@vladimir Can you try this change https://git.cloudron.io/cloudron/box/-/commit/bedcd6fccf58830b316318699375bc1f582a5d7a ? The file on Cloudron is /home/yellowtent/box/src/storage/s3.js. Essentially change the timeout from 3000 * 1000 to 0. And also change maxRetries to 10. You don't need to restart anything after the change since the code changes are immediately picked up.

I can confirm that, now that the lifecycle settings are correct, backups get physically deleted from B2.

@girish Great! Thanks again for your help debugging this and adding more configuration. Huge help for larger backups like mine.

good points, thanks, gonna switch to cifs then!
