Terminology conflict I think :-) The pg_rman docs call backup retention management "backup maintenance" , and retention management is one of the things on the barman todo list.

As for compression, I think barman does log compression not the backups, but it could simply be that the barman docs [1] are out of date where they say :

"Barman’s most wanted features include: backup catalogues, retention policies, remote recovery, archiving and compression of WAL files and of backups."

[1] http://docs.pgbarman.org/

You are right. I confirm, currently it is only WAL compression (documentation is up to date). I hope that we can add one between incremental backups and retention policies in version 1.1. Which are part of the most wanted features still. :)

By then, we'd love to have a Debian package too.

Thank you.

Ah, that makes sense, thanks for the clarification.
