Multipart upload backups to Scaleway S3 aren’t working for me still. Backup Upload to S3 Fails on scaleway (multipart upload)
The problem is, if the upload fails, the backup remains stored locally like when doing normal local backups. Which is good. However the backup limit is ignored, so it will keep filling up the local disk indefinitely with backups until it causes downtime.
This is on 2.6.4 stable.
