Hello, We use crunchy postgres operator and for backup database we want use Kasten, we have set policy for backup application for generic backup because we using pv local-storage. We found option use blueprint for backup postgres database with option BEFORE snapshot action. 

In your documentation for Crunchy operators we found that must be enable manual backup. We set this parametr and now we can backup postgres database with using blueprint for crunchy operators.

But we dont know how it works, to NFS storage is store some data after each backup. But is there some option how set some retentional policy for Full,Dif,Inc backup? Because we cannot use full backup for each backup, but if we using incr how will work restore if i will have only incr backup ?

spec:  backups:    pgbackrest:      manual:        repoName: <REPO-NAME>        options:         - --type=incr

Thank you for information
