Snapshot
Snapshots for a full backup are not the same as snapshots for virtual machines, where they freeze the state of the VM in a point in time. A snapshot for a full backup is when it is committed without powering off or temporarily suspending the VM. This is also known as a live backup. Since a backup occurs while the VM is running, there is no downtime for this mode, but it also has the longest backup time. On rare occasions, files in use can cause backup errors due to file locks.
