How to restore a Catalina 10.15 Time Machine Backup on Sierra 10.12

You might be asking… Why the heck are you trying to restore a Catalina backup on to a Mac that is running Sierra? A rational person would just update to either Catalina or Big Sur (released recently at the time of this post) first and then restore. Well until I started writing this post I didn’t realize that was the issue. Here is a small background story on why I’m making this post.

This weekend I had to get my MacBook Pro repaired. Like any responsible computer owner I made sure I had a backup available and ready using the built in time machine backups. The backups get saved to my DS1019+ Synology. Lo and behold my entire MacBook needed to be replaced. No big deal I have a backup right!? So I took the brand new MacBook home plugged it in, and attempted to restore MacBook. I was presented with this….

Anytime I would click Continue nothing would happen. I thought my backup was corrupt. After some searching it turns out Catalina 10.15 introduced a format change for Time Machine Backups on network storage solutions. Previously backups were saved as “ComputerName.sparsebundle” but since my pre-repaired MacBook was running Catalina my backup was named “ComputerName.backupbundle“. This caused some confusion apparently and was making it impossible to restore.

All you need to do is rename your ComputerName.backupbundle file to ComputerName.sparsebundle. Once I did this I rebooted the computer tried again and voilà it worked!

Long story short. When you get a repaired MacBook make sure its updated to the latest MacOS before trying any restores.

Setup and Install Irssi, autodl-irssi, and autodl-rutorrent for ruTorrent in Freenas Jail

Intro

This guide assumes you have rTorrent and ruTorrent configured and running using an account other than root. If you are looking for a guide I found Dan’s guide worked for me.

Installing and Configuring Irssi

For the following steps make sure you are logged in as root.

portsnap fetch
portsnap extract
pkg update
pkg upgrade
pkg install git
cd /usr/ports/irc/irssi
make install clean

Accept all the default configurations. After the process completes confirm Irssi starts. 

irssi
/quit

You should see something like this

Installing and Configuring autodl-irssi

autodl-irssi is a plugin for irssi. The steps bellow will show you how to install and configure.

First use a package manager to install the required Perl modules. If you have not installed cpan run the command below and have the installer do the configuration automatically. This will take some time.

cpan Archive::Zip Net::SSLeay HTML::Entities XML::LibXML Digest::SHA JSON JSON::XS

After this command finishes su into your user account that has access to all rTorrent and ruTorrent files. All commands unless otherwise noted will run as this user.

mkdir -p ~/.irssi/scripts/autorun
cd ~/.irssi/scripts
git clone https://github.com/autodl-community/autodl-irssi.git
mv autodl-irssi/AutodlIrssi/ AutodlIrssi/
cp autodl-irssi/autodl-irssi.pl autodl-irssi.pl
cp autodl-irssi.pl autorun/autodl-irssi.pl
rm -rf autodl-irssi
mkdir -p ~/.autodl
touch ~/.autodl/autodl.cfg

Using your favorite text editor add the following to Autodl.cfg

nano ~/.autodl/autodl.cfg

[options]
gui-server-port = 20546
gui-server-password = 124jklkkj323f2

You can change the port and password if you like. Keep the port between 20000 – 40000. Take note of this information as we will use it one time during the setup. After the configuration you will not need to remember this.

Lets test Irssi to make sure autodl-irssi is loading properly. You should see something like the screenshot below

irssi
/quit

Installing and Configuring autodl-rutorrent Plugin

The plugin requires these PHP dependencies. I will assume you have this installed and configured.

  • json
  • sockets
  • xml
cd /usr/local/www/rutorrent/plugins
git clone https://github.com/autodl-community/autodl-rutorrent.git autodl-irssi
mv autodl-irssi/_conf.php autodl-irssi/conf.php

Now we will edit the conf.php file and change the following values to match the port and password we set above.

$autodlPort = 0;
$autodlPassword = "";

In my case I will change it to

$autodlPort = 20546;
$autodlPassword = "124jklkkj323f2";

Save that file and this completes the setup! Make sure you have irssi start after reboots. There are many ways to do this so if you have questions about that just comment below and I’ll help.
