> I hope you had adjusted [blocksize](https://duplicati.readthedocs.io/en/latest/06-advanced-options/#blocksize) on large backups to keep blocks in the backup below a few million blocks. It makes big difference to database performance. Blocksize change does require a fresh start. I first thought this followed on from the paragraph above it, but now I’m thinking it’s the earlier history, especially since first paragraph spoke in future tense. Third paragraph might also be on prior results? I can test the theory if you like, but it looks like it doesn’t even take an err…
