Air Cleaner User Manual
Unless you are using a virtual device name for the device parameter, specify either
the -S flag (indicating sequential backups), the -P flag (indicating parallel backups)
or -C flag (indicating multi-copy backups). Each of the backup types are described
in Chapter 21, “Virtual Devices”, on page 21-1.
The other options are used by the SysBack backup commands mklvback,
mkjfsback, mkdirback, mkvgback and sysback to define the contents and format
of the data contained in the backup but do not alter the way the data is read using
the sbread command. For example, the -t “type”, -n “description” and -d
“description” flags can be used to supply user and backup-specific information
that will be stored in the header label on the backup.
The type parameter can be one of the following:
s System backup
p Power system backup
v Volume group backup
L Multi-logical volume backup
F Multi-filesystem backup
l Single logical volume backup
f Single filesystem backup
d file/directory backup
o other/unknown. This is the default if none is specified.
The “backend” parameter, specified with the -B flag, can be any single character
that is used by SysBack to keep track of the format of the data in the data stream.
For filesystem data, SysBack uses either “B” for the AIX backup command or “T”
for the AIX tar command.
Data can be compressed using the sbcomp command before sending to the sbwrite
command. If so, you should specify the -p flag to sbwrite, indicating that the data
on the media is compressed, so you will know later to uncompress the data during
a restore.
When sbwrite is executed remotely using the sbclient command, the hostname
and user name of the actual user and host performing the command remotely are
written to the backup header. When executed locally, the local user and hostname,
if any, are included in the header.
To include a file list on the backup, supply the -L flag, followed by the name of the
file containing the file list. This same option can be used to store any type of data.
To read this data from the backup and display the results to stdout, use the -L flag
of the sbread command. Likewise, to store additional information in the table of
contents portion of the backup, use the -T flag with the name of the file containing
the table of contents data. The table of contents can be read from the backup using
the -T flag of the sbread command.
Flags
-a Indicates the device is an auto-loader. User is not prompted to change
volumes, but the reading continues automatically when the next volume is
inserted.
