As a photographer, what's the best cloud storage solution for backing up huge RAW photo files?

If you're a photographer dealing with hundreds of GB or multiple TB of RAW files, I’d separate backup from cloud storage/sync. They solve different problems.

My pick: Backblaze for backup

Backblaze is particularly well suited to a large RAW library because its personal computer backup is unlimited, including connected external drives, and it doesn't impose file-size limits. Current pricing is $99/year for Personal Backup.Backblaze+1

That's a much better fit for, say, 8 TB of RAWs than paying for 8 TB of conventional cloud-storage space.

How I'd set up a professional photo workflow

• Working catalog/photos: Fast local SSD/RAID/NAS.
• Primary backup: Backblaze continuously backs up the computer and directly attached photo drives.Backblaze+1
• Second local copy: Another physical drive/NAS, preferably kept separately from the workstation.
• Cloud storage for selected/current projects: Use something like Dropbox or Google Drive if you need convenient syncing, sharing, or access from multiple machines.

This follows the basic 3-2-1 backup principle: multiple copies, on different media, with at least one off-site.

When I'd choose something else

Dropbox currently offers 2 TB for Plus and 3 TB for Professional, with larger team plans available. It also supports online-only files, which can be useful when you don't want your entire RAW collection consuming local SSD space.Dropbox+1

Google One currently offers plans up through 5 TB, with storage shared across Google Photos, Drive and Gmail.Google One

One important distinction: I wouldn't use Dropbox/Google Drive alone as the backup of your master RAW archive. They're primarily storage/sync services. For a photographer, I'd want an actual automated backup system in addition to them.

If you tell me roughly how much data you have (e.g. 2 TB, 10 TB, 30 TB), whether you're on Mac or Windows, and whether your RAWs live on internal drives, external drives, or a NAS, I can give you a concrete setup and estimated monthly/yearly cost.

When dealing with massive RAW photo files (which easily bloat a library to multiple terabytes), "the best" solution depends entirely on whether you need a true set-and-forget disaster-recovery backup or an active workflow/client-delivery cloud sync.

Because RAW files break traditional file structures with their sheer size, photographers generally split their strategies into three distinct categories:

• True "Set-and-Forget" Backup (Best for pure disaster recovery): Services like Backblaze Personal Backup are hard to beat. For a flat monthly fee, it offers unlimited storage for a single computer and attached external hard drives. It runs continuously in the background, meaning every time you dump a 100GB card of RAWs onto your drive, it quietly uploads to the cloud. The catch: It’s an archival backup, not a file-sync or sharing tool. If you delete a file locally, it eventually drops off the cloud.brault.app
• Workflow & Portfolio Storage (Best for active projects and client proofing): SmugMug is legendary for working professionals because their higher-tier plans offer unlimited full-res storage alongside RAW file support and gorgeous client-facing delivery galleries. If you want something tightly integrated into editing, Adobe Creative Cloud / Lightroom lets you sync smart previews or full RAWs straight through your editing ecosystem, though paying for multi-terabyte tiers gets expensive fast.pcmag.com+1
• Sync & Multi-Device Access (Best for working across laptops/desktops): pCloud or IDrive are fantastic alternatives. pCloud natively handles RAW previews and even offers a Lightroom plugin, while IDrive gives you multi-device backup under one account and a hybrid local/cloud setup. If your initial data dump is too massive for your internet connection, IDrive will physically ship you a hard drive (IDrive Express) to seed your initial backup.

Most working professionals lean toward a hybrid strategy : an unlimited background archiver like Backblaze for absolute safety, paired with a local NAS array (like a Synology) or a portfolio platform like SmugMug for active client work.

To help narrow down the ideal choice for your setup, tell me:

• How many terabytes is your current photo library?
• Do you primarily need disaster recovery , or do you need to share/edit from the cloud on multiple devices?
• Are you already tied into an ecosystem like Adobe Lightroom?

When dealing with massive RAW photo libraries (where a single shoot can easily hit 100 GB to 500 GB), the "best" cloud solution depends entirely on whether you want a set-and-forget disaster recovery backup or an active multi-device syncing workspace.

