Backup MySQL databases in separate gzipped sql files on Windows

Thx for the script! Can you tell me if there is a way to easily edit the script to allow for multiple databases to be written to separate backup files? In my instance we are running on a Windows Server and we have multiple databases on this machine for development purposes and I am needing to separate out the database backups.

Any help would be greatly appreciated!
Thanks
Marc

Likewise, I have several folders and databases below the data level and need the script to crawl them, backing each one up individually. I can try to hack the script, but this is obviously written more eloquently than any hack I could put together.

Thanks, Ray

Thanks, nice script! But why not use this simple tool MySQLBackupFTP (http://mysqlbackupftp.com/) for making scheduled MySQL database backups.

Thanks

:: get data and time
set hour=%time:~0,2%
if "%hour:~0,1%" == " " set hour=0%hour:~1,1%
set dirName=%date:~0,4%%date:~5,2%%date:~8,2%_%hour%-%time:~3,2%

I have really enjoyed and made good use of this batch file. However it has a couple of issues:

Issue 1: The script won't backup databases that have a dash in the name of the database.
issue 2: The date won't format properly depending on the Windows date format settings.

I have resolved both of these issues in a similar batch file. Feel free to take a look:

It also has an option to just backup a single database instead of all of them.

@michael-milette, loved your script. Saved me a ton of work! Do you have a script for restoring them too?
