Air Cleaner User Manual

This file is used by the installation process to regenerate the same volume
group configuration. This step is ignored if the -g “filename” option was
specified.
4. Places boot image and installation programs on the tape in separate images.
This enables the installation process to be accessed by booting from the tape.
This step is ignored if the backup media is not a tape.
5. The data for each filesystem and logical volume is written to the backup media,
each in a separate backup image.
6. Executes the user-created Post-backup Script. This script can perform any
functions required by the user after the completion of the backup, but prior to
the rewinding and verifying of the backup format. Appendix D, “Creating
Scripts for Customizing the System Backup and Install Process”, on page D-1
provides information on creating this script.
Flags
-b “size”
Specifies the buffer size in K-bytes (1024-bytes). Changing this value either
increases or decreases the amount of data that is written to the output device
at one time. Some devices with small buffers might require you to reduce this
value, while other devices with very large buffers can benefit from increased
performance by increasing this value. If you are unsure, use the default value
(64 Kbytes). The value specified must be a multiple of the tape block size.
-B
Indicates that only boot images are to be created on the tape. This flag is
invalid unless a tape device is specified. When this flag is used, all other
options, with the exception of the device name and platform type, are ignored.
-c “termdev”
If the backup contains multiple tape volumes, the volume prompt is sent to the
“termdev” device (such as /dev/tty0).
-d “description”
A custom description to be included in the backup header. Up to 60 characters
can be used. This information will be placed in the backup header. If the
description includes spaces, the entire description must be enclosed in double
quotation marks (″).
-e Forwards to the end of the last SysBack backup on the tape. Used when
stacking backup images on the same tape.
-f “device, file or directory”
Specifies the output device name, filename, or directory for the backup. The
specified output option can be on the local system or server (if -h option
provided). The device name can be a tape drive or virtual device name. If a
directory is specified, you must also specify an ID using the -I flag.
-g “filename”
Indicates the name of a LVM information file previously created and
customized for this backup. Refer to the mkvginfo and editlvminfo
commands.
-h “hostname”
Name of the remote backup server host to receive the backup data (such as the
data destination host). This is the host that provides the backup device
specified by the -f flag.
