I am proud of course, because a huge amount of time and effort invested in this :)

However, it's really sad that pgBackRest has been closed, because I was led by pgBackRest in some sense when started Databasus

Databasus does support PITR

No, it's logical backup (at least, by the time): PITR are complicated in setting up and recovering.

Yes

To restore database - it should be empty (otherwise conflicts are possible)

Technically, you can try to restore to filled DB. But don't think it makes sense to try

Databasus and WAL-G have completely different architectures. WAL-G is installed on the server with DB. Databasus connects to the database remotely.

WAL-G is about PITR backups, Databasus is about logical ones.

From one side, Databasus usually is slower when database is large.

From another side, it's much easier to use (especially when you have a lot of DBs).

In the future, I am considering implementing incremental backups and following a similar approach as WAL-G or pgBackRest do. But it will be one of options, not mandatory one
