On: Datomic Free Edition

Transactor local storage is to a directory on the transactor's local disk, and is as safe as you think disks are.

Also: you can backup from one storage system and restore to another. So if you decide you want to upgrade from local disk to DynamoDB, no problem.

Thanks for the clarification. Sounds like one could get away with using the free edition for a pet project website along with some periodic backup of the directory on the transactor machine, but any serious project would wish to upgrade to the DynamoDB version.

It's really not a different story than it is with any traditional filesystem-based database, and as durable.
