Re: [Veritas-bu] Encrypted backups of already encrypted data

Thanks, Jeff.
My assumption was the same. I didn't think that NetBackup would bother
to perform any checks to see if a file was already encrypted.
My question was prompted from one of my clients. I don't have any way
of knowing if any of my backup clients are encrypting their disk filesystems
or partitions. I certainly hope my clients haven't purchased a NetBackup
encryption license knowing their systems were already encrypting data.
