How to backup/restore(export/import) the Oracle Linux VM snapshot on vSphere 5.5

Greeting,
I have VM and VCenter backup to tape daily. But when I restored the the VM by ArcServe backup, it deleted all the snapshots of that VM and the ASM instance wouldn't start. I am wondering if there is anyway to export the snapshots of VM and import back later on vSphere 5.5

Thanks in advance.

Snapshots are not backups, they are child disks of the parent, which contain the changes, that have occured since the snapshot was activated.

Operating Virtual Disk = Parent VMDK + Child (snapshot) VMDK

sometimes, if you have the snapshot, it is possible to "join" a parent and child together, but the results, can end up with a successful working disk, or it will be corrupted.

and this is completely un-supported.
