we are using Patroni for management of our Postgres standby databases.

we take our (wal) backups on the primary side based on intervals and thresholds.
our archived wal's are written to a local wal directory first and moved to tape afterwards.

we got a case where Patroni switched back and forth sides quickly, e.g.:
12:00h: primary - standby
12:05h: standby - primary
12:10h: primary - standby

we realised that we will not have a wal backup of those wal's generated between 12:05h and 12:10h in this scenario.

how can we make sure that the whole wal sequence trail will be backuped? any idea?

Probably best to ask the Patroni folks:
