If you log into your PostgreSQL cluster and do 'show data_directory;'
does the result match what you have for pg1-path..?
If you have multiple clusters running on your system (us pg_lsclusters
to check), the issue might be that pgbackrest is connecting to the
default one, which isn't the same as the one that you're trying to do a
backup of. You can change the port for pgbackrest to match if you need
to.
Thanks,
