Vultr AND Linode. 1) Upload a custom ISO with ZFS (https://github.com/beren12/zfs-iso/ https://github.com/beren12/zfs-iso/) 2) Create a new VPS without OS and boot to your uploaded ISO. 3) Create a ZFS root pool and bootstrap your Debian or another distribution. 4) Enable all cool features: compression, encryption, etc. 5) rsync your zfs snapshots from Vultr to Linode and vice-versa. This is how I do. You can even use them as templates for newly VPS. And for backups, BackBlaze B2 and WASABI with a zfs-snapshot-upload script.
