Hello. I’m looking for advice on how best to setup a reliable backup system for one of Discourse forums I administrate. The backup file that gets generated is around 3GB. (This forum was populated by importing 20 years worth of a mailing list emails with images, thus the size.) We use Communiteq (f…

We keep 2 backups and use S3. Our backups include uploads and they are at 8GB now. The RO time during the backups has stayed roughly the same (actually since out last CPU and RAM injection it’s gone down). Keeping much more than 2-7 backups probably isn’t going to help you much. If you get a massiv…

This is great to hear given the size of your backups. I think I will forge on with S3 and try to get it working. Thanks for weighing in!

[imagem] Sander78: Would it be possible for Discourse to create delta backups in the near future? I’d consider it extremely unlikely. Taking a diff of a relational database is far from trivial, and the gains are minimal. If you’re running a large enough site to make app-level “delta backups…

Full DB and delta of uploads should both be doable and much smaller for a site like this. That’s not something available now. Even just full DB and no uploads might be useful for a case like this. And that’s a currently supported backup option. [imagem]

Just skipping uploads is probably sufficient. The images are usually much much larger than the DB.

Would it be possible for Discourse to create delta backups in the near future? That would save a lot of space for larger forums.
