this is what I don't understand. Why would there be a reason to run multiple
backups concurrently? I mean, using pg_start_backup() means I then have to
backup (using whatever method) of the while PGDATA and not just some random
file ${PGDATA}/base/13297/2685. And since I have to backup the whole of PGDATA
anyway, why would I want to do that multiple times, even more so, concurrently?
I read the backup doc but I just can't grasp the idea of why multiple
concurrent backup capabilities should yield any benefit at all.
Cheers,
Paul
