    If paying on a monthly basis, as soon as you pay for 12 consecutive months, you will receive this perpetual fallback license providing you with access to the exact product version for when your 12 consecutive months subscription started. You will receive perpetual fallback licenses for every version you’ve paid 12 consecutive months for.

    So, in your example, you unsubscribe in month 15. This means, you paid 14 months so you get to retain the version from month three (which is 12 full paid months to 14). This means a downgrade to 1.0.x and not to 1.2.x

    I found a blog post outlining exactly that. If you use it locally, it will install and start a service temporarily. That service runs as SYSTEM and invokes your command. To succeed, you need to be a local administrator.

    If you try the same remote, it tries to access \\remote-server-ip\$admin and installs the service with that. To succeed your current account on your local machine must exist on the remote machine and must be an administrator there.

    So in short: It only works, if you’ve already the privilege to do so and the tool itself is not (ab)using a privilege escalation or something like that. Any hacker and virus may do the very same and doesn’t need psexec - it’s just easier for them to use that tool.

    Never thought about that, but since these tools just work, when you copy them to your PC… how does psexec do that? It’d either need you to be an administrator (and then it’s not really a privilege escalation as you could have registered any program into the task scheduler or as a service to run as SYSTEM) or it’d need a delegate service, that should only be available when you use an installer - which again wasn’t was has been done when just copying the tool.

    Windows doesn’t have sudo (not yet, at least) and privileges work a bit different as even as an administrator, you may not have full rights.

    To overcome that obstacle, you’d need to run a shell as an administrator (hold CTRL+Shift, then use the start menu entry or right-click it and select run as administrator).

    Next obstacle: We have a separate drive for each partition, but no root folder.

    If we assume we’re running on a laptop or PC with a single drive and a single partition*, then it’s just

    In cmd.exe:

    del /F /S C:\

    In Powershell:

    Remove-Item -Recurse -Force -Path C:\

    When you want to delete all (mounted) partitions/drives, you need to iterate over them. (Note that’s from the top of my head, didn’t check the script if it works).

    In cmd.exe:

    REM Not gonna do that, I'm no masochist

    In Powershell:

    Get-PSDrive -PSProvider FileSystem | Foreach-Object {
    Remove-Item -Recurse -Force -Path "$($_.Name):\"
}

    Done. Mounting additional partitions before that is left as an exercise for the reader.

    *note that even a standard installation of windows creates 3 partitions. One for the bootloader, one for the recovery system and then the system drive. Only the latter is mounted and will be deleted by this. The other two will still be intact.

    My newest vps runs with Caddy. Works like a charm. The downside was, that I didn’t think of the automatic certificate deployment when I set everything up and it wouldn’t come up a first when I only wanted to connect locally to it, as it tried to get a certificate but the challenge failed because I hadn’t the firewall open yet. But besides that it was very smooth so far.

    Amazon Deep Glacier is a lot cheaper for storage (but expensive for retrieval).

    I use Archive Storage in Oracle Cloud S3 for my dr backups which is their equivalent of AWS deep glacier archive. It’s quite cheap, no restore fees, inbound traffic is free and outbound traffic is only paid, when you’re using more than 10TB per month. (Also first 10 GB of S3 storage is free)

    It’s not the most detailed thing, but I just use a free account on cron-job.org to send a head request every two minutes to a few services that are reachable from the internet (either just their homepage or some ping endpoint in the API) and then used the status page functionality to have a simple second status page on a third party server.

    You can do a bit more on their paid tier, but so far I didn’t need that.

    On the other hand, you could try if a free tier/cheap small vps on one of the many cloud providers is sufficient for an uptime Kuma installation. Just don’t use the same cloud provider as all other of your services run in.

    Also it’s just wrong advice, since you explicitly need --no-preserve-root for it to work… /s

    Jokes aside, please don’t troll anyone with things, that can have severe consequences. Yes, they should have a backup. Yes, they should know how to restore from it. Yes, they should have tested it prior. Yes, you shouldn’t blindly trust people online.

    But even then: Assuming my backup works and I can easily revert the damage. Maybe I need to complete an assignment until tomorrow and just lost 1-2 hours because my PC was busy doing the restore? There’s always a high chance of collateral damage
