Handle edge cases in backup

**Description**
Currently utils lacks proper import support.

**Proposed solution**
Add configurable import with sensible defaults.

**Priority**: Low/Medium

Start by locating the backup and import-related code under utils and read how existing backup handling works. Clarify the supported import sources, configurable options, and sensible defaults before making the change; done means imports work for the identified edge cases with predictable default behavior.
