We recently moved from Barman to pgBackrest. Our main complaints with barman were that incremental backups utilized hardlinks. Which was great, we could have our 7TB database backed up, and the next day, only 20GB in changes. But, when replicating that data to cloud storage, there is no concept of hardlinks, so now we had to push 14TB to cloud storage. Also, at least last time we looked a while back, file compression was only the WAL files, unless you used the newer barman-cloud-backup tool, which we did not.

Also, pgBackrest lets you do the majority of the backup from a physical standby, which is VERY nice for removing the load off production.

None of these seemed like issues, until we looked at pgBarman, and suddenly realized how nice that would be.

barman seems to cover "Natural disaster" in their docs. Seems good.

I'll take a look. Thanks!
