batch: ntbackup.exe and rotating daily backups

This one is older batch, that will NOT work on Vista or Windows server 2008.

If you need to do rotating daily backups (seven backups), you can use this simple batch code to call ntbackup.exe.

@echo off
for /f "tokens=1-3 delims=. " %%i in ('date /t') do (set day=%%i)
echo Day: %day%
ntbackup backup \\server\share /j "backup %day%" /f "c:\backups\backup.%day%.bak"


This will fill batch variable %day% with current day (two letters) taken from "date /t" command. Then it will call ntbackup to run a full backup of "\\server\share" including all subdirectories (/j) and will store it to "c:\backups\backup.%day%.bak". Variable %day% will be replaced by current day of the week... so this little script will create 7 backups and will rotate them (if you will run it daily using windows scheduler).

This is really simple batch and can be easily modified to do much more.
