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.

Kbin no run

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 "$@"

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