NetApp says that Snapshot is included into Essentials Bundle.
But how to create snapshots from SAN LUN's if there is no snapdrive?
Any ideas? Without stopping the LUN and taking snaps.
You can script pretty much any OS to flush the buffers to disk & then take a snapshot on the filer - SnapDrive does the same thing.
Is that any example available for Windows Server?
Have a look at NetApp DataONTAP PowerShell Module for the NetApp part:
Vssadmin command can be used for creating VSS snapshot at the OS layer, followed by NetApp snapshot. An example here:
It is possible to take snapshots, but what if i have to restore something from that LUN? Am I able to map this "Snap"LUN to windows? Without flexclone and snaprestore.
Yes - see “lun clone”.
So i have to wait the time to copy all blocks of a 2TB lun?
Is that only one way? Is that possible to map the LUN without clone it?
LUN clone is a "thin copy" operation, like FlexClone.
