i know the preferred way to do this is via mysqldump but i think that will take forever given the db size. can i just copy the db data files to a new backup directory and tar -czvf that directory?
what are the major risks associated with this quick and dirty approach?
i'm trying to avoid having to get in my car and go down to the hosting center to physically download backups, in order to clear space... :)
thanks in advance for any input!
I'm not sure how good rsync is at diffing binary files
I wouldn't count on this speeding things up.
Between 100 and 400 times faster.

I'm doing a read lock flush, then rsync to a spare server.
Fastest backup system I've ever had for MySQL, and a lot less messy and more reliable than syncronisation which I've also played with (under MySQL 4.* anyway).

Rsync is possible the only option when you're database is really big. Once had to back up an 80+ gig mysql db and rsync was the only option that seamed to work.
Started process, went to sleep, woke up to backup completed.
