Kubernetes backup with Velero + MinIO
Here I describe a simple solution for backing up Kubernetes resources. The goal is to have an easy way to back up Kubernetes resources to external storage outside of Kubernetes. To do this, I used my storage server and installed an S3-compatible storage service, MinIO. Velero is installed within the cluster as a backup service, along with a convenient UI called velero-UI, or vui for short. This is intended to be a basis or a starting point for operating Velero.

Automating Efficient VM Backups with Ansible, virtnbdbackup, and Borg
I always wanted a simple and flexible way to back up my KVM virtual machines. In the past, I relied on custom scripts using rsync to copy disk images to a backup location. It worked – but with some annoying downsides: downtime during backup, large backup sizes, and manual effort. At some point, I switched to Proxmox because of its sleek backup system – fast, reliable, and easy to manage. But things changed, and I went back to vanilla KVM setups.
