I have setup the Backup via rsync/SSH with WAL streaming (Scenario 2b as mentioned in barman docs) architecture with a single PostgreSQL and Barman.
I am trying to understand how PITR works with barman recover
command. What would be the expected behavior if one were to specify the current time for --target-time
when issuing a recover command. Would it recover up to whatever WALs barman has last received starting from the backup time up to the current time?
Thanks
For others who might have the same question (given the docs are not clear on this) i found the answer & it is as i expected.
Yes it does recover up to whatever WALs barman has last received starting from the backup time up to the current time.
Please see below console snippet for reference,
