rBackupper

rBackupper is a console Java application for automated backup of local directories to a remote cloud storage using rclone.

Features

• Backup multiple directories to a remote rclone storage.
• Each backup session is stored in a uniquely named folder.
• Only the latest backup is kept; old backups are automatically deleted.
• Remote trash/garbage is cleaned up after each backup.
• Runs backups in a loop with a user-defined interval.

Requirements

• Java 21+
• rclone (must be installed and a remote configured, see rclone docs)
• Maven (for building)

---

Build

mvn package

---

Run

java -jar target/rBackupper-1.0-SNAPSHOT.jar

---

Usage

On startup, the program will prompt you for:

1. rclone remote name (e.g., gdrive)
2. Number of directories to back up
3. Paths to directories (one per line)
4. Remote backup directory (e.g., backups)
5. Backup interval in milliseconds (e.g., 3600000 for 1 hour)

Example session:

Enter the remote name:
gdrive
Enter the number of paths to back up:
2
Enter each path to back up:
C:\Users\me\Documents
C:\Users\me\Photos
Enter the remote backup directory (e.g., backups):
backups
Enter the backup interval in milliseconds:
3600000

How it works

• The program creates a unique folder for each backup on the remote.
• It copies the specified directories into this folder using rclone copy.
• After a successful backup, it deletes all previous backups except the current one.
• It cleans up the remote trash using rclone cleanup.
• Waits for the specified interval and repeats the process.

---

Notes

• You must have a working rclone remote configured for this to work.
• Only the latest backup is kept; all previous backups are deleted.
• Upload timeout is automatically calculated based on data size (2 minutes per GB).
