Acronis True Image Home 2012 gives you an opportunity to undo the changes that were made to your files as a result of synchronization. If you found out that one of your files contains an undesirable change, you can view previous versions of this file and then choose and rollback to its correct version. See details in Reverting to a previous file version.
By default, this option is turned off. Acronis True Image Home 2012 starts to store versions of synced files from the moment you turn this option on.
All versions are stored in the Acronis Online storage which is accessible via the Internet. To use the Acronis online storage, you must have a subscription to the Online Backup service. If you do not have a subscription, a trial subscription with 250 GB of storage space will be automatically provided. See details in Subscription information.
The following automatic cleanup rules are applied to the versions stored in the Acronis Online storage:
The last version of a file can be deleted from the storage only manually and not as a result of automatic cleanup. Deleted versions cannot be restored.
When you turn off the option of storing versions, all the versions except the latest one are deleted from the server.
If you use a trial version of Acronis True Image Home 2012, all the stored versions including the latest one are deleted from the server when the trial period expires.
Each user turns the option on and manages file versions independently of other users. If you sync some data with a friend who uses different Acronis account, you decide for yourself whether you want to turn the option on or not. Version storages allocated on the server are also separate.