The top solutions are categorized below by how they handle heavy RAW workflows:

• Backblaze — Best for Set-and-Forget Unlimited Backup
  • Key Feature: Truly unlimited storage for a flat annual fee.
  • The RAW Advantage: You don't have to pick and choose which folders to back up. It runs quietly in the background, handling internal and attached external hard drives filled with hundreds of thousands of raw files without choking or asking for more money as your library scales to tens of terabytes.
  • The Catch: It is a backup service, not a cloud syncing drive. You can't easily browse or edit your RAWs on your phone from a coffee shop; it's designed to get your data back if your office or studio hard drives physically die.
• Adobe Creative Cloud — Best for Workflow & Multi-Device Editing
  • Key Feature: Deep, native integration with Lightroom.
  • The RAW Advantage: If you use the cloud-centric version of Lightroom, your original RAW files are uploaded straight to Adobe's ecosystem, letting you punch out edits on an iPad or laptop while traveling and have those changes instantly reflect on your master workstation.
  • The Catch: It gets expensive fast once you exceed basic tiers (like 1 TB), and it's built for active editing/syncing rather than a deep archival safety net for all your historical multi-terabyte unculled shoots.
• Dropbox — Best for Speed and Client Collaboration
  • Key Feature: Lightning-fast block-level syncing and robust file recovery/version history.
  • The RAW Advantage: Handles massive single-file uploads smoothly, allows RAW preview thumbnails on the web/mobile app, and makes sharing large selections or final deliverables with clients painless.
  • The Catch: Pricing scales steeply per terabyte compared to dedicated backup options, and it functions as a live sync folder rather than an automated drive-mirroring backup.
• pCloud — Best Long-Term Value (Lifetime Plans)
  • Key Feature: One-time purchase "lifetime" storage tiers rather than an endless subscription cycle.
  • The RAW Advantage: Fully supports RAW file previews, has high transfer speeds, and even offers an optional client-side zero-knowledge encryption add-on for sensitive commercial shoots.
  • The Catch: The upfront cost for multi-terabyte lifetime plans is steep, though it pays for itself if you keep the service for more than 3 years.

The Golden Rule for RAW Storage

No matter which cloud host you pick, remember that cloud storage is not a complete backup . Relying solely on a live sync folder like Dropbox or Google Drive leaves you vulnerable to accidental deletions syncing instantly to the cloud. Most working professionals use a 3-2-1 strategy : local working drive, a local physical backup (like a RAID or external NAS), and an offsite automated mirror like Backblaze.

To help narrow down the ideal choice, tell me:

• How many terabytes is your current photo library?
• Do you prefer a flat subscription/annual fee , or do you want to manage local external drives yourself?
• Are you looking to edit on the go from mobile devices, or just archive safely?

Choosing the "best" cloud solution for massive RAW photo files (25 MB to 100+ MB per frame) depends entirely on what you mean by backup : do you want a set-it-and-forget-it disaster recovery net , or an active, browsable working library?brault.app+1

The top solutions separate cleanly into three distinct categories based on your actual workflow needs:

1. Best for Pure, Hands-Off Disaster Recovery (Unlimited Archive)

If you have multi-terabyte local arrays or external hard drives and just need an off-site safety net so a house fire or dying RAID doesn't wipe you out, dedicated backup rules the day.brault.app+1

• • Backblaze Personal Backup: The absolute gold standard for sheer value. For a flat annual fee (around $99/year), it offers truly unlimited storage for your computer and any attached external hard drives. It quietly hums in the background.
  • The Catch: It is an archive/backup, not active cloud storage. You can't comfortably browse thumbnails on your phone or a remote laptop. If you lose everything, you restore via download or have them ship you a physical hard drive.
• • IDrive: A great alternative if you want a mix of cloud storage and backup. It lets you back up external drives and multiple devices under one account, with multi-terabyte plans that are competitively priced.youtube.com+2

2. Best for Active Multi-Device Workflows (Cloud Sync & Browsing)

If you want to edit on the go, jump between a desktop and a laptop/iPad, and need your files accessible from anywhere with native RAW rendering.

