Replicate Backups to Offsite on media instead of online ?

I have a Backup Server with around 30TB of Backup Data. I would like to take all Backups offsite once a week.
Unfortunately the daily change of Backup Blocks are so many that we cannot replicate them online. I mean it would be complete overkill to have a 10 GBit/s Line only for replicating Backups.
Any creative ideas how I could take the backups offsite once a week e.g. on a hdd ? Whole datastore does not fit on 1 HDD but only the changes should easily fit.

How did you build your backing storage for the PBS datastore? If it’s a ZFS dataset, you could use ZFS replication to replicate the dataset and it’s changes to a couple sets of drives that can be swapped offsite on a rotation.

Thanks for inspiring me, this sounds like a good start. Yes the datastore is a zfs dataset.
I am thinking about an initial zfs synchronisation on site and then only transferring differential snapshots. They should fit on an external drive for transport.
