Hi all,

I'm using Windows 7's automatic backup function to backup every Sunday night at 7pm. I'm backing up from my 128GB SSD ultrabook to a 64GB microSD, unfortunately I run out of room after 1 backup. Is there a way to delete my old backup everytime I write a new one at 7pm the following Sunday?

TIA

create a text file called delete.bat (change the .txt to .bat and it becomes a batch file that can be run

paste this in there, changing the directory:

quote:

---

del /f/q/s c:\YOURDIRECTORYHERE\*.*

---

save it on your computer, probably at the root of the C:

Go to Task Scheduler (Control Panel Administrative Tools I think) and create a task to run the batch file weekly before your backup.

I see how to get into the task scheduler. Where do place the task? In the same "windowsbackup" subdirectory?

Did you do a basic task?

When it's looking for the program/script you need to point it to that .bat file you created. I don't think you need to designate a location for the "task" itself, just the batch file so the task knows what to run.

Ok, thank ya

Windows Backup in Win7 automatically overwrites the image it creates with the one it's about to create; deleting anything will likely screw up your backup and render it useless if/when you have to restore it.

The reason why the size is growing is because Windows keeps a catalog of file/system changes and makes a snapshot of these changes. IN your initial backup, the system makes a "base" image. After your initial backup, you're only backing up what changed from the first backup to the second, the second to the third, etc. Deleting any of these will break the backup.

Your best bet is to throw in a secondary drive or buy a sizable external. Also, be careful... flash memory like a microSD is extremely risky - they don't tend to fare well with heavy read/writes like what's done during a system backup.
