Today, we’re not going to talk about why you should protect your data. Because you know you should. In this article, we’ll discuss the different data backup options available, and the ideal software, skills and storage package for you.

In this article, we’ll discuss the different data backup options available, and the ideal software, skills and storage package for you.

Introduction

In the backup world, we can identify two major non-exclusive options for running backups:
Enterprise Backup Solutions and Specialised Backup.

Enterprise Backup Solutions are software capable of executing multiple backups from different sources to a wide choice of destinations. They usually have a very user-friendly User Interface/Command-Line Interface, powerful scheduling capabilities, a range of flexible features, and come with compliance and certifications. They provide extensive support, with large communities you can rely on in the long term.

On the other hand, some applications and/or databases have their own Specialised Backup mechanism. They’re optimised, efficient and extremely popular due to their high performance and, quite often, they don’t need additional licences. However, very often you need to rely on the application/database administrator to take care of the backups.

To summarise:

• Enterprise Backup Solutions are fairly universal, can easily support a company-wide backup strategy, are user-friendly and can meet detailed pre-requisites.
• Specialised Backups are high performance and low cost which is appealing, but they can be difficult to use within a global backup strategy and administrators require specific knowledge.

As well as the tool used to move data, we must consider that data has a source and a destination. Keeping in mind the 3-2-1 rule (3 copies of your data (your production data and 2 backup copies) on 2 different media (disk and tape for example) with 1 copy off-site for disaster recovery), and the amount of sources in a modern IT system, both the choice of software solution and hardware platform used to store the backups must meet both the Global Backup Strategy and… your budget. There is also 3-2-1-1-0 backup strategy, which is another option. After all, even if the technical possibilities are infinite, the budget isn’t.

Enterprise Backup Solutions

So, let’s look at the most practical choices you can make to protect your precious data, whilst not having to rob a bank or ten. And to be honest, we’re mainly going to be looking at cloud services. Not just because we’re a cloud services company, but because cloud storage makes a lot of sense. We’ll demonstrate why.

There are numerous Enterprise Backup Solutions on the market and some have been around for a while. You’ve probably used one, and you’re probably still using that same one today. Why? Because you developed expertise in it, and you built your backup strategy based on its features and recommendations. And that makes sense. Your staff’s experience and skills should never be discounted when investigating opportunities for expanding your backup strategy for new workloads or changing to a cloud service. But very often, this expertise translates very easily to new systems, thanks to the use of standard vocabulary and similar mechanisms. So changing to a new Enterprise Backup Solution shouldn’t be too frightening, as expertise is rarely lost; but usually expanded.

Today, all Enterprise Backup Software supports cloud backup. Whether it’s from the cloud or to the cloud. And it doesn’t come as a surprise, as a lot of workloads are in the cloud – and backups too.
Remember the 3-2-1 rule? The cloud is particularly good for storing your off-site copy given that there are hosting locations all over the world.

OVHcloud Enterprise Backup Solutions

At OVHcloud, our IaaS products are compatible with all major Enterprise Backup Software, and some, like Veeam and HYCU, are even certified to run on our Enterprise platforms. And we also provide the adequate licences so you don’t have to use yet another provider.

You can pair Veeam/HYCU solutions with nearly any Operating System/application and benefit from advanced integration with VMware and Nutanix hypervisors. They have certified compatibility with Network File System / Common Internet File System /Object Storage and you can even add features to improve security.

It’s slightly outside the scope of this article, but our Managed VMware platform even has a Zerto option, allowing you to add replication to the highly recommended backups.

Our Public Cloud instances can be protected using snapshots and backups. All our Bare Metal servers include an external storage of 500GB which can used for your backup. This storage can be extended by up to 10TB.

Other Enterprise Backup Solutions

If you want more control over your backup strategy, leveraging your expertise and fitting it to your specific requirements, it is possible to build your own backup infrastructure with OVHcloud.

 All the major players in the Enterprise Backup market are compatible and already used by OVHcloud’s customers. To mention but a few: Veeam, HYCU, Datamotive, Nakivo, Veritas Technologies, Scality, CommVault, Rubrik, Acronis and Cohesity.

