Encrypted Backup (Tru64 Unix)

[Roro_2]

Hello,

We have a customer still working on an ES40 Alpha server running Tru64 Unix 5.1.
He is using fdump command to make backup using 40/80GB Super DLT scsi drive.
The customer is asking for an encrypted backup.
Could someone help me to propose a solution.

Thanks and Regards

Roger

Here you have a sample of how to encrypt backups using openssl and the tar command, you can modify it to do it with other backup commands.

Hi Ivan,

Thank you for your concern.
The command "openssl" is not found.
Is there another solution.
Can i use the command "crypt" for the encrypted backup.

Regards

Installing OpenSSL might fix that.

The manpage has clear info!

EXAMPLES
The following examples use KEY as the key to encrypt and decrypt files. The
first example encrypts the file plain.File, naming the resulting encrypted
file crypt.File. The second example decrypts the file crypt.File, naming
the resulting decrypted file decrypt.File. The third example prints the
encrypted file in clear text.

$ crypt KEY < plain.File > crypt.File

$ crypt KEY < crypt.File > decrypt.File

$ crypt KEY < crypt.File | pr

Hello,

It is better to use openssl or crypt commands.
What about performance in case the backup is more than 50GB.
How can i use the vdump command with crypt or openssl command. (all instructions)

Thanks
