Re: file system level backup

I am still not understanding. You have a 2008 server at a and one at b.
You copied the Postgres data files from 2008 server a to 2008 server b.
This did not work, so you say you restored the data directory on server
b from an old copy of the data directory at b.

So where did that old copy come from?

installation).

added databases to postgres-a (postgres-b is empty/new). shutdown
postgres-a and b. copied data-a and b to a network shared between
server-a and b. deleted data-b on server-b. copied data-a from network
to server-b.

copy") to server-b. restarted postgres-b. postgres-b still fails.

So is there anything in the Windows system logs?

Does the Task Manager show another Postgres running?