Open-Source Backup Solutions

And of course, if you’d rather use open-source software, Bacula is a perfectly viable option, or the simple but robust rsync. After all, if you just need to keep a reasonably updated copy of your data somewhere else, the simplest tool can often do the job. There’s many open-source options…

Specialised Backup Solutions

Kubernetes workloads

In the Cloud Native / Public Cloud / PaaS environment, you have access to and compatibility with the main players too:

• Velero
• CloudCasa
• TrilioVault
• Veeam Kasten
• and many others.

Application/Database workloads

But what if you use specific application/database mechanisms?
Given that our promise is to be open, agnostic and reversible, we do not block third party software from interacting with your data. So as long as you have the expertise to install and manage them, you can use them and make the most of our large storage portfolio.

Many solutions integrate a mechanism from, for example, pre-backup and post-backup to launch backup of your databases. Of course, if you use your databases with our VMware by Broadcom and/or Nutanix offer, you can rely on Veeam Enterprise and HYCU.

As specified earlier, all major players in the Enterprise backup Software have modules for database protection: Nakivo, Veritas Technologies, Scality, CommVault, Rubrik, Acronis and Cohesity

OVHcloud PaaS Backup

Our Public Cloud instances can be protected using snapshots and backups and our Managed Kubernetes are compatible with several industry leading backup software such as Velero, Triliovault and CloudCasa.

Here is the recap’ of how our Public Cloud Managed products are protected and your options:

SaaS Backup and Solutions

When we’re talking about cloud and Specialised Backup, we can’t forget to mention the SaaS offers. As much as they’re convenient, affordable and widely available, making sure that your data is safe is not always included in the contract. It’s always worth researching this before committing, or you might discover unsuspected charges for your backup.

At OVHcloud, we have a large portfolio of partners who can help. You can find our complete partners directory here.

For Microsoft Office 365 backup, RG system provides a solution hosted on OVHcloud datacentre.

For Cybercriminality incidences, SI Vital solution maintains access to your vital, uninterrupted data and applications, as well as a secure, professional communications platform. A business continuity solution co-constructed with OVHcloud.

Different Types of Storage For Your Backup

Whether you are using an Enterprise Backup Solution or a Specialised Backup mechanism, you can store the backups on dedicated servers (Bare Metal storage), dedicated storage (NAS/HA, Enterprise File Storage), or the current global preferred choice for backup: Object Storage.

All OVHcloud storage solutions : https://www.ovhcloud.com/en/storage-solutions/

And because a picture is worth a thousand words (and that’s about how many words you’ve read so far in this article):

Object Storage & Cold Archive

Object Storage is particularly well-adapted to backup because:

• data growth is not limited by the underlying hardware
• it’s cost-effective
• it’s pseudo disconnected or fully disconnected in some cases
• it’s application/Operating System agnostic
• it’s friendly to static data
• it works with tapes.

Our Object Storage options are:

• Standard Object Storage: ideal for general backups.
• Performance Object Storage: ideal for critical and large backups as its high performance reduces backup and restore time.
• Cold Archive: ideal for meeting the legal requirement for data conservation and disconnected backup for safety.

Block Storage

Block Storage is still a very attractive option for storing backups because of its predictable performance and safety inherent to direct access to storage and RAID. It is the favoured media for on-premises infrastructure as storage arrays are widely available and distributed across datacentres. This distribution and the potential replication options provided by the storage arrays allow you to keep your data safe without causing you headaches. One caveat to mention is that Block Storage it is mostly reserved for server backup since end users don’t have easy access to centralised Block Storage.

File Storage

If you want to protect your users’ shares/export, File Storage is very convenient and access to the data is not bound to physical connections as is often the case for Block Storage. As long as you have access rights and network connection, using File Storage for backup is easy. Most File Storage also provides snapshots, and even though it can’t be considered a backup solution, it does provide a fast recovery mechanism. Advanced File Storage solutions provide replication and High Availability mechanisms.

Expert & Partner Ecosystem

And if you feel intimidated, our Professional Services, Solution Architect and partners can help you make an educated choice and a solid migration. But what if your data is already in the cloud? How is it protected and how can it be?

Well, the devil is in the detail, and very often, protecting your data is your responsibility, not your provider’s. So never ever assume that because your data is in the cloud, it’s automagically protected in the case of an incident.
What we do at OVHcloud is provide access to snapshots for some of our services. But there’s no Service-Level Agreement associated with these snapshots and they may not respect the 3-2-1 rule, hence are not backups.

