For Perkeep alternatives, identify what you rely on: file preservation, metadata, search, or synchronized access. A generic file store may cover only the first part.
- Import a sample of documents, photos, and metadata.
- Verify checksums after upload and a clean restore.
- Search by tags, dates, and relationships; compare result quality.
- Test deduplication, versioning, access control, and remote synchronization.
- Export the sample and reconstruct its metadata without the original server.
Treat discoverability as part of preservation. Data you can store but cannot later identify is not a successful archive.
