This command will follow the symbolic links and copy the actual files, ensuring your directories are correctly synced.
Sync Directories with Deletion
If you want the destination directory to be an exact mirror of the source directory, including removing files that no longer exist in the source, add the --delete option:
rsync -avhL --delete /storage/emulated/0/SourceDir/ /storage/emulated/0/DestinationDir/This command will sync directories and delete any files in the destination directory that are not present in the source directory.

Security Considerations for Syncing Directories
While syncing directories can streamline your workflow, it’s important to understand the security risks involved. When you transfer data between devices, particularly over the internet, there’s always the possibility of unauthorized access.
Here are some security best practices for safe syncing:
- Encryption: If you’re syncing sensitive files, ensure they’re encrypted before transmission. Tools like
rsyncoffer options to encrypt data withssh, adding a layer of security when syncing remotely. - Secure Connection: Always use a secure connection (e.g., SSH) to prevent man-in-the-middle attacks. Avoid using unencrypted protocols like FTP or HTTP.
- Limit Access: Be cautious when setting permissions for shared directories. Only grant access to necessary users and devices to prevent unauthorized syncing.
By following these simple tips, you can keep your files safe while syncing directories across your Android device and others.

Real-World Use Cases for Syncing Directories
You might be wondering: how does syncing directories on Android really benefit me? Here are some practical use cases:
- Project Collaboration: Sync your working directory across your laptop, Android phone, and cloud services to ensure your project files are always accessible and up-to-date.
- Backup and Recovery: Sync important data like photos, documents, and media files to a secure backup folder on your computer or external storage. That way, if your phone is lost or damaged, you won’t lose everything.
- Multi-Device File Management: Sync directories between Android and other devices (Windows, macOS, Linux) to maintain a seamless workflow. For instance, if you work on a project across multiple devices, syncing keeps everything consistent without hassle.
- On-the-Go File Updates: If you frequently work with large files on your Android device, syncing them to your desktop or cloud can free up space and provide more power for editing.
Syncing directories gives you the freedom to move between devices, platforms, and locations without worrying about losing data or dealing with messy file management.
