HP UX Encrypted Volume and Filesystem (EVFS) Performing File Level Incremental Backup of an HP-UXEVFS Volume

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
Step 2	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.
