VBS获取指定目录下最新文件拷贝然后以当前日期命名

近期有个需求，想对数据的备份目录中数据再次远程拷贝到计算机上，所以我们就通过vbs脚本将备份目录下的最新文件拷贝到指定目录，然后以当前的系统日期命名，总结为下：

我们在D盘下的data目录下有系统的备份文件，然后以日期命名，我们想通过获取文件的最后一次修改时间进行获取最新文件，然后进行拷贝

然后拷贝到指定目录中，我们也可以拷贝到远程计算机

我们在本地进行测试，在D盘下的databackup中即可

sourcefilespath="D:\data"

desfilepath="D:\dbbackup\"&""&Year(date)&-Month(date)&-Day(date)&" "&Hour(time)&-Minute(time)&"\"
Set dic=CreateObject("Scripting.Dictionary")
Set fso=CreateObject("Scripting.FileSystemObject")
If Not fso.FolderExists(desfilepath) Then
	fso.CreateFolder desfilepath

End If

backFolderPath=GetLastModify(sourcefilespath)
fso.CopyFile backFolderPath,desfilepath&fso.GetFileName(backFolderPath)

我们执行脚本后，发现以日期命名，然后将最新的数据拷贝到了这个文件夹路劲下

如果一个脚本想实现不同目录的数据拷贝的话，我们也可以通过以下方式写，我们有两种，第一种不正规的写法

sourcefilespath="D:\test"
'desfilepath="\\10.12.0.51\Backup\DataBackup"&""&Year(date)&-Month(date)&-Day(date)&"
"&Hour(time)&-Minute(time)&"\"
desfilepath="e:\data1\"&""&Year(date)&-Month(date)&-Day(date)&"
"&Hour(time)&-Minute(time)&"\"
Set dic=CreateObject("Scripting.Dictionary")
Set fso=CreateObject("Scripting.FileSystemObject")
If Not fso.FolderExists(desfilepath) Then
fso.CreateFolder desfilepath
 
End If
 
backFolderPath=GetLastModify(sourcefilespath)
fso.CopyFile
backFolderPath,desfilepath&fso.GetFileName(backFolderPath)
msgbox "Finish"
 
sourcefilespath2="D:\test2"
'desfilepath="\\10.12.0.51\Backup\DataBackup"&""&Year(date)&-Month(date)&-Day(date)&"
"&Hour(time)&-Minute(time)&"\"
desfilepath2="e:\data2\"&""&Year(date)&-Month(date)&-Day(date)&"
"&Hour(time)&-Minute(time)&"\"
Set dic=CreateObject("Scripting.Dictionary")
Set fso=CreateObject("Scripting.FileSystemObject")
If Not fso.FolderExists(desfilepath2) Then
fso.CreateFolder desfilepath2
 
End If
 
backFolderPath=GetLastModify(sourcefilespath2)
fso.CopyFile
backFolderPath,desfilepath2&fso.GetFileName(backFolderPath)
msgbox "Finish"

我们可以看见，如果有多个目录的话，我们把函数以外的数据进行了多条执行，但是这样不科学，我们可以采用arry的方式，所以修改见下：

sourcefilespath = Array("D:\data" , "D:\data2")
desfilepath = Array("D:\dbbackup\"&""&Year(date)&-Month(date)&-Day(date)&" "&Hour(time)&-Minute(time)&"\" , "D:\dbbackup\"&""&Year(date)&-Month(date)&-Day(date)&" "&Hour(time)&-Minute(time)&"\")
Set dic=CreateObject("Scripting.Dictionary")
Set fso=CreateObject("Scripting.FileSystemObject")
For Each destfold In desfilepath
If Not fso.FolderExists(desfilepath) Then
fso.CreateFolder desfilepath
End If
Next
WScript.Quit
For Each srcfile In sourcefilespath
backFolderPath=GetLastModify(srcfile)
For Each destfold In desfilepath
fso.CopyFile backFolderPath,destfold&fso.GetFileName(destfold)
