You did not mention where the target of the borg backup is, but you want an external service. I believe there is a service that works wells with borg backup, but have not used it.
I did write that the borg backups would be stored on an external drive, sorry that this point wasnt clearer.
I basicly for the start have one big usb 20tb hdd drive (it was discounted and costed only little more than the 12 tb same brand one) to store my backups and i plan to get more drives when i can afford them. The idea with an additional machine i had as well, but thats maybe something further down the road.
the question is that for the start, if a borgbackup of the zfs pool on an external drive with all those services would work. I am a bit worried about their databases yucking up or something.
Yes, but zfs snapshots are not an off-site backup which is more what i am looking for. Besides this, zfs snapshots are of course something i want to implement
