Continuing on a different point while hoping for answer:

Are you familiar with Duplicati’s storage use? It [only backs up changes](https://prev-docs.duplicati.com/en/latest/01-introduction/#features), so use grows slowly.  
This also means that a delete of a version might free up only the changes unique to that one.

[Compare about backup sizes of different versions?](https://forum.duplicati.com/t/compare-about-backup-sizes-of-different-versions/18029) is technical discussions, and led to a tool:

[Duplicati BackupExplorer](https://forum.duplicati.com/t/duplicati-backupexplorer/18950) which I haven’t used, but it might help answer question of data use.

At some point you might just need more disk space, which is one way to also assist compact.

[Compact - Limited / Partial](https://forum.duplicati.com/t/compact-limited-partial/3543) (if done) might be another way to limit the compact space needed. Previously this was sought after more to limit time, but now there’s also space to worry about.
