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).
