Can I roll forward if I do backups using Mysqldump? Say, I did backups using Mysqldump @ 8:00 AM and my instance crashed @ 2:00 PM. I can restore the tables (both Innodb and MyISAM tables) from my 8:00AM backup, but can I roll forward the data that changed after 8:00 AM or do I lose the data after 8:00 AM. Pls clarify... a link to relevant information would be just fine too...

The dump file will be larger than the MyISAM data file for the original table -- especially if you have many non-text columns (dates, numbers, ENUM columns, etc.). In some cases, when you have large indexes, the index file will be large enough that it and the data file combined will be larger than the dump file, but in some cases it won't be. I wouldn't consider the difference in size, whichever way it goes, to be significant in deciding between backup methods. -- Keith C.
