The dumpdates file is used to record when a dump was made and which level was used for the dump, and so is really only important if you want to make incremental backups. You can either specify a different, modifiable dumpdates file with the '-D' flag if you want to perform incremental backups, or just make full backups each time by excluding the '-u' flag and a level specification when making the dump. -- "A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools." - Douglas Adams
