Nakivo Backup Replication architecture and installation on TrueNAS – Part 1

Backup and Replication software have received strong mandates in organizations with enterprise mindsets and vision. But lower down the rung, small medium organizations are less invested in backup and replication software. These organizations know full well that they must backup, replicate and protect their servers, physical and virtual, and also new workloads in the clouds, given the threat of security breaches and ransomware is looming larger and larger all the time. But many are often put off by the cost of implementing and deploying a Backup and Replication software.

So I explored one of the lesser known backup and recovery software called Nakivo® Backup and Replication (NBR) and took the opportunity to build a backup and replication appliance in my homelab with TrueNAS®. My objective was to create a cost effective option for small medium organizations to enjoy enterprise-grade protection and recovery without the hefty price tag.

This blog, Part 1, writes about the architecture overview of Nakivo® and the installation of the NBR software in TrueNAS® to bake in and create the concept of a backup and replication appliance. Part 2, in a future blog post, will cover the administrative and operations usage of NBR.

Resilient Integrated Data Protection against Ransomware

Early in the year, I wrote about NAS systems being a high impact target for ransomware. I called NAS a goldmine for ransomware. This is still very true because NAS systems are the workhorses of many organizations. They serve files and folders and from it, the sharing and collaboration of Work.

Another common function for NAS systems is being a target for backups. In small medium organizations, backup software often direct their backups to a network drive in the network. Even for larger enterprise customers too, NAS is the common destination for backups.

Backup to NAS system

Typical NAS backup for small medium organizations.

Backup to Data Domain with NAS Protocols

Backup to Data Domain with NAS (NFS, CIFS) Protocols

Ransomware is obviously targeting the backup as another high impact target, with the potential to disrupt the rescue and the restoration of the work files and folders.

Rebooting Infrascale

[ Disclosure: I was invited by GestaltIT as a delegate to their Storage Field Day 19 event from Jan 22-24, 2020 in the Silicon Valley USA. My expenses, travel, accommodation and conference fees were covered by GestaltIT, the organizer and I was not obligated to blog or promote the vendors’ technologies to be presented at this event. The content of this blog is of my own opinions and views ]

Infrascale™ was relatively unknown for the Storage Field Day 19 delegates when they presented a few weeks ago in San Jose. Between 2015-2017, they have received several awards and accolades, including being in the Leaders quadrant for the 2017 Gartner Magic Quadrant for DR-as-a-Service.

I have known of Infrascale since 2016 as the BC and DR landscape was taking off back then, gravitating towards the cloud as a secondary platform for recovery.

ZFS Replication and Recovery with FreeNAS

We get requests to recover data from a secondary platform all the time. RPO (recovery point objective) of 30 minutes can be challenging to small to medium sized companies, especially if there is an SLA (service level agreement) to meet.

This week, my team and I took some time to create a FreeNAS replication demo for a potential client. I thought I document the whole thing about ZFS replication, the key steps to set it up and show how recovery is done.

ZFS Snapshots

ZFS replication relies on periodic ZFS snapshots. ZFS snapshot is an inherent feature from the ZFS file system, and often used as a point-in-time copy of the existing ZFS file system tree in memory. Once a snapshot has been triggered, either manually or on schedule (periodic), the file system tree and its metadata in the memory are committed to disk to ensure an updated and consistent state of the file system at all times.

To start, a running snapshot policy on a schedule must be in place. This snapshot policy can be on a specific dataset or zvol, or even the entire zpool. Yeah, I am using quite a few ZFS terminology here – zpool, zvol, dataset. You can read more about each of the structures and more here.

Once the ZFS replication task has been setup, every snapshot occurred in the snapshot policy is automatically duplicated and copied to the target ZFS dataset. Usually, the target ZFS dataset is on a secondary FreeNAS storage server, serving as a disaster recovery platform. Sending and receiving data in the snapshots rely on SSH service.

This is the network diagram explaining the FreeNAS ZFS replication setup.

The Dell EMC Data Bunker

[Preamble: I have been invited by  GestaltIT as a delegate to their TechFieldDay from Oct 17-19, 2018 in the Silicon Valley USA.

