VZRESTORE --> Trying restoring a backup --> A lone zero block at 174

Hello, I have a backup of a CT that want to restore in anoter PC with Proxmox.

I have done the backup in several ways:

- From proxmox gui compressed and uncompressed
- From console using vzdump ......

Nothing strange on .logs

The question is that I move the file to a FTP server and then to my new Proxmox server... in the "dump" folder... and chmod 777

The new Proxmox server is "new" I mean just installed..... you only can see "node" and "storage".....

When I try to restore [vzrestore myvzdump.tar 200] I receive the message like that "Skipping to next header., A lone zero block at 174....."

I don't understand how can be so difficult to restore a backup... many ways... may tries... and no results....

Please help me.

Thanks.
