The purpose of this Request for Information (RFI) is to obtain information from the vendor community on the availability, capability, and functionality of on-premise, air-gapped, immutable backup solutions currently offered in the marketplace. At this time, Baltimore County Government (“County”) uses Enterprise backup applications to back up the County’s virtual environment. Snapshots are backed up and saved to local storage at two locations. A third copy of the data is stored in AWS S3 Glacier immutable storage. The total storage requirement for a new on-prem solution is approximately 6PB. The proposed backup solution must be air-gapped, immutable, and on-premise. The solution is required to enable the County to meet RPO/RTO objectives for disaster recovery.