Another new announcement graced the Tech Field Day 17 delegates this week. Dell EMC Data Protection group announced their Cyber Recovery solution. The Cyber Recovery Vault solution and services is touted as the “The Last Line of Data Protection Defense against Cyber-Attacks” for the enterprise.

Security breaches and ransomware attacks have been rampant, and they are reeking havoc to organizations everywhere. These breaches and attacks cost businesses tens of millions, or even hundreds, and are capable of bring these businesses to their knees. One of the known practices is to corrupt backup metadata or catalogs, rendering operational recovery helpless before these perpetrators attack the primary data source. And there are times where the malicious and harmful agent could be dwelling in the organization’s network or servers for long period of times, launching and infecting primary images or gold copies of corporate data at the opportune time.

The Cyber Recovery (CR) solution from Dell EM focuses on Recovery of an Isolated Copy of the Data. The solution isolates strategic and mission critical secondary data and preserves the integrity and sanctity of the secondary data copy. Think of the CR solution as the data bunker, after doomsday has descended.

The CR solution is based on the Data Domain platforms. Describing from the diagram below, data backup occurs in the corporate network to a Data Domain appliance platform as the backup repository. This is just the usual daily backup, and is for operational recovery.

Commvault UDI – a new CPUU

[Preamble: I am a delegate of Storage Field Day 14. My expenses, travel and accommodation are paid for by GestaltIT, the organizer and I am not obligated to blog or promote the technologies presented at this event. The content of this blog is of my own opinions and views]

I am here at the Commvault GO 2017. Bob Hammer, Commvault’s CEO is on stage right now. He shares his wisdom and the message is clear. IT to DT. IT to DT? Yes, Information Technology to Data Technology. It is all about the DATA.

The data landscape has changed. The cloud has changed everything. And data is everywhere. This omnipresence of data presents new complexity and new challenges. It is great to get Commvault acknowledging and accepting this change and the challenges that come along with it, and introducing their HyperScale technology and their secret sauce – Universal Dynamic Index.

Falconstor – soaring to 7th heaven

I was invited to Falconstor version 7.0 launch to the media this morning at Sunway Resort Hotel.

I must admit that I am a fan of Falconstor from a business perspective because they have nifty solutions. Many big boys OEMed Falconstor’s VTL solutions such as EMC with its CDL (CLARiiON Disk Library) and Sun Microsystems virtual tape library solutions. Things have been changing. There are still OEM partnerships with HDS (with Falconstor VTL and FDS solutions), HP (with Falconstor NSS solution) and a few others, but Falconstor has been taking up a more aggressive stance with their new business model. They are definitely more direct with their approach and hence, it is high time we in the industry recognize Falconstor’s prowess.

The launch today is Falconstor version 7.0 suite of data recovery and storage enhancement solutions. Note that while the topic of their solutions were on data protection, I used data recovery, simply because the true objective of their solutions are on data recovery, doing what matters most to business – RECOVERY.

Falconstor version 7.0 family of products is divided into 3 pillars

  • Storage Virtualization – with Falconstor Network Storage Server (NSS)
  • Backup & Recovery – with Falconstor Continuous Data Protector (CDP)
  • Deduplication – with Falconstor Virtual Tape Library (VTL) and File-Interface Deduplication System (FDS)

NSS virtualizes heterogeneous storage platforms and sits in between the application servers, or virtualized servers. It simplifies disparate storage platforms by consolidating volumes and provides features such as thin provisioning and snapshots. In the new version, NSS now supports up to 1,000 snapshots per volume from the previous number of 255 snapshots. That is a 4x increase as the demand for data protection is greater than ever. This allows the protection granularity to be in the minutes, well meeting the RPO (Recovery Point Objectives) standard of the most demanding customers.

The NSS also replicates the snapshots to a secondary NSS platform at a DR to extend the company’s data resiliency and improves the business continuance factor for the organization.

