How to get day and date as filename

[denon101]

I am finally trying to get everything sorted with the backups here. What I use currently on each day is

 

C:\WINDOWS\system32\ntbackup.exe backup "@C:\Documents and Settings\admin\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\data\daily.bks" /a /d "Set created %date:-=-%" /v:yes /r:no /hc:off /m differential /j "Daily Diff Backup" /l:s /f "\\san\storage\backup\monday.bkf"

 

Then for each day monday, becomes tuesday etc. But this means I need 4 scheduled tasks for Mon to Thur and a 5th for the Full backup on a Friday. What would be better is on task but it will put something like Monday_15/11/2010.bkf. Anyone have any ideas?

 

Thanks

Can't get the monday, tuesday etc. But have managed to get the date working. It's better than nothing, but if someone does know how to get the day in there aswell that would be great.

if someone does know how to get the day in there as well that would be great.

This will do it...

Just a thought, but with 'date-named' files, I always tend to use the ISO recommendations, most significant part first.

So, today could be something like 2010-11-15--Monday.bkf

Makes it easier to scan directories, script housekeeping, etc.

Very good point. That's actually what I do too since it ensures Windows sorts the files properly. To do this in the batch file I posted above, just replace line 10 with the code below...

 

SET BKFPATH=\\SAN\Storage\Backup\%y%-%m%-%d%_%day%.bkf

 

 

The filename for todays backup would become: 2010-11-15_Monday.bkf instead of just Monday.bkf.
