- The first setup is not just an install: you must supply destination credentials, choose encryption and retention, preserve the passphrase, and understand how to rebuild from remote volumes if the local database is lost.
- Where Your Data Lives
- Each backup target contains encrypted compressed `.dblock` data volumes, `.dindex` indexes, and one `.dlist` manifest per version; a local database accelerates catalog and restore operations.
- The Catch / Trade-off
- It can automate encrypted backups, but you must choose and pay for storage, protect credentials, monitor jobs, and test restores yourself instead of getting Backblaze's managed service.
