How Arcserve Backup Encrypts Data During Data Migration

Data can be encrypted at the Arcserve Backup server, during the migration process of a staging job.

Using this method, un-encrypted data is transferred during the backup process of a staging job from the agent server through the Arcserve Backup server to the staging device. The staging device can either be a disk, tape, or virtual tape library (VTL). When the data is ready for the migration process, Arcserve Backup will then detect if the final destination media is capable of hardware encryption or not. If it is hardware encryption capable, then the un-encrypted data is transferred from the staging device to the final destination media where it is then encrypted. This is the preferred and default method because it is faster and does not interfere with the migration window.

If Arcserve Backup detects that the final destination media is not capable of hardware encryption, it will then perform software encryption of the data prior to migration to the final destination media.
