You might consider checking out pgbackrest and the incremental backup
and delta restore options that it has. Incremental backups will only
copy files from the PG server that have changed since the last backup,
and the delta restore option will only update the files that are
different between the backup and the files that are in place.
pgbackrest is also able to parallelize these operations.
(this use-case, more-or-less, was part of the original reason pgbackrest
was developed, btw)
Thanks,
