this should allow us to

define list of datasets that should be automatically snapshotted (for example storage/encrypted on fanny)
define hosts and their datasets that should be backed up
- this would be defined on our offsite machines
- connection will be automatically established through malovpn
- offsite machines will pull backups using backup user

Example configuration on fanny could look like this:

malobeo.backup = {
  enable = true;
  snapshots = [ "storage/encrypted" "zroot/encrypted/var" ];
};

Configuration on offsite machine (assuming it has a pool called backuppool) could look like this:

malobeo.backup = {
  enable = true;
  hosts.fanny = [
    {
      sourceDataset = "storage/encrypted";
      targetDataset = "backuppool/fanny/encrypted"; 
    }
    {
      sourceDataset = "zroot/encrypted/var";
      targetDataset = "backuppool/fanny/var"; 
    }
  ];
};

this should allow us to - define list of datasets that should be automatically snapshotted (for example `storage/encrypted` on fanny) - define hosts and their datasets that should be backed up - this would be defined on our offsite machines - connection will be automatically established through malovpn - offsite machines will pull backups using `backup` user Example configuration on fanny could look like this: ``` nix malobeo.backup = { enable = true; snapshots = [ "storage/encrypted" "zroot/encrypted/var" ]; }; ``` Configuration on offsite machine (assuming it has a pool called backuppool) could look like this: ``` nix malobeo.backup = { enable = true; hosts.fanny = [ { sourceDataset = "storage/encrypted"; targetDataset = "backuppool/fanny/encrypted"; } { sourceDataset = "zroot/encrypted/var"; targetDataset = "backuppool/fanny/var"; } ]; }; ```

This would solve #38 for now. In future we could still think about restic backups for each individual microvm.
