两种备份命令基础知识
E:\>cd E:\wamp\bin\mysql\mysql5.0.51b\bin
E:\wamp\bin\mysql\mysql5.0.51b\bin>mysqldump -u root -p dx15>f:/dx15.sql
Enter password: ****
或
E:\wamp\bin\mysql\mysql5.0.51b\bin>mysqldump -u root -p””root”” dx15>F:\dx15.sql
第二种就是””不能少
还原命令
mysql -u root -p dx15< f:\dx15.sql
进入正题
MySQL 安装位置：红色第一行
数据库名称用户名密码：红色第二行前面
数据库备份目的地：D：\db_backup\
——————————————————
新建db_back.vbs，写入下列代码
Dim fName,tNow,CMD
tNow = Now()
fName = Year(tNow) & FormatNumber(Month(tNow)/100,2,false) & FormatNumber(Day(tNow)/100,2,false) & FormatDateTime(tNow,3)
fName = Replace(Replace(fName,”.”,””),”:”,””)
CMD = “”
CMD = CMD & “c:” & vbCrLf
CMD = CMD & “cd C:\Program Files\MySQL\MySQL Server 5.0\bin\” & vbCrLf
CMD = CMD & “mysqldump -u root -p””123456″” test>D:\db_backup\” & fName & “.sql”
Dim FileObject,BatFile,BatPath
Set FileObject = CreateObject(“Scripting.FileSystemObject”)
BatPath = “c:\backup.bat”
Set BatFile = FileObject.CreateTextFile(BatPath, True)
BatFile.WriteLine(CMD)
BatFile.Close
Set BatFile = Nothing
Set FileObject = Nothing
Set WshShell = CreateObject(“Wscript.Shell”)
WshShell.Run BatPath,1,true
Set WshShell = Nothing
然后使用Windows的“计划任务”定时执行该批处理脚本即可。（例如：每天凌晨3点执行db_back.vbs）
