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

Target HP-UX EVFS volume open for raw

access

To restore the backed up data on a tape device (originally created from an HP-UX EVFS volume) to an

HP-UX EVFS volume by using the HP OpenView Storage Data Protector, complete the following steps:

Note:

You must restore the backed up keys of an HP-UX EVFS volume when you

restore the backed up data on the HP-UX EVFS volumes. For more

information on how to restore the backed up keys of HP-UX EVFS volumes,

see Recovering Keys of an HP-UX EVFS Volume

Step 1 Open raw access to the target HP-UX EVFS volume by entering the evfsvol raw

command.

Step 2 Restore the data from the tape device to the target HP-UX EVFS volume by using HP

OpenView Storage Data Protector.

Step 3 Close the raw access to the HP-UX EVFS volume by entering the evfsvol close command

Step 4 Enable the HP-UX EVFS volume, and remount the file system on the HP-UX EVFS volume.

Note:

You need to perform this step only if you want to remount the file system.

For more information on using HP OpenView Storage Data Protector to recover the data backed up

on a tape device by a full volume backup, see Test Scenario 1B. This scenario illustrates the recovery

of data (created by a full volume backup of encrypted data) from a tape device, /dev/rmt/0m, to

an HP-UX EVFS volume, /dev/evfs/vg01/ldp_raw volume, which is open for raw access.

Note:

You can also specify the pre-exec and post-exec commands to restore the

backed up data on a tape device. Specifying the pre-exec commands

includes opening raw access to the target HP-UX EVFS volume. Specifying

the post-exec commands includes closing the raw access to the target HP-

UX EVFS volume.

Performing File Level Incremental Backup of an HP-UX EVFS

Volume

This section describes how to perform a file level incremental backup of an HP-UX EVFS volume using

HP OpenView Storage Data Protector.

You must create either a file library device, or a device that supports file system backup in the

directory mounted on the target HP-UX EVFS volume. This is required because you cannot back up the

data on an HP-UX EVFS volume directly to another HP-UX EVFS volume by using HP OpenView

Storage Data Protector.

Table 3 lists the source and the target for the file level incremental backup of an HP-UX EVFS volume.
