Data can be encrypted at the Arcserve Backup server, during the backup process. Using this method, un-encrypted data is transferred from the agent server to the Arcserve Backup server. 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 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 backup window.
If Arcserve Backup detects that the final destination media is not capable of hardware encryption, Arcserve Backup uses software encryption to encrypt the data prior to transferring it to the final destination media.