In a revamp new algorithm in version 7.0, the Microscan technology used in the replication technology is now more potent and higher in performance. For the uninformed, Microscan, as quoted in the datasheet is:

MicroScan™, a patented FalconStor technology, minimizes the
amount of data transmitted by eliminating redundancies at the
application and file system layers. Rather than arbitrarily
transmitting entire blocks or pages (as is typical of other
replication solutions), MicroScan technology maps, identifies, and
transmits only unique disk drive sectors (512 bytes), reducing
network traffic by as much as 95%, in turn reducing remote
bandwidth requirements.

Another very strong feature of the NSS is the RecoverTrac, which is an automated DR technology. In business, business continuity and disaster recovery usually go hand-in-hand. Unfortunately, triggering either BC or DR or both is an expensive and resource-consuming exercise. But organizations have to prepare and therefore, a proper DR process must be tested and tested again.

I am a certified Business Continuity Planner, so I am fully aware of the beauty RecoverTrac brings to the organization. The ability to test non-intrusive, simulated DR, and find out the weak points of recovery is crucial and RecoverTrac brings that confidence of DR testing to the table. Furthermore, well-tested automated DR processes also eliminates human errors in DR recovery. And RecoverTrac also has the ability to track the logical relationships between different applications and computing resource, making this technology an invaluable tool in the DR coordinator’s arsenal.

The diagram below shows the NSS solution:

 

And NSS touts to be one true any storage platform to any storage platform over any protocol replication solution. Most vendors will have either FC or iSCSI or NAS protocols but I believe so far, only Falconstor offers all protocols in one solution.

Item #2 in the upgrade list is Falconstor’s CDP solution. Continuous Data Protection (CDP) is a very interesting area in data protection. CDP provides almost near-zero RTO/RPO solution on disk, and yet not many people are aware of the power of CDP.

About 5-6 years ago, CDP was hot and there were many start-ups in this area. Companies such Kashya (bought by EMC to become RecoverPoint), Mendocino, Revivio (gobbled up by Symantec) and StoneFly have either gone belly up or gobbled up by bigger boys in the industry. Only a few remained, and Falconstor CDP is one of the true survivors in this area.

CDP should be given more credit because there are always demand for very granular data protection. In fact, I sincerely believe that both CDP, snapshots and snapshot replication are the real flagships of data protection today and the future because data protection using the traditional backup method, in a periodic and less frequent manner, is no longer adequate. And the fact that backup is generating more and more data to keep is truly not helping.

Falconstor CDP has the HyperTrac™ Backup Accelerator (HyperTrac) works in conjunction with FalconStor Continuous Data Protector (CDP) and FalconStor Network Storage Server (NSS) to increase tape backup speed, eliminate backup windows, and offload processing from application servers. A quick glimpse of HyperTrac technology is shown below:

 

In the Deduplication pillar, there were upgrades to both Falconstor VTL and Falconstor FDS. As I said earlier, CDP, snapshots and replication of the snapshot are already becoming the data protection of this new generation of storage solutions. Coupled with deduplication, data protection is made more significant because it makes smart noodles to keep one copy of the same old files, over and over again.

Falconstor File-Interface Deduplication Systems (FDS) addresses the requirement to storage more effectively, efficiently, economically. Its Single Instance Repository (SIR) technology has now been enhanced as a global deduplication repository, giving it the ability to truly store a single copy of the object. Previously, FDS was not able to recognize duplicated objects in a different controller. FDS also has improved its algorithms, driving performance up to 30TB/hour and is able to deliver a higher deduplication ratio.

 

In addition to the NAS interface, the FDS solution now has a tighter integration with the Symantec Open Storage Technology (OST) protocol.

The Falconstor VTL is widely OEM by many partners and remains one of the most popular VTL solutions in the market. VTL is also enhanced significantly in this upgrade and not surprisingly, the VTL solution from Falconstor is strengthened by its near-seamless integration with the other solutions in their stable. The VTL solution now supports up to 1 petabyte usable capacity.

 

Falconstor has always been very focused in the backup and data recovery space and has done well favourably with Gartner. In January of 2011, Gartner has release their Magic Quadrant report for Enterprise Disk-based Backup and Recovery, and Falconstor was positioned as one of the Visionaries in this space. Below is the magic quadrant:

 

As their business model changes to a more direct approach, it won’t be long before you seen Falconstor move into the Leader quadrant. They will be soaring, like a Falcon.
