  • I used to do this all the time! So in terms of speed bcache is the fastest, but it’s not as well supported as lvm cache. IMHO lvm cache is plenty fast enough for most uses.

    Is it going to be as fast as a NVME ssd? Nope. But it should be about as fast as a SATA ssd if not a little slower depending on how it’s getting the data. If you’re willing to take that trade off it’s worth it. Though anything already cached is going to be accessed at NVME speeds.

    So it’s totally worth it if you need bigger storage but can’t afford the SSD. I would go bigger in your HDD though, if you can. Because unless you’re accessing more than the capacity of your SSD frequently; the caching will work extremely well for both reads and writes. So your steam games will feel like they’re on a SSD, most of the time, and everything else you do will “feel” snappy too.
















  • Restic, it has native S3 compatibility and when you combine with something like B2 it makes amazing offsite storage so you can enjoy the tried and true 3-2-1 backup strategy.

    Also fedora magazine did a few posts on setting it up with systemd that makes it SUPER EASY to get going if you need a guide.

    I have an ansible role that configures it on everyone’s laptops so that they have local, NAS, and remote, B2, backup locations.

    Works like a charm for the past 8+ years.
