Air Cleaner User Manual

-b “size”
Specifies the buffer size in K-bytes (1024-bytes). Changing this value either
increases or decreases the amount of data that is written to the output device
at one time. Some devices with small buffers might require you to reduce this
value, while other devices with very large buffers can benefit from increased
performance by increasing this value. If you are unsure, use the default value
(64 Kbytes).
-B “backend”
Specifies any single character representing the command used to create the
data stream.
-c “termdev”
If the backup contains multiple tape volumes, the volume prompt is sent to the
“termdev” device (such as /dev/tty0).
-C
Indicates the backup should be performed with a multi-copy write policy. The
same data is written to all specified devices. If used, multiple device names
must also be provided.
-d “description”
A custom description to be included in the backup header. Up to 60 characters
can be used. This information will be placed in the backup header. If the
description includes spaces, the entire description must be enclosed in double
quotation marks (″).
-e Indicates all devices (if tape) should be rewound upon completion. The default
is to not rewind at end.
-i “file”
Indicates the name of a file or logical volume (with /dev prefix) that contains
the data to be written using sbwrite. If not specified, sbwrite reads the data
from standard input.
-l “level”
Specifies a single character representing the incremental backup level. SysBack
backups use a digit between 0 and 9.
-L “file”
Indicates the file list, included in the file specified by the “file” parameter,
should be included on the backup.
-n “contents”
If supplied, “contents” describes the contents of the backup (such as the
volume group name or directory name). Up to 128 characters can be included.
This information is placed in the backup header. If contents includes spaces,
the entire contents must be enclosed in double quotation marks (″).
-p
Indicates the data being sent to sbwrite is packed (compressed). This is
informational only and does not alter the input data. Specifying the -p flag
with sbwrite causes the “Packed” field in the backup header to show “Y”
when reading the header with the “sbread -H” command.
-P
Indicates the backup should be performed with a parallel write-policy, so all
specified devices should be written to synchronously. If specified, multiple
device names must be supplied.
