Description
The readsbheader command can be used to read the header information on any
SysBack backup. It can be used to list the general header information, the list of
images (logical volumes and filesystems) included on the backup, and the list of
files and directories included on the backup. This command is useful for reading
the contents of an unknown backup tape when no printed label was affixed.
If the backup media is a tape that contains multiple backups, you can read the
header information from any backup on the tape by using the -i “sequence”
option. The sequence refers to the backup sequence number, “1” being the first
backup on the tape and so on.
Flags
-c “termdev”
If the backup contains multiple tape volumes, the volume prompt is sent to the
display indicated by “termdev” (such as /dev/tty0 or /dev/lft0). If the -h
“hostname” option is specified, this flag specifies the display on the remote
host.
-d
Indicates that a list of logical volumes and filesystems included on the backup
should be displayed also.
-f “device or file”
Tape device, virtual device, or filename containing the backup. If a filename is
specified, the information is read from the file on the disk with the “.TOC”
extension. You do not need to supply this extension.
-h “hostname”
Hostname of backup server to which the remote backup device is attached.
-i “sequence”
Indicates the backup sequence number to read. “1” refers to the first backup on
the tape, and so on. The default is “1.” This option can be specified only when
reading from a tape drive or virtual device.
-l Indicates that a list of files and directories included on the backup should be
displayed. This file list can be very long. The directories are listed first,
followed by the regular files.
