Have you tried syncthing? It works great with keepassxc.

Vaultwarden is pretty easy to self host.

I recommend FSArchiver, it can handle different size partitions

For me: uploading single file using their client ~25MB/s, downloading ~50MB/s (30-60MB/s). In newer versions of their linux client it’s possible to mount filen as network drive or to start webdav/s3 server.

Install Termux and run sshd -D -d -p <port>

You can mount remote with rclone and fine tune caching to your liking: https://rclone.org/commands/rclone_mount/#vfs-file-caching

I use FSArchiver. There’s nice list on Archwiki.

Grab live cd and run it in qemu:

qemu-system-x86_64 -enable-kvm -machine type=pc \
-cpu host -smp 2 \
-m 4096 -device virtio-balloon \
-vga virtio -display sdl,gl=on \
-usb -device usb-tablet \
-boot d -cdrom "$@"

There’s also RCX. But it doesn’t support all possible remotes through gui, however all remote types can be added by importing rclone conf file.

I use rathole tunnel (similar to frp) on VPS and Caddy locally. VPS and my local machine are connected with wireguard VPN. DNS points to VPS, TLS certificates are managed locally by Caddy.

I’m a fan of managing dotfiles with plain git. I think it could be orchestrated a bit to make it more declarative.
