Your mysql database needs to be on persistent storage.

You can add it to backup also, if size is reasanable.

I've been trying to figure out how to do this myself. Can you give more detailed help? I know where to move it to, but when the VM reboots /usr/local/var/mysql gets recreated and mysql thinks that's where the database is.
/usr/local/etc/my.cnf is on the backup and has the database set to /mnt/hda1/database/mysql - but mysql ignores this on reboot.

IIRC the mysql extension still overwrites files on installation, which will happen after restore of backup... would be good to have an updated version, which checks for files and doesn't copy them over, if there are already some in place.

until that is the case you can store and dump your database in a separate archive like backup.tar.gz, put it on /mnt/hda1/ and restore it from /opt/bootsync.sh like

mysqladmin shutdown
tar xzf backup.tar.gz -C /
mysqld_multi start 1

Better yet, modify the my.cnf file, and define the data path to be on persistent storage.

Well, it is rather old. I will update in a week hopefully.
