HP B6960-90078 manual Report Open Locked Files As Windows-Specific Option, Software Compression

Backup

Using Backup Options

	Report Open Locked Files As (Windows-Specific Option)
	This option sets the report level for files that are opened and locked at
	the time Data Protector attempts to back them up. Data Protector
	reports such files as per the regard to the Report Level setting. The
	default value is Warning.
	Software Compression
	Data Protector can compress data on a Disk Agent client before sending
	it to a Media Agent client. This feature is also known as software
	compression. Select Software compression in the Other property page
	of the Object Properties window to enable software compression. In
	this way, you reduce traffic over the network, as well as number of media
	needed and thus improve overall backup performance. Depending on the
	data type, compression ranges from 30% to 70% and is based on the
	Lempel-Ziv 4.3 compression algorithm, which is compatible with the
	standard UNIX compress utility. The progress indication on the monitor
	is not accurate if this option is used.
	The default value is OFF.
NOTE	Most modern backup devices provide built-in hardware compression that
	can be set when you create a device file or SCSI address in the device
	configuration procedure. Do not use software and hardware compression
	at the same time, since double compression decreases performance
	without giving better compression results. See HP OpenView Storage
	Data Protector Installation and Licensing Guide for details on how to
	enable hardware compression.
	HP Ultrium LTO devices do not let you disable automatic hardware
	compression. Keep the default software compression value (OFF) when
	you configure an HP Ultrium LTO drive with Data Protector.
	Uncompress NetWare Compressed Files (Novell Netware Specific)
	By default, Data Protector backs up Novell NetWare compressed files in
	their compressed format. Though this approach speeds up the backup
	process, it makes it impossible to restore the Novell NetWare compressed
	files to any non-NetWare platforms. When this option is selected, Novell
	NetWare compressed files are uncompressed before being backed up.
	Files backed up in this form can be restored to non-NetWare platforms.
