Choosing cloud storage for 3CX Backups

Since explaining how to backup 3CX to cloud storage, it would be good to cover cloud storage and what is best for 3CX backups – both in cost and usability.

Cloud Storage ranges from top-tiered storage providers such as Amazon, Azure and Google through to the smaller, providers such as Wasabi, Backblaze and everything in between (OneDrive, GoogleDrive, Box).

We aim to help you choose the right provider for you. Previously we have covered cloud storage rate-limiting – in this; we will primarily look at cost and features that prove valuable for a backup service. 

Amazon Web Services S3

Amazon Web Services (AWS) are the big guys. They have been around the longest in the cloud game and have the experience and infrastructure to back it up.

It offers scalability, availability, security and performance. It is dIt offers scalability, availability, security and performance. It is designed for 11 9’s of durability and meets most, if not all, compliance standards from HIPAA to PCI-DSS compliance. From a backup point of view, it offers incredible access control, data replication, data protection and S3 versioning. All of this ensures you have your precious data, where and when you need it.

S3 Standard Pricing

The pricing is relatively standard across the scope of cloud storage, and the difference truly is what you get for your price. The above benefits aren’t available as readily or easily across all storage providers, hence why AWS S3 is often most people’s number one choice.

Azure Blob Storage

Microsoft is a trusted and well-proven enterprise partner. Although Microsoft was slightly delayed in the cloud game (compared to Amazon), it has caught up something chronic and is cheaper than AWS S3. Often the debate that will never be won is AWS vs Azure, but really it depends on your preference.

Azure offers; consistency where an object change is verified everywhere for data integrity, easy to use geo-redundancy, multiple storage types – block, page and append blobs, and object mutability where you can have the flexibility to perform edits in place.

Azure Blob offers Hot, Cool, Archive or Premium storage straight off the bat. This gives you the flexibility to choose the storage type that fits your backup needs. Much like AWS, Azure offers redundancy and file versioning, but it does pride itself more on its geo-redundancy which can go up to 16 9’s of durability.

Unless you are looking to use Azure Managed Disk option, Azure is far cheaper than AWS S3.

Google Cloud Storage

Google Cloud Storage, depending on your region, has the highest price per GB out of the three big guys. Google claims to have high performing object storage that has been designed for secure and durable storage. One thing they speak about is their environmental friendliness, and their goal is to reduce data storage carbon emissions to zero.

A great feature is their object lifecycle management where data will transition to a lower-cost storage class after it has met specified criteria. This would be key for saving costs with your 3CX backups. However, it would be critical to check that 3CX backups can handle the movement of files.

Much like the above it supports object versioning, retention, object holds to prevent deletion and encryption.


Wasabi Cloud Storage was covered in How good is Wasabi cloud storage? To prevent too much repetition, one thing that Wasabi does well is it simplifies the entire cloud offering landscape. One price and no hidden fees. Although this may not work for all, as some may prefer using one vendor for all, or Wasabi may not work for you due to its limited global reach. However, from a “standard” cloud storage point of view, Wasabi is the best bang for your money which allows you to invest financially into other areas of your infrastructure, people and processes.


Backblaze B2 has excellent infrastructure for cloud backups; it allows for unlimited free uploads and free 1GB of downloads per day. Each account gets 10GB free storage and only charges 5 cents per GB, which is a lot cheaper than any of the above.

Backblaze has been going since 2007 and has a decade of experience and a wide range of customers from small to big using their products daily.

Dropbox, Box, Google Drive and OneDrive

Your Enterprise friends. These guys are easy to integrate with as there is a high chance you are already using them internally, or if not, depending on your chosen suite (Google Drive or OneDrive) you may get a substantial amount of storage for free that you can use.

Dropbox is the most versatile and well rounded. It integrates well via its API and has impressive speeds. It’s own features from replication to restoring deleted files is great for backups and much like the others can be a versatile collaboration tool enabling files to be easily shared and worked on.

Google Drive and OneDrive are both parts of a total solution offering, which more often than not, your organization more than likely uses one of the two. Due to this, it then entitles you to use this space for backups with the right integration. The downside, especially with Google Drive is its rate-limiting that can impact your uploads and cause connections to become unstable or drop off.
