Hi Dan, thank you for reporting the issue and sharing your enhancement proposals.
Regarding the failed backup, we are preparing a bug fix that will at least indicate whether the backup was successful or not: UI doesn't show backup failure · Issue #7093 · NethServer/dev · GitHub.
As for the validation and error reporting of S3 backup providers, this remains a challenging area. While we’ve made improvements for some providers, the lack of universal standards leaves certain cases unresolved. Currently, the implementation depends on both Rclone and Restic to access S3 storage. I believe we should modify the Restic configuration to rely solely on Rclone. Using a single driver for all storage types would make the behavior more consistent and easier to validate.
