All sorts of data disasters happen, even when you rely on cloud services. Downloaded ransomware locks local files that sync to the cloud. An errant update erases essential data. Poor password management leads to lost control of an email account. A misconfigured command wipes out a variety of virtual machines. An employee eager to save storage space selects a set of rarely accessed folders and files, deletes them and empties the trash: No one notices for more than a month, at which point it is too late to recover the files.

Businesses that care about data need a solid backup solution. Before you select a solution, you’ll want to identify every place organizational data gets stored, since different systems back up data from end-user devices (e.g., phones, tablets, laptops or desktops), centralized storage (e.g., servers and network attached storage devices) and cloud services (e.g., Microsoft 365, Google Workspace, Salesforce). You also may want to estimate the total storage space required for backups. The following paragraphs focus on cloud backup of cloud data.

What is cloud backup?

A cloud backup is a copy of data that you access over the internet. As of 2022, most backup services offer cloud-based options that consist of software installed on a device that automatically copies new or changed data to remote servers over the internet. Before sending your data, the system typically encrypts the data (to help secure it) and also often compresses it (to reduce transfer time). Cloud-based backup may play an important role in data recovery in the event of a disaster, theft or malware issue.

Importantly, backup of data is not the same as sync. When you use a service such as Google Drive, for example, Google’s systems keep files in sync. Delete a file and it moves into the trash. Wait for more than 30 days and the file is gone after Google’s systems automatically empty the trash. That’s sync. A backup service, in contrast, will typically retain data for a much longer period of time. Should you need to recover a file deleted within, say, the past year (or more), a backup service allows you to do so.

What are cloud backup services?

A cloud backup service provides storage of data for a fee. Pricing is often based on the quantity of storage, the number of accounts, volume of data transferred or other services desired.

The cloud backup services covered below are all ones that offer cloud-to-cloud backup. Unlike a device-to-cloud service, which copies data from a laptop, onsite server or network attached storage device, cloud-to-cloud backup automatically backs up data from one or more software-as-a-service (SaaS) vendors. For this type of backup to be possible, the SaaS vendor needs to support access to system data in a secure manner. Sometimes, less sophisticated SaaS vendors lack this capability, so make sure to verify that vendors allow cloud-to-cloud backup when you select SaaS solutions.

Cloud backup services sometimes specialize. For example, a few vendors focus solely on backup of Microsoft 365 or Google Workspace data. These services ensure that an administrator can easily retrieve copies of email, files, calendar events and other items from the organization’s chosen cloud-based collaboration platform. While both Microsoft and Google maintain highly redundant and reliable systems, neither preserves versioned backup data of deleted data for more than a brief period of time.

Cloud-to-cloud backup vendors provide different levels of encryption control, data storage and retention options, and may also be governed by different laws and contractual agreements. Some vendors allow you, as the customer, to retain control of encryption security keys. Sole access to the encryption key ensures you are the only person with the key to decrypt the data. The downside, though, is that if you lose the key, you also lose access to the encrypted data. Where possible, assuming that you are ready to accept the responsibility, prefer a vendor that allows you sole control of encryption keys.

SEE: Cloud data storage policy (TechRepublic Premium)

Data storage retention controls may allow you to select not only what data is retained, but also for how long, as well as exactly where it is stored. These settings matter because data security and privacy laws differ in various countries and governments. If your backup contains sensitive data, you may not wish to have it stored in a place where it might be accessed by governmental officials. Additionally, if your organization must comply with HIPAA provisions, you should seek a backup provider willing to sign a business associate agreement. Many vendors blog about healthcare, but not every vendor that does so is willing to sign a business associate agreement.

Choose at least one backup solution

No matter how many devices or data storage sources an organization has, a responsible IT leader will make sure that all essential organizational data is backed up. Sometimes, this means a mix of solutions: one vendor for cloud-to-cloud data backup and another for device backup. Other times, it may make sense to consolidate backup with an enterprise-focused vendor that offers a diverse suite of solutions. A reliable backup solution helps ensure that you can recover data whenever necessary.

Regardless of which vendor you select, be aware that SaaS backup services focused solely on serving the backup needs of a business are rare. Services with a cloud-to-cloud SaaS backup offering typically expand to offer related features (e.g., management, migration, compliance or training) or choose to focus on a specific customer segment (e.g., IT managed service providers or resellers, rather than an end-user business customer). These changes often result in a wider range of products and services available, but may diminish a vendor’s distinctive focus on backup. Be ready to review your selected backup system as vendor focus and strengths evolve.