• • Adobe Creative Cloud (Lightroom Ecosystem): If you already pay for Adobe, the cloud-centric Lightroom workflow syncs your full-res originals (or smart previews depending on settings) straight to Adobe's data centers. It provides seamless cross-device editing—shoot on location, edit on an iPad in bed.
  • The Catch: It gets very expensive once you scale past 1 TB to 2 TB of heavy RAW archives, and it isn't built to mirror external scratch disks like a true disaster recovery tool.
• • pCloud: Highly praised for photographers because it natively supports RAW file thumbnail generation and previews in the browser. It functions like a traditional folder structure, allows file sharing with clients, and crucially offers lifetime plans if you hate recurring monthly subscriptions. It also features client-side encryption add-ons for privacy.

3. Best for Client Delivery & Presentation

• • SmugMug: Built specifically for professional photographers. While it doesn't store raw files directly for deep archival backup (it focuses on high-res JPEGs/displays), it is unmatched for building gorgeous, secure client proofing galleries and automated print fulfillment.pcmag.com+2

The Ultimate Pro Recommendation

Most working professionals don't rely on just one cloud tool; they use a hybrid 3-2-1 strategy:

1. Keep a local working copy on a fast local SSD/RAID.
2. Maintain a local physical backup (another external desktop drive).
3. Run Backblaze in the background for continuous, unlimited off-site RAW archiving.

To help narrow down the exact tier or provider you need, tell me:

• Roughly how many terabytes of RAW files do you currently have?
• Do you primarily use external hard drives or internal storage?
• Are you looking for disaster recovery , or do you want to edit directly from the cloud?

For a photographer with hundreds of GBs or multiple TBs of RAW files, I’d separate “cloud backup” from “cloud photo library.” You generally want cheap object storage + automatic backup software, rather than paying a consumer cloud service to sync everything.

My top pick: Backblaze B2

backblaze.com is probably the best overall choice for a working photographer.

• $6.95/TB/month currently.
• Your RAW files stay in an always-available cloud tier.
• No minimum file size or minimum storage-duration fees.
• Free egress up to 3× your average monthly stored data; additional egress is $0.01/GB.
• Supports S3-compatible workflows and integrates with numerous backup applications.Backblaze+1
• Has security features including Object Lock, encryption and MFA, which are useful against accidental deletion/ransomware.Backblaze

So, for example, 10 TB of RAWs ≈ $69.50/month before any applicable taxes/extra usage.

The other excellent option: Wasabi

wasabi.com is extremely attractive if you expect to retrieve your photos frequently.

It's $7.99/TB/month and doesn't charge for egress or API requests under its applicable policies.Wasabi+1

The catch is important: Wasabi has a 90-day minimum storage-duration policy and a 1 TB minimum commitment under its Pay-Go terms.Wasabi

So I'd choose:

What I would actually do

For a professional photo workflow, I'd use a 3-2-1 backup strategy:

Working files → Local backup → Cloud backup

For example:

• Primary: your computer/NAS/RAID containing current Lightroom/Capture One catalog and RAWs.
• Local backup: a second large HDD/NAS, preferably in a different physical location.
• Off-site: Backblaze B2 containing the actual RAW files and important catalogs.
• Optional: keep JPEG exports/previews in Dropbox/Google Drive if you need easy client sharing.

The key point is that RAID isn't a backup and neither is simply syncing your Lightroom folder to another drive. You want an independent copy that can survive theft, hardware failure, accidental deletion, fire, or ransomware.

What about Dropbox/Google Drive?

They're great for access and collaboration, but I'd generally avoid using them as the primary long-term archive for 5–20+ TB of RAW photography. For example, Dropbox Professional currently provides 3 TB for $16.58/month, which gets expensive quickly as your archive grows.Dropbox

Bottom line: If you tell me roughly how many TB of RAWs you have now (and how much you add per month) and whether you use Mac/Windows + Lightroom Classic/Capture One + a NAS or external drives, I can recommend the cheapest setup and estimate your actual monthly/yearly cost.

