You are welcome.  Restoring a VM can be done via the ASM/VE GUI, or bring a snapshot of the VMFS volume online in the EQL GUI.  Scan the SCSI adapter on the ESX host and do "Add Storage".   You will see the snapshot of the volume as another Datastore. It will start with snap-xxxxxxxx- .   You can browse that Datastore, select the VM, find the VMDK you want to restore, use copy-n-paste to copy it over to the original VM.   Or if you want to just restore a file,  add the VMDK from the snapshot to a VM as an additional disk.  Then inside the Guest you can copy an file(s) to a share to restore them.    Overall I find doing that is quicker than using the ASM/VE GUI but just has more steps.  Also you can't do file restore via the ASM/VE GUI.  Re: 2.  Correct.  Only the snapshot reserve you allocated to the EQL volume is used to store the snapshots.  No space on the VMFS volume itself is used. 
Bonjour; je suis débutant avec la virtualisation, et j'a commencé à travailler sur les "smart copy"; si j'ai  bien compris, l'une des importantes différence entre snapshot et smart copy, est que la dernière n'est pas stockée sur le même répertoire que  celui de la VM, au contraire des snapshots; si c'est vrai?,  j'aimerais bien savoir où est ce qu'une "smart copy" est enregistrée ???. merci d'avance pour votre réponse!!!  :emotion-21:
