-e Forwards the tape to the end of the last Sysback backup. Used when stacking
multiple backup images on a 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 you
specify a directory, you must also specify an ID using the -I flag.
-g “filename”
Indicates the name of an 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.
-i Indicates to dynamically create a backup file ID when writing backups to disk
image file. This flag supersedes the -I“ID” flag.
-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.
-l “level”
Specifies the backup level (default is 0, or all files). Valid values are 0-9. Only
files created or changed since the last (level - 1) backup was performed.
-M
Retains physical partition mapping, by default, when the logical volume is
recreated from this backup. Unless the logical volume was originally created
using a physical partition map, it is generally recommended that it 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 will be used before recreating the
logical volume.
-n
Indicates that the tape should not be rewound at the beginning of the backup.
This enables the backup to be appended to the previous backup performed.
The tape is not automatically rewound at the end of the backup. The -n option
is always ignored when backing up to a non-tape device.
-O
Overwrites the previous file, if a filename was specified as the output device,
and the filename already exists.
-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 backing up to a disk image file. “u”
indicates only the specified user can read the file. “a” indicates that any user
can read the file.
