I recently had old data from several old hard drives transferred to my new computer by a computer shop. One of the pieces of data is an Acronis .tib file; I chose to use Acronis as a backup tool a few years ago. When I try to "recover" the .tib, which is presumably their term for "extract," I get the following message: "Cannot recover a disk from a backup stored on the same disk."

 

However, I discovered that I'm able to browse through the .tib in Windows Explorer. I tried copying and pasting a file from the .tib to a folder on my computer and it worked.

 

So I suppose there's no severe issue, in that I can copy and paste individual files and folders, but why does the program stop me when I try to extract the whole .tib file?

Just spoke to Acronis about this, and they basically said that's just the way it is, and Acronis backups are special. Nothing against them, though. Chat is not the place to find out the details of why a program works in a certain way.

 

So, Acronis backups literally must be extracted from one drive to another drive; but individual files and folders can be extracted with no restrictions.

No, recover is not extracting. Acronis is a full disk backup application which can also extract individual files.

 

When you recover a TIB backup, you restore a backup to a disk. So you are overwriting the content of the disk with the content of the backup. But if have your TIB file on the same disk to which you want to restore, then your restore would overwrite the TIB backup, and you would lose your data and content of your disk in the middle of your recover operation. And that's why Acronis refuses to do this. It prevented you from shooting yourself in the foot.

 

What you did to extract individual files is probably double-clicking the TIB file. This will "mount" the TIB file as a virtual disk, allowing you to access its content.

Thanks for the clarification. What I wanted to do was mount the file, not recover it.
