Replication is a key technology for disaster recovery, and often works in combination with data deduplication, virtual servers, or the cloud to carry out its DR role. In this tutorial on data replication and disaster recovery, learn how to choose the best replication product, the differences between host, array, and network based data replication, and about how new technologies like data deduplication and virtual servers are changing replication and disaster recovery. DATA REPLICATION AND IT DISASTER RECOVERY TECHNOLOGY TUTORIAL TABLE OF CONTENTS Choosing a replication product for disaster recovery  Array, host, and network based replication  Data deduplication and data replication  Virtual servers and data replication Cloud storage and data replication CHOOSING A DATA REPLICATION PRODUCT Several factors determine what type of data replication product is best for an organization. There are two types of data replication products synchronous or asynchronous. Synchronous replication writes data to the primary and secondary sites at the same time. With asynchronous replication, there is a delay before the data gets written to the secondary site. Both types have advantages and disadvantages. While data is always current between sites with synchronous replication, it is more expensive than asynchronous replication, introduces latency that slows down the primary application, and only works over distances of 5. Synchronous replication is preferred for applications with low recovery time objectives RTOs that cant abide data loss. Because asynchronous replication is designed to work over distances and requires less bandwidth, it is often a better option for disaster recovery. However, asynchronous replication risks a loss of data during a system outage because data at the target device isnt up to date with the source data.

ARRAY, HOST, AND NETWORK BASED REPLICATION Another differentiator is where the replication takes places. C281' alt='Equallogic Hit Kit Windows' title='Equallogic Hit Kit Windows' />Replication occurs in one of three places in the storage array, at the host server, or in the network. Most replication still occurs at the array, although that is changing as host and network based options improve. Storage array based replication Most enterprise data storage vendors include replication software on their high end and midrange storage arrays.

When you have some VMs with thin provisioned disks, you may have noticed that these will continue to grow, and never shrink, even after cleaning out data from within. PowerShell v2. 0 was completed and released to manufacturing in August 2009, as an integral part of Windows 7 and Windows Server 2008 R2. Versions of PowerShell for.

Copy for synchronous replication and IBM Corp. Global Mirror for asynchronous replication and IBM Metro Mirror for synchronous replication. The main drawback of array based replication is lack of heterogeneous support. Except for HDS, which supports other vendors storage with its USP V systems, vendors software only allows replication between like arrays. EMC wont even allow replication between high end Symmetrix and midrange Clariion systems.

Host based replication Host based replication software runs on standard servers, making it the cheapest and easiest type of replication to manage. However, it does tax the server CPU.

Disk array based replication usually replicates only between the same type of array, while network based and array based replication works across storage platforms. Another difference is host replication only supports asynchronous replication, while array and network replication can be asynchronous or synchronous.

DATA DEDUPLICATION AND REPLICATION Data deduplication the hottest technology in data backup today is often combined with replication for disaster recovery purposes. Deduplication reduces the amount of data that gets replicated and lowers the bandwidth requirement to copy data offsite. Leading deduplication software vendors EMCData Domain, Falcon. Stor Software, IBMDiligent, Quantum Corp. Sepaton Inc. have added or upgraded their replication capabilities this year. There are some drawbacks to the dedupereplication combination. Inline deduplication, which takes place while data is being written to disk, can impact backup performance. Post process dedupe, which takes place after the backup completes, can delay replication. Still, data that is deduplicated and replicated offsite can be recovered much faster than data backed up to tapes and stored offsite for disaster recovery. WAN optimization devices such as those from Cisco Systems, Blue Coat Systems, Riverbed Technology and Silver Peak Systems also use data deduplication to complement replication over the WAN for DR.

VIRTUAL SERVERS AND DATA REPLICATION Server virtualization is a driver for disaster recovery because virtualization reduces the number of servers required for a disaster recovery site. Virtual servers are stored as files or virtual machine VM images on the host, and can be moved by copying the VM image file and booting it on another host while physical servers require the same hardware at the DR site. Tools for replicating virtual machines include PHD Virtual es. Cabin In The Sky Nancy Wilson. Xpress, Vizioncore v. Replicator or VMware Site Recovery Manager if your array supports it or tools built into applications such as Oracle that replicate data between servers.

CLOUD STORAGE AND DATA REPLICATION The cloud also fits with replication, because it can remove cost and complexity from disaster recovery.
