Sauvegarde en tant que service (BaaS)

Backup as a service definition

Backup as a service (BaaS) solutions offercloud-based data backup etrecovery capabilitieswithout the presence of physical,on-premises hardware or appliances to host etrun the backup infrastructure. Unlike traditional data protection solutions which require self-managed backup software,along with tapes,disks,etphysical or cloudstorage,BaaS enables IT admins etprofessionals to offload backup application hosting etmanagement to a third-party cloud service provider.

Organizations simply connect to their BaaS solution to securely access,store,or recover data backup copies from a remote cloud location. This model helps reduces the upfront etoperating expenses associated with owning,installing,operating etmaintaining backup etrestore applications.

With cloud adoption,backup evolved from its traditional role as simple copying of data to a remote location into a more sophisticated data protection etbusiness continuity approach.

What is backup as a service?

BaaS is a SaaS-delivered solution that provides data protection etbusiness continuity capabilities. Copies of primary,application,or on-premises data are stored in the cloud etare maintained in a usable form that enables faster recovery following a disruptive event. Data copies are verified for integrity and,in most cases,kept in immutable,air-gapped locations which are decoupled etseparate from company networks. This isolation keeps backup copies out of the wrong hands etsafe from accidental etmalicious accidents. BaaS solutions can protect a range of workloads – with most vendors protecting SaaS or cloud application data. A more comprehensive BaaS solutionwill cover a range of workloads both on-premises etin the cloud. For protection of on-premises workloads,a resilient BaaS solution would enable making two copies of the data,one for faster onsite recovery etthe other for sending to a secure air gapped cloud storage location. Companies today are using the cloud for a safe backup repository to leverage its scalability,security,etcompliance capabilities.

What is backup as a service,ethow does it work?

As noted earlier,BaaS solutions seek to reduce management overhead,while protecting against data loss. BaaS solutions help companies prepare to quickly return the business to normal conditions whether facing accidental deletion,data corruption,or ransomware attack. Prudent planning calls for solutions which enable for fast recovery of data,etthe flexibility to rapidly restore backup copies whether kept onsite or in private/public cloud locations. Businesses need clear BaaS plans with details on the backup/restore processes,frequency ettypes of backup,testing etvalidating procedures,etprotocols for data restoration etbusiness continuity. During the entire lifecycle,special attention is needed to ensure robust security etadherence to regulatory requirements.

Types of backup managed by a backup as a service solution include:

• Full backup performs a complete copy of all data,or all content,on the devices designated as part of the backup process. This backup is performed at the start of implementing a backup policy.
• Incremental backup only copies the data that has changed since the last full backup job.
• A differential backup backs up all the data that has changed since the last full backup.

In addition to outlining backup frequencies,the backup policies etprocedures should also include therecovery point objective (RPO) metric,which defines how far back the data will be restored. The RPO value places demands on the systems involved requiring more resources for shorter RPOs.

A robust BaaS strategy can include:

• Clarity of procedures etschedules that outline the frequencies of backups etclarify the ownership etresponsibilities for each process.
• Choice of backup options to satisfy the needs of organizations in terms of the timing etfrequency of backups.
• Redundancy of backup copies to ensure fast recovery with nearby copy etair gap protected second copy for other occasions,including malicious attacks.
• Protection of data copies etdata by encrypting data in flight etat rest.
• Security with hardened,multi-layered controls to prevent unwarranted access etthe lateral movement or loss of data.

In addition,Backup as a Service can be purchased by a company as a SaaS-delivered solution for which they manage the day-to-day backup operations.

Alternately,a Managed Service Provider can offer backup as a service as a fully-managed,white glove offering that includes additional services like support,or backup job operations etmanagement.

Why is backup as a service important?

The amount of data created daily is staggering,etall of it must be stored etprotected against loss. By 2025,it is estimated that 463 exabytes of data will be created each day.¹ Users rightfully expect to have the data they need accessible etavailable around the clock. With a robust backup policy,businesses can back up etrestore their data etprotect it from potential loss.

In addition,because it does not require management etmaintenance of the backup infrastructure,a BaaS solution can significantly reduce management costs ettime spent,while reducing on-premises IT footprint.

Malicious disruptions. Data theft etbackup deletions by cybercriminals increased by400% since the start of the pandemic.² The cost of a data breach in the US increased 46% in 2020 compared to 2019,reaching an average cost of 8.64M. But not all attacks are external. The impact of data breaches extends beyond the economic costs ethas a long tail effect that extends for months after the disruptive event.

Unintended disruption. Unintended data loss is inevitable. From data corruption,to application failure,to accidental user or admin error,businesses of all sizes must properly prepare for outages etdata deletion events. Without a reliable data protection BaaS strategy in place,many businesses would suffer loss of vital data etextended disruptions etdisaster recovery times. In short,BaaS is your best option for keeping the engines of your business running etbrings them back to life faster in the event of an outage.

Benefits of backup as a service

Digital data etapplications are key drivers of business growth. Deploying a BaaS strategy is vital for protection against the potentially devastating impact of malicious data theft or negligent data loss.

Adopting etenforcing a backup policy can help enterprises in numerous ways:

• Cloud adoption. SaaS solutions revolve around simple subscriptions,predictable costs,etno large capital investments – making it an attractive etviable option for organizations today. Data protection is no different. BaaS data protection provides enterprise-grade protection with the same benefits etconsumption model as existing SaaS solutions,capable of helping companies deliver on cloud-first initiatives,shed tech debt without sacrificing security,etrapidly deploy etscale.
