Will pgbackrest properly backup and restore the cluster if data/base,

PGDATA=/var/lib/pgsql/9.6/data

$PGDATA/pg_log -> /Database/9.6/pg_log
$PGDATA/pg_xlog -> /Database/9.6/pg_xlog
Yes, this will work. Note that restore does not recreate symlinks by
default so you'll need to specify --link-all to enable symlink creation.
See
https://pgbackrest.org/configuration.html#section-restore/option-link-all
for details.
Using symlinks in this way will make management of your clusters more
difficult, mostly because systems need more provisioning before restores
can be performed. In general I'd recommend against it unless there are
performance considerations.
Now that I'm thinking more about what you wrote... "data" isn't on it's own
partition. data/*base* has it's own partition.
What's the recommended method for putting *base**/* on a partition different
from data/? Or is that not recommended?
