Local Backup of Frozen Image (Local Host)

Volume Manager

As in a file system, the volume manager’s data caching may have to be flushed and

disabled until the frozen image is created. As long as volume manager caching is enabled,

data required for a consistent image may be lingering in volume manager cache rather

than being available on disk when the frozen image is created.

Local Backup of Frozen Image (Local Host)

A frozen image can be backed up to locally attached storage devices, using the Local Host

backup method combined with a frozen image method. A fibre channel network or SAN

is not required.

The following diagram shows a network configuration sufficient for a Local Host backup

of a frozen image. The network configuration is identical to that for normal NetBackup

(no frozen image).

1. Client backup is initiated by master server, which tells the NetBackup client to create the

frozen image data on the disk.

2. Client sends the data to the media server.

3. Media server processes the backup and reads the client data.

4. Media server writes data to local storage.
