File archive compressed and encrypted with the HyperBac file compression utility; used primarily for compressing database files, including Oracle, MySQL, SQL Server, SharePoint, Sybase, IBM DB/2, and SAP BRBackup database formats; can provide up to a 90% reduction in required storage space. HBE files are similar to standard .HBC files, but are encrypted using AES encryption for file security. HyperBac uses an encryption key file to authenticate the user(s) that can open the file.
