  • I moved from VMware Fusion after a hardware failure and migrated to Proxmox. I use VMs to isolate client information and to test and use different OS versions and distros.

    I have a VM that runs Docker and connect to it via SSH for running applications I don’t want to install on my main workstation.

    My main workstation is also a VM.

    I came from bare metal Linux for years and found that I spent too much time recompiling kernels to make it work with my hardware.

    Now that everything is a VM, changing underlying hardware, and even hypervisor is trivial.

    If VMware hadn’t been bought by Broadcom and allowed me to virtualise x86 on Apple Silicon, I’d still be running VMware Fusion. UTM by the way is completely unreliable … I really tried.

    As it is, I’m running Proxmox on AMD.

    in summary, Proxmox allows me to build what I need when I need it virtually and it’s running on a standard Debian host.

    Edit: #$#__# autocorrect (unreadable -> unreliable)




  • What are you using to get it there and back?

    I’m asking because I had been using this for years and only after a catastrophic event, discovered that my “helpful” backup software had turned on versioning which AWS, also helpfully, doesn’t explicitly tell you when you attempt to delete old backup sets, showing no objects but charging you anyway.

    I did recover all my data after a catastrophic event, but it was an expensive experience to put it mildly.

    I think that unless you have some way to enforce accuracy, it’s meaningless and AFAIK automatic detection tools are no better than chance and to my knowledge, getting worse.

    An AI bot operator isn’t going to tag their material as [AI], more likely than not they’d attempt to use [NOT AI].

    I’d also point out that while lemmy doesn’t (yet) support hashtags, any “tagging” would probably benefit from using the existing method using a #tag.

    Ultimately, you need to ask yourself, is undeclared AI that goes undetected by the community a problem, or the new “normal”?

    I’ll note that I’m not a proponent of Assumed Intelligence and think that when the bubble bursts we’re going to be in a world of hurt, but with a little luck the billionaires will have lost their shirts in the process.




  • Have a look at your AWS billing console, since data egress is charged and downloading to verify is considered egress.

    AWS S3 supports data checksums where a checksum is calculated at AWS, which you can compare against a checksum that you calculate locally.

    This is an article that goes into how it works, but I’ve not (yet) tested it, but I’ll be following in your footsteps pretty soon.

    https://medium.com/@maureenosaghae86/check-the-integrity-of-data-in-amazon-s3-with-additional-checksums-3e51fe45f530

    As an aside, make sure that versioning is OFF on your backup bucket unless you specifically require and understand it, because even when you delete objects, they persist as a previous, all but invisible, and charged(!), version.

    My former backup software “helpfully” enabled versioning and I was left with a $600 monthly bill for six months while there was no actual backup being done due to a local hardware failure, until I figured out what was happening. I used that software for years and shudder to think just how much extra it actually cost.

    I will note that while I had a catastrophic hardware failure, I didn’t lose any data.

    Finally, if you’re storing data in Glacier, retrieval is charged at different rates, depending on timelines of access, so it might be that your backup software is using the slow tier to “save” you money.

    Edit: OP advises that they’re not using AWS, instead they’re using OVH. The object storage solutions appear to be mostly compatible, but I was unable to discover if the OVH implementation supports checksums.






  • Not sure how, or if, I’d want to install an Arch package under Debian, but it’s my understanding that the package I’ve raised a bug for under Debian implements, or is supposed to at least, the functionality you’re describing.

    What I haven’t found is a recipe that documents exactly how it’s supposed to work (not to mention, in a Debian way).

    I’d love to discover something that doesn’t start with instructions to remove all pipewire packages and install from source, since that completely defeats the purpose of running Debian Stable as the host.







  • This is the job for the OS.

    You can run most Linux systems with stupid amounts of swap and the only thing you’ll notice is that stuff starts slowing down.

    In my experience, only in extremely rare cases are you smarter than the OS, and in 25+ years of using Linux daily I’ve seen it exactly once, where oomkiller killed running mysqld processes, which would have been fine if the developer had used transactions. Suffice to say, they did not.

    I used a 1 minute cron job to reprioritize the process, problem “solved” … for a system that hadn’t been updated for 12 years but was still live while we documented what it was doing and what was required to upgrade it.
