BorgBackup: Deduplicating Archiver
There&#x27;s so many backup systems out there these days, but none that are <i>quite</i> perfect.  The closest I&#x27;ve found is `rdedup`[1], which may no longer be maintained.  What I&#x27;d like in a backup solution is:<p>- compressed<p>- deduplicated<p>- encrypted using asymmetric encryption, so that the encrypting machine doesn&#x27;t need to know a password<p>- durable (using par2 or directly supporting repository repair from an independent backup)&#x2F;signed<p>- composed of standard open source tools so that if the backup software goes away, everything can still be retrieved<p>- supports differing upstream data hosting providers<p>- open source<p>There&#x27;s lots of things that fill most of those requirements, but none that tick all the boxes.<p>- rdiff-backup does all of the above <i>except</i> deduplication; it&#x27;s full + incremental which requires a management strategy<p>- restic doesn&#x27;t compress, doesn&#x27;t use asymmetric encryption and doesn&#x27;t use par2 or similar tools for durability<p>- borg doesn&#x27;t use asymmetric encryption and doesn&#x27;t use par2&#x2F;durability stuff; it&#x27;s also pretty slow<p>I know people call borg the &quot;holy grail&quot;, but I think we&#x27;re still a wee way off that emerging, personally -- even though I do really like (and use!) borg.<p>[1]: <a href="https:&#x2F;&#x2F;github.com&#x2F;dpc&#x2F;rdedup" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;dpc&#x2F;rdedup</a>
