Vaults are places where you can directly upload files/folders from anywhere to your Zoolz account, with a simple drag-drop for those files/folders. You can also copy any of your backed up files/folders to the Vaults for sharing purposes.
There are two type of Vaults: Instant Vault and Cold Vault.
If you you are a Zoolz Business user, you can have the both types of Vaults added to your Zoolz account.
If you you are a Zoolz Home user, you can only have Instant Vaults added to your Zoolz account.
