Backups

Introduction to Resource Management

I’ve seen this go wrong when you’ve got a bunch of background tasks running on your Linux machine, whether it’s a homelab, self-hosting services, or just your everyday desktop. If you don’t manage these tasks, they can consume way too many resources. That’s where nice and ionice come in - they’re essential tools for taming those resource-hungry background tasks.

Understanding nice and ionice

The real trick is understanding how nice and ionice work. nice adjusts the scheduling priority of a process, which is useful when you want to control how much CPU time a process gets. By default, Linux uses a dynamic priority scheduling algorithm, but nice lets you override this and set a manual priority. The nice value ranges from -20 (highest priority) to 19 (lowest priority).

Introduction to Borg Backup

I’ve been on the hunt for a reliable backup solution that can handle my laptop’s limited disk space for ages. When I stumbled upon Borg Backup in 2025, I thought I’d finally found the answer. This deduplicating backup program has been a game-changer, but I soon realized that its default settings weren’t exactly optimized for my laptop’s storage constraints. So, I set out to tame the beast and get Borg Backup to respect my laptop’s limited disk space.

Introduction to Backup Scripts

I’ve been running my own homelab for years, and I’ve learned the hard way that a solid backup strategy is crucial. After trying out various backup tools in 2025, I kept coming back to rsync due to its flexibility and reliability. This year, I’ve been focused on fine-tuning my backup scripts to achieve consistent snapshot rotation. Don’t bother with overly complex backup solutions - rsync is a powerful tool that can get the job done.

Introduction to Borg Backup

I’ve learned the hard way that having a reliable backup system is crucial for any homelab setup. Borg Backup has been my go-to tool for deduplicating backups, and it’s served me well - until I recently encountered a failed repository. This experience taught me some valuable lessons about recovery and prevention.

Understanding Borg Backup Repositories

Before diving into the recovery process, it’s essential to grasp how Borg Backup repositories work. A repository is the central storage location for all your backups, where Borg stores deduplicated data. When you create a repository, Borg initializes it with a unique ID, ensuring data integrity. I’ve seen this go wrong when the repository index gets corrupted, so it’s crucial to understand how it works.
