of cloud space. Recovery and restoration Acronis Cyber Protect Home Office allows users to restore files from a full disk or a file-based archive using either a preinstallation media with Acronis on it or from within the user interface of the program. If protected system files are restored (e.g. restoring an entire system to an earlier state), the system restarts to perform the recovery operation. Users may also mount a backup archive, which allows users to browse the contents of the archive in a manner similar to browsing any other disk drive. Disk cloning The software can clone the contents from one physical storage device (e.g. SSD, HDD or NVMe) to another drive. The drive does not need to be formatted before data can be cloned to it and may be smaller in size than the source disk but the amount of space on the disk must be at least the size of the amount of data being cloned. Cloning aims to preserve the disk metadata. For example, disk cloning is useful for installing a larger disk in a computer or replacing a hard disk drive with a solid state drive. Crucial recommends using a preinstallation media of Acronis to perform the clone to avoid possible cloning failures due to partitions being inaccessible. Some hard disk manufacturers including Western Digital, Intel and Seagate provide customized variants of Acronis True Image with their drives that allows the user to clone their existing disk to another disk, typically of the same manufacturer. Reverting changes Acronis allows users to protect selected disk drives from unintended changes and revert them if the change is undesired. This can be used instead of virtual machines to create stable and secure environments that can be quickly reverted from within the software. Limitations Possible incompatibility between versions Prior to Acronis True Image 2020, the backup archives were stored using a proprietary format with a .tib file extension on Windows systems. Due to this, compatibility is not guaranteed between products that are not within the same version. Older versions of the software cannot read backup archives created using a newer version. Unwanted advertisements One limitation of the software is the inability to disable taskbar popups marketing upgrades and new products from the developer. The notification will grab focus (i.e. will interrupt a full screen game or movie) and each advertisement must be disabled individually. The company currently offers no
