Comma- or space-separated list of file/directory names to exclude from backup. These
apply across the entire backup.
For example, setting this field to war,plugins
will
allow you to avoid backing up "binaries" that you don't want to back up. But, this will
also exclude any file/directory named "war" or "plugins" anywhere in Hudson's home directory.
If no value is specified, the whole content of the Hudson home directory will be taken
into account.
