From onboarding to recovery
We develop the backup software and help organisations configure their protection. We discuss which mailboxes, document libraries and cloud flows to include, suitable retention and who should have access.
The first backup and recovery procedure also need attention. We explain the coverage and limitations of each service and discuss how to verify a recovery. For questions about your environment, contact us directly at info@datavault365.com.
