391 Copyright © Acronis, Inc., 2000-2010 VMware ESX(i) 4.0 and 4.1(Host-based backup is available only for paid licenses of VMware ESXi.) Windows Server 2008/2008 R2 (x64) with Hyper-V Microsoft Hyper-V Server 2008/2008 R2If your backups are likely to exceed the storage quota for this type of subscription, you may want touse a subscription with larger storage quota. For example, you can use a server subscription or asubscription for virtual machines on a workstation. Or you can use a subscription for virtual machineson a server which is not a virtualization server.The inverse usage is not possible. You cannot back up a server using a workstation subscription. Ifyou try to back up ESX(i) or Hyper-V virtual machines from the host that uses a server subscription,the backup will fail. With a server subscription, you can only back up the Windows host. With asubscription for virtual machines, you can back up both the Windows host and its virtual machines.Trial subscriptionsYou can get one free workstation subscription, server subscription, or subscription for virtualmachines per account. The storage quota of the trial subscription is equal to that of the standardsubscription. The subscription period is limited to 2 months.Obtaining a trial subscription is possible until you buy a paid subscription. You can use a trialsubscription along with paid ones. The same expiration rules apply to trial and paid subscriptions.To continue using the service after the trial subscription expires, buy the same type subscription andrenew the trial subscription specifying the paid subscription. Your backed up data will be kept online.Regular backups of your machines will continue uninterrupted. The service will not need to perform anew full backup.8.4 Activating online backup subscriptionsTo be able to back up a machine to the online storage, you need to purchase and activate asubscription to the Acronis Backup & Recovery 10 Online service. You can purchase subscriptions onthe Acronis Web site or from an Acronis reseller.Before activating a subscription, please take into account the following considerations: As soon as a subscription is activated, its subscription period starts. To avoid losing subscriptiontime, activate the subscription only when you are ready to back up the machine. If a machine already has a subscription, the new subscription will replace the old one. You canreassign the old subscription to a different machine—see “Reassigning an activated subscription”later in this section.8.4.1 Activating subscriptionsTo begin with, make sure that the machines whose subscriptions you want to activate are registeredon the management server and available (turned on).To activate subscriptions1.
