Yes, data protection in storage arrays has been available for many years - maybe the pioneer 'back in the day' was a very well know NAS provider who heavily used snapshots to protect data held on the storage appliance. And even before snapshots, tape has played a key role in data centre and the protection of data - who remembers time-consuming NDMP backups? And then after both of these, we witnessed the birth of deduplication, which first made its arrival in the form of a purpose-built backup appliance.
Fast forward to 2021 and we all have the same pressures as before in terms of ensuring data can be restored as soon as possible - sometimes down to a system error, but most likely due to a user restore request. However, the world we live in now is moving faster than ever, meaning expectation are even higher, but to add to the complexity - data doesn't just reside in a central data centre anymore and this means IT teams need to ensure the protection and recoverability of data wherever it resides. The game is on for all IT departments to ensure the best possible data protection strategies to be implemented...
Obviously, the main reason for solid data protection and DR strategies is to prevent downtime or keep it to an absolute minimum. A recent study by Enterprise Strategy Group (ESG), who researched the implications of application downtime, found that loss of revenue had the most impact to an organisation where application downtime or lost data has occurred. Just another pressure on the shoulders of IT teams.
We're sure you're already fully aware of the pressures discussed, but we quite often find that data protection can be very subject to 'if it isn't broke, don't fix it' or 'we have more pressing projects on the go'. What if you could implement a storage system with data protection built into its fabric, with a validated backup infrastructure for 'belt and braces' - meaning you don't have to solely rely on your backup infrastructure all the time? If you'd like to learn more, then read on...
Let's look at the details, advice and options to create an enterprise data protection strategy
Firstly, it's important to transform your thinking from backup to restore. Yes, thinking about backup is logical - more data is backed up than is restored. But given the increasing business value of data and the cost of downtime then restore is more critical than backup. It is wise to identify your mission-critical data and associated costs to your business of not having that data available - to evaluate technologies that can meet the restore SLAs required long term is a great way to look at this.
Whenever we ask at "how long will it take to backup" and how "quickly can we recover" then we need to work out RPO & RTO requirements:
To help meet RPO & RTO objectives, let's consider the available options, which have been predominantly utilised.
Replication Technologies - Storage vendors have been providing these technologies for some time. This allows storage to take copies while in production and send those copies to alternative storage, often in a different location. Integration is also provided for the applications, allowing the application to use the alternative copy if a failure occurs.
Hardware Snapshots - Provided by hardware array vendors as a very quick way of providing a recoverable copy of an application. Snapshots, also known as or clones, can be created in seconds with little performance impact on the application, and they are typically attached to the storage array from which they’re created. Multiple snapshots can be generated throughout the day, which greatly improves the recovery point objective.
Disk-based Backup: As discussed already, disk-based backup has been in use for many years - its uptake started with the advent of cost-effective SATA disks in the early 2000’s. This allowed IT teams to introduce “disk” staging, where backups would go to disk first and then be moved to tape for long-term storage.
Disk-based Backup Appliances: After the significant use of SATA disk for backup, the backup environment was disrupted again in the mid to late 2000’s by Purpose-Built Backup Appliances (PBBAs). These appliances delivered deduplication which enabled IT departments to store smaller amounts of backup data while protecting remote offices efficiently - all due to deduplication.
Tape: Tape technology has long been the mainstay of Enterprise data protection. Before backup appliances, data would be sent over a network from primary storage and written to tape. Often tapes were duplicated and one or more copies were shipped off-site to a second location. More lately tape has become the 'belt and braces' & 'last resort copy' - but a trusted one at that.
Public Cloud: Today, cloud usage is on the agenda of every CTO. One of the most common use cases of public cloud is long term repository for backup data. Backup software vendors have built various layers of integration with public cloud vendors so backups can be sent to the cloud for storage. In certain scenarios, the public cloud is replacing tape as a means of providing a disaster recovery copy.
The above options each have their own advantages and disadvantages, in regards to RPO/RTO - If you want to deep dive into this, let's set up a call with a COOLSPIRiT expert!
So, what if you could get the best of all worlds from the above? With technology from Pure Storage, you can...
While legacy storage solutions have been known for excessive maintenance renewals, operational complexity, disruptive upgrades with forced data migrations, and other flaws, Pure has always focused on doing things differently - and getting it right. Data Protection is a prime example. Some vendors charge extra (and still do) for critical protection features like synchronous replication. The idea of charging extra for “luxury” features seem to be acceptable within some vendors - for Pure it isn't. Pure has never charged extra for modern data protection features. They’re always included; as a customer, you can access any new features in the next release with standard maintenance. For example, when ActiveDR continuous replication was delivered through the FlashArray Purity operating environment - it was available free - Just kick off a simple software update to start using that new functionality. No additional costs and no service disruption during the upgrade.
Let's look at the details of what Pure offer 'out-of-the-box', in regards to data protection requirements, and how they do it:
All the above is delivered by the Pure1 Management system, which includes predictive support & Purity REST APIs for automation.
As you can see, with technology from Pure you have all the bases covered for your data protection requirements - while allowing consolidation of all your ageing systems into a modern data platform.
However, before we move on let's just take a quick look at an example of why data protection shouldn't be complicated with the flexible architecture of Pure's FlashArray. We're sure you have asked yourself before - "Why are some data-protection operations so difficult to set up and manage?". FlashArray is simple. You configure ActiveDR like this:
Data begins to replicate as soon as the setup is complete. After the initial baseline copy, it automatically shifts into continuous replication mode for any new data writes. Done. With legacy storage vendors, you may have found yourself spending more time trying to wade through the setup documentation and getting nowhere than it would take you to configure ActiveDR from start to finish.
If you’re tired of struggling with enterprise storage data protection that’s expensive and complicated, maybe it’s with considering technology from Pure...
Finally, let's look out one step further... Protect your Pure & Public Cloud infrastructure with COOLSPIRiT's GUARDiAN Appliances, powered by Commvault...
