The problem is that our Pis have a strange watchdog hardware device and needs to be petted quite often. Because of this, running the watchdog daemon without some

Efficient backup of lxc containers in Proxmox

Lxc containers are fast, small and useful. Proxmox Backup Server is quite slow with them, so here's how to perform a fast and efficient backup using Borg.

Take automatic snapshots of cephfs file systems

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.

BTRFS: performing automatic snapshots and remote backups

One of the interesting features of BTRFS is the dynamic snapshot generation, which grantees the possibility to have a perfect and immediate copy of a specific path.
