Windows 7: Backup takes 800GB? Manage Windows Backup Disk Space

Backup takes 800GB? Manage Windows Backup Disk Space

How do I control how much disk space my Windows Backup takes up? I have a 1TB external disk for backups and other files. My computer's HDD only has about 250GB capacity. I don't know why my backups file got so bloated. What should I do?

I see that I can delete the older backup file: 22-Oct to 11-Nov. But read the text.
""Deleting previous backups will free up space on your backup location."
So far so good.

Then it continues, "All files backed up during the selected period will be deleted."

I'm pretty sure the text is just badly written. I guess that means the backup-files (on the backup drive) will be deleted. They couldn't mean that the original files (on my data drive) will be deleted. That sure is a scary possibility though. How do you understand this?

Yes, it is perhaps, badly written, but true. All files in the backup period from 22-Oct. to 11-Nov. will be deleted. Not to worry, though, because those same files are backed up in a later backup period from 11-Nov. to ? It is safe to delete older backup periods.

Thank you for the excellent response. I have deleted the older backup.

Another question. On my external drive (for backups) I have files which I cannot open
1. Name-PC-Home
2. WindowsImageBackup

Is Name-PC-Home the Windows Backup (files and system image)?

I think WindowsImageBackup is what I created last month with CloneZilla. I'm not sure. I'd like to delete it if it's now superfluous.

Windowsimagebackup is the HDD image that was created when you ran backup in Windows 7. You should also have a MediaID.bin file as well as a data backup file. The WindowsImageBackup cannot be opened unless the file is mounted. System Image - Extract Files Using Disk Management

So "WindowsImageBackup" is the backup file?
What do you think "Name-PC-Home" could be?

No, "WindowsImageBackup" is your system's image. Basically, it's a carbon copy (snapshot) of your entire C:\ drive. There should be 2 other files on your backup drive, a MediaID.bin file and the other one is your data backup. It could be named anything.
Here's an excellent tutorial on Windows 7 backup and restore.

There are 2 backup processes one uses zip compressed files to backup your files and folders. The other uses vhd format files which are complete images of the partition (everything - OS, programs data...).
When you run "Backup Now" by default it will make the two types of backup.
I go into Change settings and untick the box that says make a system image as well. I make images only when I want to and use the "Create a System Image" on the left in the Backup and restore screen to make images when and on what partition.
