May I trouble you to help me decide on a name for a new service?

I'm torn between ...

1) ParmaSwap

2) RemoteVault

What it is; One ParmaDrive machine does nightly backups to the other ParmaDrive, and vice versa, adding geographical storage redundancy for two people, without needing a cloud service, and no fees. Extra people can be added, but a little more complex.

I like ParmaSwap because of the consistency, and the double entendre, but it's less clear about what it does compared to RemoteVault.

RemoteVault sounds very generic though, and not memorable. Even I forget it momentarily.
