That seems to have helped a lot. Amanda finally backed up again the same DLE that brought up the issue. Unfortunately, I set the value to 1 Gb, and got two splits, 1.7G and 3.0G. > > > fallback_splitsize > Default: 10M 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.

Sorry, but even after reading your remarks above and experimenting with it, this writeup is still obtuse. For one thing, I had no idea I was splitting in memory.
