In the absence of virtual machines, migration between physical machines relies on system backup and recovery techniques. Back up the operating system and application status on the source host in real time, then connect the storage media to the target host and finally restore the system on the target host.

The security of server data has always been the most serious of the server's daily management. Linux Server virtualization is known for its highly reliable operating systems, although system failures can still occur. May be due to hardware failure, power outages, or other unforeseen problems. More commonly these problems come from human errors, improper changes, or even deletion of important files.Restoring

SQL Server also does not provide backup and restore operations to the tempdb database. Protecting the model database ensures that a good tempdb database will be available at the next boot. As a result, the tempdb database is protected
