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.
