I have a customer using the SBS Backup Wizrard to backup their server. I am doing some verification of their disaster recovery plan, and noted that on the backup media, their priv1.edb file only takes up 7MB. On Disk, it's about 8GB. The backup method is "normal," and the backups all show "success." Is NTBackup incorrectly reporting the size of the data on tape? Has anyone else noticed a significant difference in file size on Tape vs size on disk of backup files, and .edb files in particular?
