  • I’m pretty sure it’s possible to use timeshift to create backups on another drive using rsync (instead of btrfs). They are incremental, and deduplicated, as well.

    But the other commenters are correct, timeshift is not a backup tool, it’s more for snapshots to undo system changes you may not want. In addition to that, it doesn’t do user files by default — because again, it’s not a backup tool.

    btrfs send/receive technically does what you want, using btrfs to do backups to another drive, but I don’t think any GUI app supports it. Plus, you would have to create snapshots for btrfs from the command line.

    Your best bet are apps explicitly designed for this usecase, like someone mentioned pika, or borg or restic are good choices. They don’t do BTRFS, but they do incremental, deduplicated updates in a user friendly way.






  • Should be awful for gaming. It’s possible to run x86 things with emulation, sure, but performance (especially single-thread)

    Most modern software (games excluded), is dynamically compiled. This means that it’s not all one “bundle” that runs, but rather a binary that calls reusable pieces of code, “libraries” from the binary itself. Wine is dynamically compiled.

    What makes modern x86 to arm translators special, is that the x86 binary, like an x86 version of wine, can call upon the arm versions of the libraries it uses ­— like graphic drivers. It’s because of this that the people on r/emulationonandroid managed to play GTA 5 with 30 fps via the computer version. There definitely is overhead, but it’s not that much, and a beefy machine like this could absolutely handle it.

    The Facebook/Meta table had a booth where they had an ARM macbook that was running steam and they were installing games on it.


  • ut I honestly doubt ARM can with the overhead of emulation

  • I despise the way Canonical pretends discourse forum posts by their team members* are documentation.

    I’ve noticed they have been a bit better lately, and have migrated much of the posts to their documentation, but it seems they are doing it again.

    As this is developed, we will update this post to link to the new documentation and feature release notes.

    Pro tip: You could have just made the documentation directly, with the content of this post. Or maybe a blog post. But please stop with the forum posts. They are very confusing for people not used to these… unique locations.

    *Not that people are easily able to find this out when they don’t give any indication that the forum post is something other than just another post by a rando. Actually, I’m just guessing here, based on the quoted reply, for all I know this could be a post by someone unrelated to Canonical. The account is 3 months, and the post itself is identical to a regular forum post from a regular forum member…
