Why it's listed

BorgBackup is listed in backup & object storage because it competes on utility: deduplicating archiver with compression & encryption. It's community-maintained open source: the incentive is the tool itself. Licensed BSD-3; pricing: free. Technically it's lean — it runs comfortably on modest hardware, which is exactly the proof-of-work efficiency we rank for. This entry is provisional — the scores are seeded estimates pending our full manual rubric pass, and the verification date will appear here once complete.
