So you have: |
| 21 |
Host A ──[hourly]──> Online-Borg A ─┐ |
| 22 |
├──[3/day]──> Offline-Borg |
| 23 |
Host B ──[hourly]──> Online-Borg B ─┘ |
| 24 |
? |

How do you stuff just the latest snapshot of a repo into another repo? |

Apparently you are dealing with some kind of productive, high-availability |
| 35 |
or high-throughput system. I only have my personal stuff, so I don’t mind it |
| 36 |
taking a few minutes. That allows me to watch progress bars and numbers |
| 37 |
going up. :) |

But what is the point of that? Why not simply keep the last x hourly/ |
| 44 |
daily/weekly snapshots? The only thing I can think of is to have a |
| 45 |
small(ish) short-term repo and keep the larger archival repo separate. |
