Final answer:
In data provisioning, two methods of replication are Snapshot Replication, which copies data at specific intervals, and Transactional Replication, which duplicates changes in real-time.
Step-by-step explanation:
Methods of Data Replication
Data replication is a strategy used in computing to ensure that consistent copies of data are held in different locations. This is done to increase data reliability, availability, and accessibility. Two common methods of replication associated with data provisioning are:
- Snapshot Replication: This method involves copying data from the source to the destination at specific points in time. Snapshots are taken at regular intervals, creating full copies of the data that can be used for recovery or analysis. The main benefit of this method is that it provides a clear and concise historical reference point of the data.
- Transactional Replication: This method focuses on ensuring consistency by replicating individual transactions as they occur. Every time a change is made to the source data, that exact change is duplicated on the destination system. This approach is highly beneficial for systems that require near real-time data availability and strict consistency.
Understanding these replication techniques is crucial for database administrators and IT professionals who are tasked with managing data effectively across multiple systems.
