It's really great to see this kind of presentation being arranged and
credit to whomever made that happen!

Would it be possible to video this session?

Due to my current medical condition, recovering from emergency gallbladder
removal surgery, I am unable to attend in person and I'm not sure if I can
manage a video stream at that time.

Hi Onno!

> and credit to whomever made that happen!

I'd love to take credit, but Red Hat and the rest of the committee were the
ones that really pushed to make the event happen, so I can't ;)

I believe if we do the presentation through Big Blue Button which I think
is the plan it will be recorded and available for viewing later. Some
coordination with the RH folks will be needed to make that happen, though.

Hi
Is it possible to setup a Backup of linux computer to cloud VM that can be remoted into in the case of failure?

How might this be done? 
What file system setup and which cloud provider might work? 

Thank you

Hi Daniel

You could just push an image straight into AWS EC or Google CE, you would
need to plan and test, some drivers would need effort.

It's probably the wrong way to do it though. It's generally bad practice
and you will experience issues, possibly data loss.

Really you only care about the services and the data they require. So you
need to break those services down and synchronise/replicate the required
data sets and configuration to the cloud.

This is the general direction of virtual infrastructure such as docker /
kubenetes, in some cases you can deploy straight to serverless, such as AWS
lambdas or similar services.

Databases are easily copied or synced, in many cases with HA if you need it
replicated faster.

There's not really any perfect method to do this - it depends on your exact
services, and actual requirements. Very much a "how long is your bit of
string", and how much time have you got to maintain that bit of string.

Hi Daniel,

I got nothing for the kernel, Linux, but I got two recommendations for GNU+Linux (will work on systemd+Linux as well).


For your requested setup, I'm guessing that you're referring to live complete system cloning.

It's possible to do, by shutting your computer down and then using qemu-img to create a VM bootable copy of / .

You then will be able to load that VM image up into a VM provider and have an identical system in the VM.

With a bit of configuration, you could then periodically make the VM sync with your main computer via a periodic crontab that does something similar to:
https://wiki.archlinux.org/title/Rsync#Full_system_backup

Note that there will be issues, as software don't like files being externally changed, plus any issues on the main system will soon propagate to the VM.

One thing that could be a blocker is different CPU flags on your computer and the VM - software compiled to work across all AMD64 CPU's will usually work,
but you'll run into issues if you use software compiled from source with nice flags like -march=native.


As for the VM provider and filesystem, any that accepts qemu images (like qcow2) will do and go for ext4 (as it's well supported and other filesystems don't
provide a worthwhile benefit).



Still, such setup doesn't make much sense, as you'll run into very confusing issues and keeping the VM working will be very time consuming.

A much better idea would be to run 2 completely separate systems in parallel, with data files synced with rsync, but no syncing of the software.

Kind Regards, Gentoo-libre

I run 2 servers here, a primary and backup.

Both are vaguely similar in hardware config, but I use a kernel on the primary that can cope with both.
I use a periodic rsync on all the filesystems. I have a script on the backup that does a couple of things.
- It creates a tgz of specific config files, such as /etc/network/interfaces /etc/fstab /etc/mdadm/mdadm.conf.. and so on.
- It then makes all those files immutable
- Rsync all filesystems
- Remove the immutable bits

Job done. 

The only exception is at time of a major OS upgrade where underlying library or binaries change significantly. At that time, I force a restart after the rsync.
The only other time I restart is if a config change may have impacted the boot process, or the backup needs to go live.

It's all automated, so the backup is never more than a couple of hours behind the prod server.

As long as all the mount points line up and the network interfaces are named appropriately everything "just works" (tm).

Did it take a _long_ time to get right? Absolutely. I've only had to use it in anger once, when I had a RAM failure on the primary.

Biggest benefit?  It gets used *often* to test upgrades or new software before rolling out, because I can do major system upgrades, script, test and then just run the sync script to wipe them back to scratch. Last major OS update I did on the primary was probably tested 30 times on the secondary over several months until I had a script that would run it flawlessly, patch the config files and bring everything back up without operator interaction.