When dealing with massive RAW photo libraries (where a single wedding or landscape shoot can easily hit 50GB–100GB+), the "best" solution depends entirely on your primary goal: pure set-and-forget disaster recovery , or an active, browsable cloud library.brault.app+1

A breakdown of the top solutions categorized by how they handle heavy RAW files highlights these distinct approaches:

1. Best for Set-and-Forget Unlimited Archiving: Backblaze Personal Backup

If you want an absolute safety net for your entire local drive and attached external hard drives without calculating gigabytes or paying per terabyte, Backblaze Personal Backup is unmatched [12.1].brault.app+1

• The Good: Truly unlimited storage for a flat monthly fee (around $9/month), and it automatically backs up RAW files as they land on your computer or plugged-in drives [12.1].brault.app+1
• The Catch: It is a backup service, not a cloud sync/drive [12.1]. You cannot easily log into a web browser on a different device to casually browse, organize, or edit individual RAWs on the go. If a local file is deleted from your computer for 30 days, it disappears from the cloud backup too.
• Best for: Photographers who practice the 3-2-1 backup rule locally and want an inexpensive, hands-off cloud safety net against fire, theft, or total drive failure [12.1].brault.app+1

2. Best Value for Tiered Storage & Multi-Device Control: IDrive

If you don't need infinite storage, but want high-capacity tiers that let you back up multiple computers, NAS devices, and external drives into one account.youtube.com+1

• The Good: Offers massive capacities (like 5TB or 10TB) at a fraction of the cost of Dropbox or Google Drive. It supports block-level incremental backups, meaning after the initial massive RAW upload, it only uploads changed bits.pcmag.com+1
• The Catch: Like Backblaze, it's built for backup rather than active media management—don't expect slick RAW image previews or cloud editing inside the dashboard.brault.app+1
• Best for: Photographers managing multi-terabyte archives across a couple of different studio machines.youtube.com+1

3. Best for Active Workflows & RAW Previews: pCloud

If you need to access, preview, and share your RAW files from anywhere without clogging up your local laptop's internal SSD.brault.app+1

• The Good: Unlike Google Drive or Dropbox (which often show generic icons for specialized camera RAW formats like .CR3 or .ARW), pCloud natively generates thumbnails and previews for most major RAW formats right in the browser or app. They also offer unique lifetime storage plans , meaning you pay once and avoid recurring subscription fatigue.brault.app+1
• The Catch: Gets expensive upfront if you opt for the multi-terabyte lifetime tiers.
• Best for: Photographers who want a hybrid of active cloud storage and easy client-sharing capabilities without losing the visual ability to see their RAW files.brault.app+1

4. Best Ecosystem Integration: Adobe Creative Cloud

If you are already living inside Lightroom and want a seamless workflow.brault.app+1

• The Good: Lightroom ecosystem natively syncs your original RAW files straight to Adobe's cloud. You can shoot on location, let it sync, and pull up the exact same RAW file on your tablet or desktop to edit with zero friction.
• The Catch: Storage tiers get very expensive once you start scaling past 1TB or 2TB. It is also an ecosystem lock-in—if you stop paying for Adobe, managing the transition of your cloud library can be painful.
• Best for: Mobile or studio shooters who deeply value cross-device editing and want Adobe to handle the cloud heavy lifting.brault.app+1

Pro-Tip Recommendation

Most working professionals don't rely on just one cloud layer. A robust setup usually looks like this:

1. Local: Physical RAID/NAS array or local external drives for fast, day-to-day editing.
2. Cold/Deep Backup: Backblaze Personal Backup running silently in the background to catch every single RAW file for disaster recovery [12.1].
3. Delivery/Active Sharing: A selective workspace like SmugMug or pCloud for client galleries and active portfolio storage.brault.app+1

To help narrow down the ideal pick, tell me:

• How many terabytes of RAW files do you currently have?
• Do you need active web browsing/client delivery from the cloud, or just a disaster recovery backup?
• Are you already tied into an ecosystem like Adobe Lightroom or Apple Photos?
