Desaster Recovery from failover using SLONY-I

Hi,

After a node is dropped due to failover, it takes days to recover the
database, because it is build up from scratch.

We would prefer another approach:
Make an Online Backup of the Provider database.
The provider database continues writing new data and the Slony-Logs.
The Backup is restored to the failed system.
The slony cluster is dropped from the restored system
and the system is defined as Slony-subscriber.
How can we setup this system to recover from the status of the backup time?

Thank you for any hint.
