Years ago, their planet was becoming uninhabitable (think on a planet-wide Chernobyl scale). So they sent their people out into the galaxy, always planning to return when the planet was naturally restored. No matter which planet they travel to, they are not to think of it as home - only their ancestral planet is that.
Before they left, they encoded the sum of the entire planet's knowledge into their DNA (somehow - naturally or artificially) so that they could all have access to their planet's info wherever they went, and preserve and share it with others. In addition, they would add whatever new info they had collected on their travels to their collective knowledge.
Every day, or before a dangerous mission, they would leave a sample of their blood with their knowledge inside behind as a backup in the event of their death, with instructions that it be given to another of their species, or returned to the planet when it's livable again.
Members of this species are essentially a living library of their planet and people, which they can access when necessary.
I imagine a Starfleet crew member of the species, who may have a real name, but is called "Atlas" because he/she bears the weight of a world on his/her shoulders. I also imagine them having a child with a fellow crewmember and naming her "Alexandria" (after the library).
