(read\-write) On devices that support it, this property will limit the total amount of data written to a volume; attempts to write beyond this point will cause the device to simulate "out of space\&." Zero means no limit\&. The tapetype parameter \fIlength\fR sets this property\&.

+ (read\-write) If this property is false, limit set by MAX_VOLUME_USAGE property (and thus the tapetype LENGTH parameter) will not be verified while writing to device, allowing the volume to expand without limit\&. If this property is true, then MAX_VOLUME_USAGE willbe enforced, limiting the total size of the volume\&. This property is not available on all devices; see below\&.

Amanda automatically creates a bucket when writing, if the bucket doesn\'t already exist\&. At that time, it specifies where Amazon should store the data based on the S3_BUCKET_LOCATION property\&. If this property is not set, Amazon\'s default value (equivalent to "*") is used\&. The bucket location has both billing and legal concerns, so you are encouraged to consult Amazon\'s documentation for details\&.
.PP
This driver supports the VERBOSE property, but use it carefully \-\- it produces a great deal of output, and may cause spurious failures by filling your debug log partition\&. Its logging is generally only useful for developers chasing down a problem in communications with Amazon\'s servers\&.
.PP
Since Amazon storage is unlimited, the device never encounteres EOM, so LEOM detection is trivially enabled for this device\&.

tapedev "tape:/dev/nst0"
The device name specifies a path to a directory which must exist and contain a "data/" subdirectory\&. Each tape file is stored as a distinct file in this directory, the name of which reflects the Amanda header in the tape file\&. Block boundaries are not maintained: the driver supports reads of arbitrary size, regardless of the blocksize used to write the data\&.
.PP
This device supports LEOM detection\&. LEOM will be indicated when the MAX_VOLUME_USAGE is nearly met, or when the filesystem is nearly out of space\&. The latter circumstance is detected by monitoring the available space on the filesystem, and this monitoring can be disabled with the MONITOR_FREE_SPACE property\&. Note that the device cannot detect other circumstances that may cause a write to fail, such as a filesystem quota\&. LEOM detection can be disabled by setting the LEOM property to false\&.
