We'd love to help you with a POC. This is a question that might be best handled with a discussion. Could you contact me directly to set up a call to go over this.
I will try to provide a generic answer as I understand your question. A VoltDB "snapshot" is equivalent to a backup. Snapshots are taken automatically by the command logging feature, and can also be taken automatically on a scheduled basis and manually on demand. They are always taken asynchronously using a background process that allows the workload to continue unimpeded. Because of that, and because they are sequential writes to disk, no special hardware is needed. VoltDB includes the feature and tools to take a snapshot and write it to local disk. From there, the files can be collected and could be archived by third-party software. I'm not sure if this fully addresses your question, so it would help to discuss your particular needs.
