Laws differ from theories because laws do not provide an explanation for how things work or could possibly work. A law describes what happens or needs to happen under certain conditions. A law can predict what will happen as long as those conditions are met. <span>For the purposes of this discussion, a "law" is a rule that has been formalised by repeated testing. It is also a generalisation. A theory, on the other hand, is an explanation for an observation that is supported by a large body of evidence. </span>

Answer:
The advantages and disadvantages of recovery strategies are described.
Explanation:
1. Weekly full server backups with daily incremental backups: It is recommended to run full copies periodically for example weekly and between copy and full copy make incremental or differential copies. Daily full server backups: It is not recommended to make copies on the same server where the information is located. Disadvantage larger storage space.
2. Daily full server backups with hourly incremental backups: Less storage space than full or differential copy. Minor copy window. Disadvantage - if any dependent copy fails, the copy cannot be restored.
3. Redundant array of independent (or inexpensive) disks (RAID) storage devices with periodic full backups: RAID allows you to store the same data redundantly (in multiple paces) in a balanced way to improve overall performance. RAID disk drives are used frequently on servers but aren't generally necessary for personal computers.
4. Replicated databases and folders on high-availability alternate servers: Easy recovery. You have all the data copied.
