What is array-based replication?
Array-based replication is a type of data replication, which is the process of copying data via a storage-based snapshot and then replicating that snapshot data to store in additional sites.
What is the difference between array-based and host-based replication?
Array-based replication takes place in the storage array and network-based replication requires adding an appliance or intelligent switch. Host-based replication is less expensive than the other two options and works with any type of storage.
What is vmware array-based replication?
You can replicate virtual machines by using either array-based replication, vSphere Replication, or a combination of both….VMware Pages.
Characteristics | Array-Based Replication | vSphere Replication |
---|---|---|
Type | Replication using the storage layer. | Replication using the host or vSphere layer. |
What are the three replication strategies?
Data Replication Strategies
- Strategy 1: Log-Based Data Replication.
- Strategy 2: Full Table Data Replication.
- Strategy 3: Key-Based Incremental Data Replication.
What are the different types of replication?
What are the types of data replication?
- Full-table replication.
- Snapshot replication.
- Merge replication.
- Key-based incremental replication.
- Transactional replication.
- Log-based incremental replication.
What is storage based replication?
Storage-based data replication uses software installed on the storage device to manage the replication. Such software is specific to your particular storage device. Always refer to the documentation that shipped with your storage device when configuring storage-based data replication.
What is storage replication?
Data replication is the process of copying data from one location to another. The technology helps an organization possess up-to-date copies of its data in the event of a disaster. Replication can take place over a storage area network, local area network or local wide area network, as well as to the cloud.
What were the two techniques in host based local replication?
Host-based replication is a storage-agnostic and uses server resources. The other two data replication methods- array and network are OS-agnostic, a characteristic that a Host-based Replication methodology lacks. Furthermore, the host-based implementation adds fewer points of overhead to the servers’ CPU application.
What is the difference between SRM and vSphere replication?
vSphere Replication can be used independently or included in the VMware Site Recovery Manager (SRM) for disaster recovery plans. vSphere Replication license is included in vSphere Enterprise Plus, while SRM is an independent product and is a per VM or per CPU (as part of vCloud Suite Enterprise) license.
What is the use of SRM in VMware?
VMware Site Recovery Manager (SRM) provides policy-based management, minimizes downtime in case of disasters via automated orchestration, and enables nondisruptive testing of your disaster recovery plans.
What are types of replication?
Types of data replication
- Full table replication.
- Transactional replication.
- Snapshot replication.
- Merge replication.
- Key-based incremental replication.
What are the two types of replication?
Types of Replication: Snapshot replication sends the entire data set to the subscriber. Transactional replication only sends modifications to the data.
