restoring a droplet_A with a backup of a droplet_B

[alexx8bits]

Hi.
I Recently a came across this doubt. For what I understand this is theoretically imposible. A backup of droplet_B can not be used to restore droplet_A. The goal is to have in the end droplet_A=droplet_B. I know there is a more easy way to do this, for example cloning the droplet, but this is my doubt.

The command used to try this was:
dobackup --restore-droplet droplet_A --restore-to "droplet_B--dobackup--2021-09-22 10:59:45"

the result is this error:

2021-09-30 15:54:47,297 [INFO ] Starting Restore Process

2021-09-30 15:55:14,789 [CRITI] NEVER RETURNED, WHILE SENDING <Droplet: 267137674 droplet_A>.restore(), TRYING AGAIN

If I am right and this cant't be achieved, then I think the dobackup tool should handle this error, and says, for example: "there is imposible to restore because the backup if from another droplet" or something more easy to understand like "domain error", jajaja.
