Snapshot-based backups greatly reduce the time during which the database and applications are unavailable because snapshots provide logical copies of the file system at a given point in time without requiring a physical copy of the entire file system. Additionally, the frozen file system can be cloned to another virtual machine immediately into active service since snapshots capture the state of the file system at a specific point in time, which allows for quick deployment of a cloned virtual machine.
A and D
agree D
Not D, if the snapshot is writable, you can run mysqld off of it, no need to copy.
I think is A and C. Snapshot-based backups greatly reduce time during which the database and applications are unavailable. This is because snapshots provide logical copies of the file system at a given point in time, without requiring a physical copy of the entire file system. The frozen file system can be cloned to another virtual machine immediately into active service. This is implied by the nature of snapshot backups, as they capture the state of the file system at a specific point in time.
B and C I think.
