As you know, Android system has two update mechanisms; A/B seamless updates and non-A/B updates. A/B partition system, which introcuded with Android 7.0 (Nougat) in 2016, was updated by Google years later. This is a system that will likely be enforced with Android 13. To reduce code complexity and improve the update process, in Android 11 the two mechanisms are combined via Virtual A/B, bringing seamless updates to all devices with minimal storage cost, this provides Virtual A/B compression option to compress snapshot partitions.

System pdates are seamless like A/B updates. Virtual A/B updates minimize the time that a device is offline and unusable, and can be rolled back. If the new OS fails to boot, devices automatically rollback to previous version. Virtual A/B updates uses minimum of extra space by duplicating only the partitions that are used by the bootloader. Other updateable partitions are snapshotted.
