We have not seen this message, but have occasionally seen a related but far more serious problem: a file that was not backed up because a size allocation was underestimated and the server could not provide enough additional disk space. This usually happens when the client tries to compress files already compressed by other software. We have been able to get rid of most problems with disk space estimates by adding 'exclude.compress' statements for compressed file formats. For example, many of our HP-UX systems now have 'exclude.compress *.gz' in their include/exclude files.
