I noticed there is currently no limit on the number of manual backups, which could lead to potential abuse of remote backup server space.
Thank you for bringing this to our attention. Currently, our system does offer the flexibility to limit backups by either size or number when utilizing Remote Backups. For detailed guidance on setting these limits, please refer to our documentation here: Remote Backups Configuration.
Furthermore, we are actively working on expanding this functionality to include backup limits even when Remote Backups is not in use. This feature is expected to be available in the upcoming v1.1.5 release.
