That thought crossed my mind recently but I was unsure how to store the |
15 |
cache. But since the repo is a monolith, it should suffice to rsync |
16 |
the whole cache directory to the backup drive (or do it as a tar). |
17 |
|
18 |
The only problem is the temporal sequence: |
19 |
1. Host A runs borg and gets a current cache. |
20 |
2. Host B runs borg on the same repo and gets a current cache. |
21 |
2a. Host A now has an outdated cache. |
22 |
|
23 |
Usually, Host B uses Host A via ssh as remote location of the repository. |
24 |
So I could simply run a borg command on Host A to update the cache somehow. |

I won’t use them at the same time. It will always be one direction: |
31 |
Hosts --[borg]--> Main backup drive --[rsync]--> secondary backup drive |
