Perform a mysql dump for all databases on a server
url: Connection url
dest: Destination filename
--gzip: Compress output with gzip
--bzip2: Compress output with bzip2
--compress: Compress all information sent between the client and the server if both support compression.
--force: Continue even if an SQL error occurs during a table dump
--disable-keys: This makes loading the dump file faster because the indexes are created after all rows are inserted.
--quick: This option is useful for dumping large tables. It forces mysqldump to retrieve rows for a table from the server a row at a time rather than retrieving the entire row set and buffering it in memory before writing it out.
--add-locks: This results in faster inserts when the dump file is reloaded.
--lock-tables: For each dumped database, lock all tables to be dumped before dumping them. The tables are locked with READ LOCAL to permit concurrent inserts in the case of MyISAM tables
--lock-all-tables: Lock all tables across all databases. This is achieved by acquiring a global read lock for the duration of the whole dump.
--single-transaction: Dumps the consistent state of the database at the time when START TRANSACTION was issued without blocking any applications.
--ignore-tables: Comma seperated list of tablenames to exclude from the dump
--overwrite: Overwrite destination file in case it already exists
