-g vginfo_file
Specify the name of a previously created LVM information file customized
for this backup. See the /usr/sbin/mkvginfo command in Appendix A,
“Commands”, on page A-1for more information on customized LVM
information files. This flag is optional.
The SMIT menu field equivalent to this flag is: no equivalent, command
line only option
-J When logical volumes are recreated from a backup, you may choose to
create them using the exact same physical partitions on the disks on which
they currently reside. This is not possible when installing onto a disk of a
different size or physical location on the system. Specifying this option will
preserve the current mapping of the logical volume, but will also preserve
any fragmentation that currently exists. Preserving the partition mapping is
generally not useful unless the logical volumes were originally created
using partition maps. This flag is optional.
The SMIT menu field equivalent to this flag is: Preserve physical
partition mapping?.
-k buffer_size
The buffer size indicates the amount of data that is written to the output
device in a single output operation. Using a buffer size that best optimizes
a particular device can have significant performance advantages.
Note: The larger the buffer size, the more memory will be used by the
system during the backup.
The SMIT menu field equivalent to this flag is: Buffer size (in Kbytes).
-p Specifying this option will cause the data to be compressed by this system
prior to writing to the backup device. You should not compress data if the
device you are writing to has built-in compression capability. However, if
you are writing the backup to a remote host and wish to send less data
over the network, this option may be useful. However, verify that the
output device does not also have compression set. Compressing data will
use considerable CPU processing on this system, but will result in less data
written to the backup device (in most cases) and usually better backup
performance. This flag is optional.
The SMIT menu field equivalent to this flag is: Compress data before
writing to media?.
-P se this option to crate a SysBack Power Backup, a backup in which all file
system data is backed up as raw logical volumes. In many cases, this will
provide better performance during the backup and during installation from
this backup. However, there are some limitations on related to customizing
the installation. It is not possible to restore select files or directories from
this type of backup. This flag is optional.
Note: Logical volumes are backed up in their entirety, even if the file
systems are only partially full. Therefore, this could decrease the
backup and restore performance.
The SMIT menu field equivalent to this flag is: Create a Power Backup?.
-v Use this flag to display a list of files as they are being backed up. This flag
is optional.
