Redmine

Dear all,

I use the follow command line in Ubuntu to backup MySQL database and upload files:

database:
/usr/bin/mysqldump -u<username> -p<password> redmine | gzip >
/home/redmine_backup/databases/redmine_`date +"20%y.%m.%d_%H.%M"`.gz

upload files:
rsync -a /opt/redmine/redmine/files /home/redmine_backup/files

But, how can I recovery redmine if the system break down?
btw, I know how to setup Redmine step by step in Ubuntu.
But don't know how to recovery the backuped data (redmine_yyyy.mm.dd_hh.mm.gz) into MySQL database.

would someone share the methods to me?

ps. I'm a new guy to use Ubuntu and MySQL, Redmine...

Thank you very much for your attentions!
