how to Name a folder with date and time using batch?

Question

any help would be appreciated

Answer 1

Example - dated directories

In the example below, we first set 3 variables: drive, folder, and backupcmd. The "drive" variable defines the root directory of our backups. The "folder" takes the 2 digit day value from the current date (US date format, taking 2 digits from the date command output, starting at the 7th character), which we will use as a subdirectory. The third variable, "backupcmd" defines our backup command with the appropriate command line switches we want to use.

@echo off
:: variables
set drive=D:\Backup
set folder=%date:~7,2%
set backupcmd=xcopy /s /c /d /e /h /i /r /k /y

echo ### Backing up directory...
%backupcmd% "C:\Program Files\somedirectory" "%drive%\%folder%"

echo Backup Complete!
@pause

This example will backup the "C:\Program Files\somedirectory" folder to "D:\Backup\[dd]" where [dd] is the current day of the month. After a month, we will have 30ish daily copies of the backup... And, because of the xcopy command line switches chosen, following backups will only overwrite files that are newer, speeding up subsequent backups. Alternatively you can add a line to delete the %folder% directory prior to executing the %backupcmd% if you prefer to start clean (and take longer).

Answer 2

What OS is this for?

Whatever you are using, you should be able to get the date as either an arguement to the batch, or from a command.
