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

Table 3 Source and Target for a File Level Incremental Backup of an HP-UX EVFS Volume

Source/Target Description

Source HP-UX EVFS volume

Target File library device or a device that

supports file system back up in a

directory on which the HP-UX EVFS

volume is mounted.

To perform a file level incremental backup of an HP-UX EVFS volume, complete the following steps:

Step 1 To create a sample encrypted volume with a file system on the source HP-UX EVFS volume,

complete the following tasks:

1. Create a source LVM volume.

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

3. Generate user keys for the HP-UX EVFS volume.

4. Create the EMD area on the source HP-UX EVFS volume.

5. Enable the source HP-UX EVFS volume.

Important:

After encryption and decryption for an EVFS volume is enabled, any entity

reading the data from the HP-UX EVFS volume receives the data in clear

text. You must use normal HP-UX file system permissions and access control

to restrict access to the data.

6. Create a file system on the source HP-UX EVFS volume, and mount the file system.

7. Create a sample directory with sample files in the directory on which the source HP-

UX EVFS volume is mounted, to verify if the data is backed up and restored properly.

Step 2 To create a sample encrypted volume with a file system on the target HP-UX EVFS volume,

complete the following tasks:

1. Create a source LVM volume.

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

3. Generate user keys for the HP-UX EVFS volume.

4. Create the EMD area on the target HP-UX EVFS volume.

5. Enable the target HP-UX EVFS volume.

6. Create a file system on the target HP-UX EVFS volume, and mount the file system.

Step 3 Ensure that the source and target HP-UX EVFS volumes are enabled.

Step 4 Pass the sample directory with the sample files, where the source HP-UX EVFS volume is

mounted, to the Data Protector. Target is the required file device in the target directory on

which the target HP-UX EVFS volume is mounted.

Step 5 Start the backup session.
