An unknown backup-to-disk folder was found at the specified path

Hello.

I have a disaster in my system, and I need to recover a backup.

Because of the disaster I have lost symantec backup too, I have reinstalled it, and when I try to connect to my backup folder, it says:

An unknown backup-to-disk folder was found at the specified path

And ask me to create a new one.

Why am I seeing this message? The backup folder looks good.

If I create a new one.. Will I loose all the backups I have in that folder?

Thanks in advance.
