Acronis Backup & Recovery Online is a service that enables you to back up data to Acronis Online Backup Storage. To use this service, you need to buy a subscription that determines the amount of storage space reserved for your backups (storage quota) and how long the online service will be available to you.
Examples of subscriptions:
A 1 TB/ 1 year volume subscription means that you can back up data from an unlimited number of physical and/or virtual machines, for a period of one year. The backups can occupy no more than one terabyte.
A 250 GB/ 1 year workstation subscription means that you can back up data from a machine running a non-server Windows operating system, for a period of one year. The backups can occupy no more than 250 GB.
