IT Notes

What I’ll be describing now is another kind of setup, based on two containers, and it will help you to understand some of the features of Docker.

Docker has been a fundamental part of my setup for more than three years now. Day after day I tried to move as many services as possible to Docker and this was a very good move.

Proxmox Backup Server (PBS) has been released. It’s still in beta but is already perfectly usable. After many years, it’s now possible to perform incremental backups of the VMs and thanks to the qemu dirty bitmaps, backups are also fast.

Many people think that it is enough to ensure that the storage medium is redundant - and you are fine. WRONG!!!!!

I have already dealt with the problem of performing a correct backup. This time I will give you some insights into how I make backups and how I am able to guarantee a certain level of security.

Cephfs is great. It can be used to store and share files and can take advantage of the granularity and performance of Ceph. Big amounts of data can be stored and live snapshots can be taken so remote backups can be easily performed.
