What is K3s and MicroK8s?
K3s and MicroK8s are two popular lightweight Kubernetes distributions designed for resource-constrained environments and edge computing. K3s is a highly optimized, certified Kubernetes distribution that can run on a single CPU core and 512 MB of RAM. MicroK8s, on the other hand, is a fast, secure, and lightweight Kubernetes distribution that can be installed on a single node in under 60 seconds.
Main Features of K3s and MicroK8s
Both K3s and MicroK8s offer a range of features that make them ideal for edge computing and resource-constrained environments. Some of the key features include:
- Lightweight and optimized for resource-constrained environments
- Fast and secure
- Support for ARM and x86 architectures
- Integrated container runtime and networking
Why Retention Policies Matter for K3s and MicroK8s Backups
Understanding Retention Policies
Retention policies are a critical component of any backup strategy, and they play a vital role in ensuring that your K3s and MicroK8s backups are properly managed. A retention policy defines how long backups are stored and when they are deleted.
Types of Retention Policies
There are two main types of retention policies:
- Incremental retention policy: This policy involves storing only the changes made since the last backup.
- Synthetic full backup policy: This policy involves creating a full backup from a series of incremental backups.
Incremental and Synthetic Full Backup Tutorial for K3s and MicroK8s
Incremental Backup Tutorial
To create an incremental backup of your K3s or MicroK8s cluster, follow these steps:
- Install the backup tool of your choice (e.g., Velero or Kasten)
- Configure the backup tool to create incremental backups
- Run the backup command to create the first incremental backup
- Subsequent backups will only include changes made since the last backup
Synthetic Full Backup Tutorial
To create a synthetic full backup of your K3s or MicroK8s cluster, follow these steps:
- Install the backup tool of your choice (e.g., Velero or Kasten)
- Configure the backup tool to create synthetic full backups
- Run the backup command to create the first synthetic full backup
- Subsequent backups will be created by combining incremental backups
K3s and MicroK8s Offsite Copies and Immutable Storage
Why Offsite Copies Matter
Offsite copies are an essential component of any backup strategy, as they provide an additional layer of protection against data loss. By storing backups offsite, you can ensure that your data is safe even in the event of a disaster.
Immutable Storage
Immutable storage is a type of storage that cannot be modified or deleted. This type of storage is ideal for backups, as it ensures that your data is safe from tampering or accidental deletion.
