Check database size in previous day
I want to ask how do I get database size in previous day (example: Today is January 31st, and I want to get database size in January 22nd). Note: I do not have regular backups.


That's impossible. You could easily script a daemon (with something like du) that recorded that. Or you could use something an lvm snapshot or XFS to get that information, if you were using a stack like that. But MySQL doesn't just record how big the database was at an arbitrary time.
