Backing Up and Restoring Data on HP-UX EVFS Volumes Using HP OpenView Storage Data Protector 6.0

Restoring the Backed Up Keys of an HP-UX EVFS Volume

This section describes how to restore the backed up keys of an HP-UX EVFS volume by using HP

OpenView Storage Data Protector.

The backed up keys that are restored include public keys, private keys, and passphrase files in the

default key storage directory (/etc/evfs/pkey). HP recommends that you restore the backed up

keys after you restore the backed up data on an HP-UX EVFS volume.

Note:

Restore the passphrase files only if you are restoring the data back to the

system from which the data was backed up. If you are restoring the data to

a different system, you must create new passphrase files.

Table 6 lists the source and the target for the recovery of the backed up keys of an HP-UX EVFS

volume.

Table 6 Source and Target for the Recovery of Backed Up Keys of an HP-UX EVFS Volume

Source/Target Description

Source Tape device or a file library device

Target Key directory structure on the client

system (where HP-UX EVFS is

configured)

To restore the backed up keys of an HP-UX EVFS volume by using HP OpenView Storage Data

Protector, complete the following steps:

Step 1 To create a sample HP-UX EVFS volume, complete the following tasks (This step is not

necessary if the HP-UX EVFS volume already exists):

1. Create a source LVM volume for the HP-UX EVFS volume.

2. Create HP-UX EVFS volume device files by mapping the LVM volume to EVFS.

Step 2 Restore the keys from the backup medium to the required directory on the client system

by using HP OpenView Storage Data Protector. For more information on using HP OpenView

Storage Data Protector, see the HP Data Protector Software website at:

You can also restore the backed up data to the target client system after restoring the keys.

For more information, see Restoring the Backed Up Encrypted Data Created from an HP-UX

EVFS Volume on a Tape Device, or Restoring the File Level Incremental Backup Data to an HP-

UX EVFS Volume). However, the keys must not be generated in the target client system. The

restored keys must be used (instead of the generated keys) to enable the HP-UX EVFS

volumes.

Note:

Restore the passphrase files only if you are restoring the data back to the

system from which the data was backed up. If you are restoring the data to

a different system, you must create new passphrase files.
