Air Cleaner User Manual

-i Indicates to dynamically create a backup file IDD when writing backups to a
disk image file. This flag supersedes the -I“ID” flag and is useful when
scheduling a backup to disk image file.
-I “ID”
This option is used only if a directory is specified as the output device. The ID
is included in the filename created to make it unique from other disk image
file backups. If a backup in the same directory with this ID already exists,
specify the -O flag to overwrite the previous backup.
-k “kernel”
When backing up to tape, indicates the kernel type of the machine that will be
booting from the tape. The default is to create a bootable tape for the current
kernel type.
-M
Retains physical partition mapping, by default, when logical volumes are
recreated from this backup. Unless the logical volumes were originally created
using physical partition maps, it is generally recommended that they not be
recreated using the same partitions, as this would preserve fragmentation that
develops over time as logical volumes and filesystems are expanded. You can
specify whether or not partition mapping is used before the logical volumes
are recreated.
-n
Indicates that the backup is to be placed at the current tape location without
rewinding the tape. Only if the tape is positioned at the start of tape are boot
images placed on the tape. If the tape is not positioned at the start of the tape,
the backup is appended to the prior backup and can later be restored from by
entering a backup sequence number with the sysrestore command.
-N “nettype”
Specifies that device support for the indicated network type should be
included on the tape boot images.
-O
Indicates that, if a filename was specified as the output device, and the
filename already exists, that the new backup will overwrite the previous file.
-p
Indicates that the data should be packed before being written to the media.
This typically reduces size of backup between 25% and 40%. For increased
performance, do not use this option when backing up to a device that provides
hardware data compression.
-r user=[u|a]
Specifies user read permission when writing to a disk image file. “u” indicates
only this user can read the file. “a” indicates any user can read the file.
-r host=[h|a]
Specifies host read permission when writing to a disk image file. “h” indicates
only this host can read the file. “a” indicates any host can read the file.
-T “platform”
When writing to tape, specifies the platform type for which the boot image
will be created. The default is to create boot images for the current platform
type.
-U “host”
Name of the host to be backed up (such as the backup system).
-v Lists the files as they are backed up. This flag cannot be used with the -x flag.
