Comparison · Storage & Backup

Cloud backup and online storage for photos, projects and your computer compared

An additional off-site copy can protect your photos and project files from loss through burglary, fire or a failed computer. Separate backups and sufficiently long version retention also help against accidental deletion and ransomware. This comparison covers selected cloud backup and online storage services for freelancers and creative professionals. The order is not a ranking. We compare provider information on data location, data processing agreements, encryption, versions, trash, NAS support and pricing models. The selection is a starting point that can be expanded; it does not claim to cover the entire market. Sources and retrieval dates are documented. The assessment is based solely on the linked sources.

Features explained

Backup, sync, versioning, zero-knowledge: many terms sound similar but mean different things. Here are the most important ones in brief, so you can read the details in the table correctly.

B Backup
Backs up computers or folders automatically and restores them after data loss.
S Sync
Keeps folders identical across devices – not a replacement for a backup.
Sh Sharing
Shares files and galleries via link, with password and expiry.

How we compare

  1. Where the information comes from

    All information is based on the providers' own pages: pricing and product pages, help articles, privacy policies and contract documents. Every detail has a source with a retrieval date. TutKit did not use the services itself for this overview; statements such as "suits …" are clearly worded as assessments.

  2. Status and prices

    The information reflects the retrieval date of each source. Prices and plans change frequently; the current information on the provider's website always applies. The order of the entries is not a ranking.

The editorial team sets the order. In descending weight, it is based on: suitability for the audience’s typical use, features as compared here, pricing model (such as a free version, one-off purchase or subscription), and data protection and server location.

Research and drafts are partly AI-assisted; every statement has been checked editorially against its source and is the responsibility of Stefan Petri.

How we are funded

These comparisons are funded by commissions from affiliate links (marked *). TutKit also sells its own courses on some programs; they are marked “TutKit’s own offer” and are not part of the selection. There are no paid placements on these pages.

Buying guide

Backup or sync – what do you need?

A sync service keeps a folder identical across several devices. If you delete a file on your laptop, it also disappears from the cloud. A backup, on the other hand, keeps copies and lets you restore older states. Many online storage services offer both, some only one of them. So check whether a service includes automatic computer backup or whether you need a separate program for that.

Data location and data processing agreement

If you store client data – such as portraits, contracts or project documents with names – you are the controller under the GDPR. You then need a data processing agreement with the provider (DPA under Art. 28 GDPR). Also check where the data is actually stored. Company headquarters and storage location are two different things; with some services you choose the region when you create your account.

Versions and trash

Versions protect you against overwriting and ransomware, the trash against accidental deletion. What matters is how far back both go. If you only notice a mistake after weeks, a short retention period won't help.

Encryption

Almost every service encrypts data in transit and at rest. The difference lies in who holds the key. With end-to-end encryption (often called "zero-knowledge"), the provider cannot read your files. The trade-off: if you lose your password or key, your data usually cannot be recovered.

NAS and external drives

If your archive lives on a NAS, you need a service the NAS can reach directly – for example via SFTP, WebDAV, rsync or a dedicated app for Synology and QNAP. Pure desktop programs often don't back up network drives.

Storage space and pricing model

Plan with your actual data volume and allow for growth: RAW files and video projects quickly fill several terabytes. Compare whether a plan charges by storage, by device or by user, whether you pay monthly, yearly or once, and which minimum term applies. You'll find current prices directly on each provider's website.

The 3-2-1 rule

A proven approach: three copies of your data, on two different storage media, one of them off-site. A cloud backup covers the off-site copy – it does not replace your local backup.

Terms

Backup

A safety copy that remains separate from the original. A good backup also keeps older states so you can go back after mistakes or attacks.

Sync (synchronisation)

Keeps folders identical across several devices. Changes and deletions are applied everywhere – which is why sync alone does not replace a backup.

Versioning

The service keeps earlier versions of a file. This lets you restore a file that was overwritten or encrypted by malware.

Trash

Deleted files first end up here and can be restored for a certain period. After that, they are gone for good.

End-to-end encryption (zero-knowledge)

Data is encrypted on your device before it is uploaded. Only you hold the key; the provider cannot read the content.

Data processing agreement (DPA)

Agreement under Art. 28 GDPR. It governs how a service provider processes personal data on your behalf.

NAS

Network attached storage: a network drive in your office or at home, for example from Synology or QNAP. For a cloud backup it needs a way out, for example SFTP, WebDAV, rsync or a dedicated app.

SFTP, WebDAV, rsync

Transfer methods that programs and NAS systems use to write files to storage. Which ones a service offers determines which software you can use for your backup.

Conclusion

The right service depends on what you want to back up or share. Hetzner Storage Box is an inexpensive technical option for a NAS and your own backup software. HiDrive offers German data centres and a data processing agreement; important features may cost extra. pCloud combines online storage, sharing and different payment terms, while encrypted folders and contract questions need separate consideration. Tresorit focuses on encrypted collaboration. Backblaze automatically backs up user data on one Windows or Mac computer, but does not create a complete system image. IDrive offers backup for multiple devices and NAS options. For Internxt, pay particular attention to file versioning restrictions and conflicting data location statements. MEGA pricing and contract information still require another check before approval.

These ten services cover different use cases; they do not form a ranking. Choose according to your needs, check current terms and perform a trial restore after setup.

Frequently asked questions

Is a sync service like a cloud folder already a backup?

Not automatically. A sync service also carries deletions and overwrites over to all devices. It only becomes a backup if it keeps older versions and deleted files long enough. How long that is for each service is shown in the table.

Do I need a data processing agreement as a freelancer?

As soon as you store personal data of your clients in the cloud – for example photos of people, addresses or contracts – the provider processes this data on your behalf. Art. 28 GDPR then requires a data processing agreement. Whether and how a service offers one is shown in the table under "DPA". If in doubt, clarify the details with your data protection advisor.

What does zero-knowledge encryption mean for me?

Your files are encrypted on your device, and only you hold the key. The provider cannot read the content. In return, it usually cannot help you if you lose your password or key. So keep both separately and safely, for example in a password manager.

How do I back up my NAS to the cloud?

Usually via your NAS's backup app, which can target a destination via SFTP, WebDAV, rsync or S3. Some services offer dedicated apps for Synology or QNAP. Desktop backup programs on your computer, by contrast, often don't include network drives. Which methods a service supports is listed under "External drives and NAS".

Why are there no prices here?

Prices and promotions change frequently. So that you don't see outdated amounts, the comparison names the pricing model – for example subscription, one-time purchase or billing per device – and refers you to the current prices on the provider's website.