Conclusion

Let’s finish by talking about the ideal global backup service approach for you, encompassing software and storage. The main differentiator is going to be: how much control do you want over your backup? Once you have an inventory of the data you need to backup, the first step is to check compatibility with existing or future Enterprise Backup Solutions. Most of the time, you’ll find several solutions that are able to support your needs and protect a vast majority of your data, even if they’re both on-premise and in the cloud. Having all your data in the same place is of course easier, but it rarely happens.

Then you need to verify which of the Software Solutions you’re considering are suitable for your backup strategy. And this is the perfect time to step back and evaluate. Have you missed anything? Does everything follow industry standards? And finally, who can help you find the best compromise between safety and cost. Ideally, we’ve answered all these questions above, so let’s have a look at what we can offer here:

It is also available on our managed Bare Metal “Essentials” offer.

Our offer is to install and manage for you the SW and HW components. All you have to do is chose which VM’s to back up and let us do the rest. Well you still have to make sure that your backups are valid and test them regularly, but you knew that 😉

3 levels of services are available : Standard, Advanced and Premium.

These levels define different options and features

The service level chosen applies to to entire VMware Datacentre on which it is active and as such, on all the VM’s in the datacentre.

Currently, the features and options are as below :

Changing service level is possible after 15 days have elapsed on the current offer. Retention rule still applies until it expired (if you chose a new service with a shorter retention time).

Architecture

Let’s see in more details how does Veeam works and what is the system architecture.

When the Veeam backup option is enabled in the OVHcloud manager, a « backupserver » VM is automatically created by OVHcloud on your PCC host.

Creating this VM requires the usage of 1 Microsoft Windows license, taken from your Windows Datacenter licenses pack. If you haven’t subscribed to this option, a single Windows Datacenter license will be added to your next bill.

This VM is only accessible by the OVHcloud team and the SQL Db required is hosted on OVHcloud infrastructure. It only consumes the minimum CPU and memory required.

The same way, the VM backups are also stored outside of your PCC, on datastores dedicated to your backups, leaving your PCC storage unencumbered by backups.

With the standard service level, backups are stored in the same physical datacentre/location.

With the advanced and premium service levels, backups are replicated automatically on a distant location. (RGPD compliant)

All backups are encrypted by the Veeam « backup server » and the key stored in a PCI-DSS compliant database.

Each « backup server » and storage space for backup is personal to each customer.

Customer subscribing to premium service level will have 1 « backup server » on 1 host and an additional « backup proxy » VM on each other host in their PCC (each using a Microsoft Windows license).

Customers with a Standard or Advanced service level can request the deployment of « backup,proxy »on their hosts using the API :

GET /dedicatedCloud/{serviceName}/datacenter/{datacenterId}/backup/canOptimizeProxies

Long story short, this is how it looks like:

Adding « backup proxy » VM can be required if the number of VM to backup exceeds 15 on a given host or if the time to backup the VM exceed the daily backup window.

Backup jobs are programmed and executed automatically without human intervention.

• 3pm : VM inventory and assignment to « backup server » and « backup proxy »,
• 10pm : start incremental backups,
• 01am : start full backups,
• Between 8am and 9am : email report sent to Admin PCC NIC email (Premium service level allows for 1 more email to be configured).

In case of error during the backup jobs, a support ticket is automatically opened for investigation and resolution.

Note: a successful backup job is NOT a valid backup nor an immutable backup.

Test your backup regularly.

Our SLA’s for Veeam Managed Backup are

GTI, Goal Time for Intervention: Maximum time OVHcloud will take to intervene on an incident

GTR, Goal Time for Recovery: Maximum time OVHcloud will take to recover from the incident reported automatically by the system or by the Client 

SLA does not apply on the backup content nor the time it takes for the backup job to run.

This is why it is important to consider the service level chosen not to exceed the backup window by using “proxys”

Day to day

A plugin allows for backup selection to be managed directly using your Vsphere interface for each VM. Well, either it’s selected for backup according to your chosen service level, or it’s not selected. It is very simple.

Or you can also use the API

Don’t forget : the entire VM is backed up, so the entire VM will be restored.

That’s all for today, stay tuned for more post like this !
