HP UX Encrypted Volume and Filesystem (EVFS) Restoring the Backed Up Data Created from an HP-UXEVFS Volume on a Tape Device

Step 5 Close raw access to the source HP-UX EVFS volume by entering the evfsvol close command to begin the procedure to return the volume to its original state.

Step 6 Enable the HP-UX EVFS volume using the evfsvol enable command, and remount the file system on the HP-UX EVFS volume.

For more information on using HP OpenView Storage Data Protector to perform a full volume encrypted backup, see Test Scenario 1A. This scenario illustrates the full encrypted backup of raw data from a raw volume, /dev/evfs/vg01/ldp_raw volume, to a tape device /dev/rmt/0m.

Note:

You must back up the keys of an HP-UX EVFS volume when you back up the data on HP-UX EVFS volumes. For more information on how to back up keys of HP-UX EVFS volumes, see Backing Up Keys of an EVFS Volume.

Note:

You can also back up and restore data using Data Protector with minimum manual intervention by specifying pre-exec and post-exec commands.

The pre-exec and post-exec commands can be set for a backup specification and, as such, executed on the Cell Manager system, or they can be specified as a backup object option and thus executed on the client system where the respective Disk Agent is running.

Pre-exec and post-exec script commands can be written as executables or shell scripts. These are not supplied by Data Protector and must be written separately by, for example, the backup operator.

Note:

To perform a full volume back up of encrypted data, you must specify the pre-exec and post-exec commands. Pre-exec commands include ensuring that the HP-UX EVFS volume is configured; unmounting the file systems, if any; disabling the HP-UX EVFS volume; and opening raw access to the HP- UX EVFS volume. Post-exec commands include closing raw access to the source HP-UX EVFS volume, and enabling and remounting the file system, if any.

Restoring the Backed Up Data Created from an HP-UX EVFS Volume on a Tape Device

This section describes how to restore the backed up encrypted data (originally created from an HP-UX EVFS volume) on a tape device.

Table 2 lists the source and the target for the recovery of backed up encrypted data that was originally created from an HP-UX EVFS volume.
