Deduplicated Backup Storage – 3 Modes of Operation

Good post by Brian Seltzer (thank you)

The move away from tape backups towards disk-based backups has been going on for a while now.  Storing backups on disk generally means faster backups and faster restores.  However, disk isn’t as cheap as tape, and storing many terabytes or even petabytes of data on disk can lead to sprawling storage systems.  To reduce the cost and physical size of backup disk, backup storage is commonly deduplicated.  This can have a pretty dramatic impact on the size of backed up data, especially if your retention period include multiple full backups.

Designing Primary Storage to Ease the Backup Burden

Good post by George Crump (thank you)

When IT planners map out their primary storage architectures they typically focus on how well the system will perform, how far it will scale and how reliable it will be. Data protection, that process that guards against corruption or system failure in primary storage or even a site disaster, is too often a secondary consideration, and often made by someone else. But what if the primary storage system could be designed to protect itself from these occurrences? Would that make it possible to simplify or even eliminate the data protection process altogether?

Data Protection: All Starts with an Architecture

Post by Edward Haletky (thank you)

At The Virtualization Practice, we have systems running in the cloud as well as on-premises. We run a 100% virtualized environment, with plenty of data protection, backup, and recovery options. These are all stitched together using one architecture: an architecture developed through painful personal experiences. We just had an interesting failure—nothing catastrophic, but it could have been, without the proper mindset and architecture around data protection. Data protection these days does not just mean backup and recovery, but also prevention and redundancy.

StrongBox Archive NAS solves problem of Long-term Unstructured Data Storage

Good post by Eric Slack (thank you)

Unstructured data is burying companies’ storage infrastructures. According to Gartner, files comprise 80 percent of all data, and its growth rate in enterprises will exceed 800% in five years. Compounding this problem is the need to store these data for longer periods. “Long term” used to mean 15 years, now 20 years is not uncommon, and for many companies, “forever” is becoming the norm. What’s needed is cost-effective storage, a solution that’s simple to use but able to handle the challenge of long-term data retention for unstructured data.

5 reasons your Storage Snapshot aren’t working

Whitepaper from CommVault (thank you)

Snapshot-based data protection solutions were supposed to solve our backup challenges, weren’t they? Then why are your backups still broken? If your snapshots are manually-managed or of the “build-it- yourself” variety, there may be several reasons that they aren’t working very well.

Cloud Integrated Backup and DR

Post by Colm Keegan (thank you)

The best way to ensure data and application recoverability is to conduct frequent DR testing. The problem is that many organizations rarely, if ever, perform DR testing because it is time consuming, expensive and often it has limited value because the tests are not “real world”. But if there was a way to integrate simple and effective DR testing into the backup environment, this could give businesses a cost-effective solution to test application recoverability. Moreover, if the backup environment could be further leveraged to facilitate near instantaneous application fail-over capabilities into the cloud with production level performance, this would significantly bolster business application availability and service levels.

DR options of VMware vSphere Data Protection (VDP)

Post by Vladan Seget (thank you)

In the past I have received few questions on VDP resiliency. Users usually like the “appliance” approach when it comes to backup software, but they want to be sure that they can take steps to get back in business if something gets wrong. Many things can happen to a VM don’t you think?

In addition, if you’re running your vCenter as a VM, I’ll also discuss an option when even if vCenter is unavailable, you can still use VDP to restore a VM from the backup repository.

The promise of next-generation WAN optimization

Good post by Enrico Signoretti (thank you)

Bandwidth, throughput, and latency aren’t issues when you are within the boundaries of a data center, but things drastically change when you have to move data over a distance. Applications are designed to process data and provide results as fast as possible, because users and business processes now require instant access to resources of all kinds. This is not easy to accomplish when data is physically far from where it is needed.

Cloud-scale Object Storage – where do you store the cloud itself?

Post by Eric Slack (thank you)

“The Cloud”, a ubiquitous term for near limitless storage and compute capacity, may seem like a fantasy to users but the infrastructure challenges it brings are very real indeed. Just ask the ‘hyper-scale’ companies that have developed their own systems to support this explosion of data stoked by internet and the Internet of Things. Scale-out, object-based storage architectures are ideal for these unstructured data sets but the commercially available solutions cloud providers and enterprise companies must use have limits. Now “Himalaya”, the latest storage architecture from Amplidata, promises to keep the object storage cloud ahead of the data growth curve.

VMware Offers Disaster Recovery As A Service

Post by Charles Babcock (thank you)

VMware disaster recovery service lets customers automatically replicate business systems and data in one of VMware’s five vCloud Hybrid Service datacenters.

VMware on Tuesday launched disaster-recovery-as-a-service from its vCloud Hybrid Service’s five datacenters. For VMware customers, it will offer an integrated way to implement disaster recovery for business-critical virtualized systems without needing to contract for a physical recovery site or buy VMware’s vCenter Site Recovery Manager.
