It is the year 2020 and replicating APFS containers still sucks. One would expect it would be a simple copy and paste in the Disk Utility app but this is still far from reality.

Last year I wrote how I managed to clone my macOS system under Catalina. The main trick was to create a DMG file with multiple volumes, mount it on target machine and drop to command-line to do asr restore from synthetised disk while avoiding possible pitfalls.

The good news is that Apple devs definitely worked on improving this under Big Sur and added some documentation (see man asr). But I didn't understand it fully on first read. Maybe someone could explain how is this supposed to work?

Recently found some clowny gist was the top result for 'google takeout multiple tgz', where it was using two bash scripts to extract all the tgz files and then merge them together. Don't do that. Use brace expansion, cat the TGZs, and extract:

$ cat takeout-20201023T123551Z-{001..011}.tgz | tar xzivf -

You don't even need to use brace expansion. Globbing will order the files numerically:

$ cat takeout-20201023T123551Z-*.tgz | tar xzivf -

Guide to User-Centric CRUD using Express & Mongoose

Intro

Typically, logged in users interact with an application that results in data being created, updated and deleted.

In almost every case, the application's code will need to ensure that the logged in user can only update/delete data created by them, not the data of other users.

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
