8 Best Free Disk Cloning & Backup Tools for Linux (2024)

Disk cloning is the process of copying data from one hard disk to another. While you can perform this task using copy-and-paste methods, it’s important to note that such manual processes may not capture hidden files and folders.

That’s why you need cloning software to do the job, also you may need the cloning process to save a backup image from your files and folders.

Running a Mastodon instance entirely free forever

My single-user Mastodon instance has been ticking away at phocks.eu.org for a while now, over a year at least. All up, I’ve paid zero dollars to keep it running. I’ve had a few people ask me to write up something about it, so here it is.

If you’re comfortable logging into a Linux server via SSH and running commands you shouldn’t have any major troubles setting it up, but it will take a few hours of work. Enjoy!

A handy tip for entering long and/or complicated commands at the Linux command prompt (when using the bash shell) from a Mastodon user

Saw this tip on Mastodon from user Stephan (@durchaus@mastodon.social) and thought it worth passing along:

When you are about to write a long and complicated command in bash, then hit CTRL+x CTRL+e to enter an editor window in which you can write the command with your default editor. The command will be executed immediately after the file is saved and the editor is closed.

(Link to post)

I never knew you could do this. And it was only a year or two ago that I found about about CTRL+r which lets you do a text search for commands in your history (so you don’t need to keep pressing the up arrow). Then again I am not a big command line user, but when I do need to use it, tips like these can be quite helpful IF I can remember them when I need them!

Thanks to Stephan for sharing this tip!

Live Migrating from Raspberry Pi OS bullseye to Debian bookworm

I’ve been getting annoyed with Raspberry Pi OS (Raspbian) for years now. It’s a fork of Debian, but manages to omit some of the most useful things. So I’ve decided to migrate all of my Pis to run pure Debian.
