Controls how Data Protector Express compresses or maintains the compression of files and directories for
both Software and Hardware.
The Software Compression types are either
None
,
Software
,
Operating System
or
Both
.
None:
Instructs Data Protector Express to write all data to the tape in a decompressed format. If the file is
stored on disk in a compressed format, the file will be decompressed before writing. This option is useful
if the device supports hardware data compression and the files are to be restored to a different operating
system.
Software:
Instructs Data Protector Express to write all data to tape in the Data Protector Express
compression format. If the file is stored on disk in a compressed format, the file will be decompressed
before being re-compressed by Data Protector Express. This option is useful if the tape device does not
support hardware data compression and the files are to be restored to a different operating system.
Operating System:
Instructs Data Protector Express to write all data to tape in the same mode it is stored
on disk. If the file is stored on disk in compressed format, Data Protector Express will write the data in the
host operating system’s compressed format. If the file is not compressed on disk, Data Protector Express
will store the file on tape in a non-compressed format. This option is useful if the hardware supports data
compression and the files are to be restored to the same operating system. This option also gives better
performance.
Both:
Instructs Data Protector Express to write all compressed data in its compressed format. Any
uncompressed files will be stored in the Data Protector Express compression format. This option is useful
if the hardware does not support data compression and the files are to be restored to the same operating
system.
The Hardware Compression types are either
None
or
Compressed
. If the backup device supports
hardware compression, be sure to select
Compressed
.
