Vaultastic makes it easy to bring data into the archive store by simply switching on forwarding within your primary email platform. Features like auto user creation, automatically expanding elastic storage, and unlimited storage on our plans, makes provisioning fully automatic and easy. Similarly, Vaultastic provides multiple easy options to extract data from the archives, allowing export in PST or EML formats or in bulk using the option of an export to an S3 bucket in your AWS account. For large data sizes, you can even opt for the AWS snowball to facilitate physical data transfer.
