-# tape_splitsize - (optional) split dump file into pieces of a specified size.
-# This allows dumps to be spread across multiple tapes, and can
-# potentially make more efficient use of tape space. Note that
-# if this value is too large (more than half the size of the
-# average dump being split), substantial tape space can be
-# wasted. If too small, large dumps will be split into
-# innumerable tiny dumpfiles, adding to restoration complexity.
-# A good rule of thumb, usually, is 1/10 of the size of your
-# tape. Default: [disabled]
-# split_diskbuffer - (optional) When dumping a split dump in PORT-WRITE
-# mode (usually meaning "no holding disk"), buffer the split
-# chunks to a file in the directory specified by this option.
-# Default: [none]
-# fallback_splitsize - (optional) When dumping a split dump in PORT-WRITE
-# mode, if no split_diskbuffer is specified (or if we somehow
-# fail to use our split_diskbuffer), we must buffer split
-# chunks in memory. This specifies the maximum size split
-# chunks can be in this scenario, and thus the maximum amount
-# of memory consumed for in-memory splitting. Default: [10m]
