 # Snapshots
 
-Snapshot of an instance is an exact state of a VM in the moment when the snapshot was taken. Snapshots can be done on running aas well as on turned-off instances. They are useful for example when significant system changes are needed.They provide an easy roll-back option to the state before the changes. The snapshots cannot be considered a replacement for a system back-up. The snapshots neither provide a protection from a hardware failure.

 Při replikaci se průběžně kopíruje obsah \(respektive probíhající změny\) virtuálního serveru na oddělené úložiště. V případě poruchy hardwaru, na kteréxm virtuální server běží, je možné virtuální server nastartovat z takto udržované repliky. Tato replika není zcela identická s původním virtuálním serverem. Je v ní uložen snímek provozovaného virtuálního serveru, s určitým \(obvykle několikaminutovým\) zpožděním oproti aktuálnímu stavu provozovaného virtuálního serveru. Jedná se o asynchronní proces.
