Besides "what Lauenz said" (especially about the horribly ooutdated
PostgreSQL version): check IO speed and saturation during backup
and make sure you're not stalling. I've seen this beaviour a few
times, mostly in conjunction with btrfs - using a suitably proven
filesystem usually solved the problem (overloaded hardware can
be a problem, too - but modern systems can take quite a bit more
than in the olden days of spinning rust).
Regards,
Christoph
