Postgres DB backup is taking too much time

Hi,

We have a database of 20TB, and it's taking almost 24 hours to complete.
While full restore takes 28 hours. Although we have HA enabled with primary
and multiple replica's.
*So we need a solution/tool to reduce the RTO, incase of disk failure/
Human error for data/tables deletion.*

We are using Barman for backup.
My question is "Are there any tools like ZDLRA appliances for Oracle" to
reduce the RTO to less than 10 hours".

Best Regards,
Khattak
