Site	Condition	Scenario example
Primary	Modify VHD when VM is turned off	Mount/modify VHD outside the VM, Edit disk, Offline patching
Primary	Size of tracking log files > 50% of total VHD size for a VM	Network outage causes logs to accumulate
Primary	Write failure to tracking log file	VHD and logs are on SMB and connectivity to the SMB storage is flaky.
Primary	Tracking log file is not closed gracefully	Host crash with primary VM running. Applicable to VMs in a cluster also.
Primary	Reverting the volume to an older point in timeReverting the VM to an older snapshot	Volume/snapshot backup and restore
Secondary	Out-of-sequence or Invalid log file is applied	Restoring a backed-up copy of the Replica VM
