Managing remote backups is a critical task for any sysadmin or developer, but the real challenge isn’t just moving the data—it’s managing the storage. Without a proper retention policy, remote servers can quickly become cluttered with outdated archives, leading to storage overages and manual cleanup headaches.
solve the “sync and prune” challenge, we have developed a specialized bash script designed to handle incremental backups via rsync while maintaining a strict retention policy on the remote target.
At Bizmate Solutions Ltd, we prioritise automation and efficiency. To solve the “sync and prune” challenge, we have developed a specialised bash script designed to handle incremental backups via rsync while maintaining a strict retention policy on the remote target.
Standard rsync commands are excellent for mirroring data, but they don’t inherently manage historical versions or clean up old files on a remote destination without risk. Manual pruning is prone to human error and often gets overlooked until a “Disk Full” alert triggers.
Our latest addition to the bash-essentials library automates this entire life-cycle. The script ensures that:
Data is synchronized securely via SSH.
Incremental logic is applied to save bandwidth and time.
Automatic Pruning kicks in after the sync, keeping only a specified number of the most recent backups.
Configurable Retention: Easily set how many backup rotations you want to keep.
Secure Execution: Leverages SSH for encrypted data transfer.
Detailed Logging: Clear output for monitoring and troubleshooting.
Dry-Run Support: Test your pruning logic before committing to deletions.
The script is open-source and available on our GitHub repository. You can integrate it into your CRON jobs to achieve a “set and forget” backup strategy.
