using encrypted drives (not VVP encryption)

[wayneT]

We use a piece of software installed on the machine to encrypt data (not VVP). Will VVP still be able to copy the data and in what state will it be in, the original encrypted state?
Thanks

Do not know, it depends on the encryption software. You could try and see if the destination files are encrypted or not. thanks

I use PGP Disk. VVP backs up the containers, the .pgd files, with no problem. Generally the PGP Disks are unmounted when VVP runs, and I'm not sure if it would have problems if the PGP Disks were mounted.

Note that I do NOT ask VVP to back up the files within the PGP Disk. This would result in unencrypted backups unless the target were also encrypted. But encrypting the target would require leaving the target mounted overnight for VVP to use, or else somehow scheduling it to be mounted, either of which would compromise the security of the encrypted files.

Of course, this means that when I change any file within the PGP Disk, the entire .pgd container file must be backed up. This is one reason I use several separate PGP disks -- when I update a file, at least only the containing .pgd file has to be backed up. This is a basic problem with encrypting many files in one container -- if it's worth encrypting the data, then you don't want a backup program to be able to see the decrypted file.

These are great LENOVO drives for storing encrypted data:

We have one in our office and it works great!

We combine this drive with ViceVersa file-by-file encryption so all backups are double encrypted
