Proxmox PVE Host Config Backup Script

This script can be used to backup essential configuration files from the Proxmox Virtual Enivronment (PVE) host.

The script will create backups using tar with specified backup prefix and date and time stamp in the file name. Script will also delete backups that are older then number of days specified.

Create backup script file

To create backup script that will be executed every day we can create backup script in /etc/cron.daily/ folder. We need to make it writeable by root (creator) only, but readable and executable by everyone:

touch /etc/cron.daily/pvehost-backup

Unofficial Bash Strict Mode

Sometimes a programming language has a "strict mode" to restrict unsafe constructs. E.g., Perl has use strict, Javascript has "use strict", and Visual Basic has Option Strict. But what about bash? Well, bash doesn't have a strict mode as such, but it does have an unofficial strict mode:

set -euo pipefail

set -e

Twitch clip datetime userscript

A userscript for displaying the actual date & time (relative to local time) of when a Twitch clip (and video) was created.

FYI: It only works on URLs that start with https://clips.twitch.tv/.
~~This script does not work with URLs that are on the Twitch "channel pages" (https://www.twitch.tv/CHANNEL_NAME_HERE/clip/...).~~
This has been added as of v0.5.0.

"Under the hood" the script uses Date.toLocaleString() to format the date. The format of the date & time may differ from the screenshots below.

We can delete a key from a Python dictionary by the some following approaches.

Using the del keyword; it's almost the same approach like you did though -

     myDict = {'one': 100, 'two': 200, 'three': 300 }
     print(myDict)  # {'one': 100, 'two': 200, 'three': 300}
     if myDict.get('one') : del myDict['one']
     print(myDict)  # {'two': 200, 'three': 300}

GPG - SSH setup

Generating the master key

Here we create the master key. We want only Certify capability: we use the master key only to create the subkeys, Sign - Encrypt - Authenticate capabilities will be assigned to the subkeys.

Run the following command to start the master key generation process. Select the set your own capabilities creation process (type 8)

  ▶ gpg --full-generate-key --expert
