There’s a question that comes up every time someone loses files: why didn’t you have a backup? The answer is usually the same: they had compared backup options at some point, but never decided. Something curious happens with backup tools. Everyone knows they should use them, few compare them with any real criteria, and almost no one tests restoration until it’s too late.
This article isn’t about choosing the «best» backup tool, because no such thing exists universally. It’s about comparing the popular options of 2026 with a practical approach: what each one solves, where it fails, and who it’s meant for. If you’re looking for a table with stars and an absolute winner, this isn’t what you need.
First: define what you’re backing up
Comparing tools without knowing what you’re going to protect is like buying moving boxes before checking how many cubic meters you have. Before opening any comparison of popular options, it’s worth answering three questions:
- How much data is it? 20 GB of family photos is not the same as 4 TB of videos from a small YouTube channel.
- How often does it change? An office laptop changes daily; a family archive of old discs almost never does.
- How long can you go without that data? This is where the concept of RTO (recovery time) and RPO (how much information you can lose) comes in.
In my case, for years I used an external drive permanently connected to the computer. One day the drive stopped mounting and I discovered two things: that the copy was the only one and that I had never tested restoring. That experience changed the way I compare backup options: now the first thing I look at isn’t the price or the space, but whether I can recover a specific file in less than five minutes.
The popular options, one by one
1. External drive with synchronization software
It’s still the most common option for home users and small businesses. The comparison here isn’t between drive brands, but between approaches: synchronization (mirroring) versus versioning.
What works well: it’s fast, it doesn’t depend on the connection, and the cost per terabyte is low. Tools like the utilities included in Windows or third-party solutions let you schedule automatic copies.
Where it fails: if you synchronize instead of versioning, an accidental deletion is replicated in seconds. And if the drive is always connected, ransomware or a power surge can affect both the original and the copy at the same time.
Who it’s not for: anyone who needs access from multiple devices in different locations. An external drive doesn’t solve that without complications.
2. Cloud backup services
Here the comparison gets more interesting because there are two families that are constantly confused: folder synchronization services (like Google Drive, Dropbox, or OneDrive) and true backup services with versioning and system images.
The first are convenient, but they aren’t a backup in the strict sense. If you delete a file locally, it’s deleted in the cloud after a grace period. The second are designed to recover complete states of the machine, including the operating system and applications.
Specific limitation: the initial upload speed. If you have 2 TB of data and a home fiber connection with limited upload, the first copy can take days. I’ve seen this in video projects: the cloud is excellent for day-to-day use, but the first upload requires planning.
This doesn’t work for: machines with unstable connections or with data that changes constantly in high volume. There, a hybrid strategy is better.
3. Home or small-office NAS
A well-configured NAS is probably the most balanced option for anyone with several devices who wants control over their data. It allows scheduled copies, snapshots and, with the right configuration, remote copying to another NAS or to the cloud.
Important warning: a NAS is not a backup in itself. It’s network storage. If you only have the data on the NAS and it fails, you’ve lost everything. The 3-2-1 rule (three copies, two media, one off-site) is still the most useful comparison criterion there is.
Concrete example: in a small office I advised, they had a NAS with two mirrored drives and believed they were covered. Both drives were from the same batch and model. When one failed, the other showed bad sectors during the rebuild. The mirror wasn’t a copy: it was a redundancy of the same risk.
4. Tape copies or cold storage for archiving
Less popular in homes, but relevant in companies with retention obligations. Comparing this with the cloud is common and almost always unfair: they don’t compete, they cover different needs. Tape is still alive for long-term archives because of cost and durability, but it requires hardware, software, and procedures.
Not recommended for: home users. The maintenance curve doesn’t pay off.
Comparison table by real criterion
Instead of an «overall score» table, I propose comparing by criteria that matter in day-to-day use. Each popular option stands out in something and falls short in something else.
| Criterion | External drive | Sync cloud | Cloud backup | NAS |
|---|---|---|---|---|
| Initial ease | High | Very high | Medium | Low |
| Ransomware protection | Low if connected | Low | Medium-high | Medium with snapshots |
| Cost per TB | Low | Medium | Medium-high | Medium long-term |
| Remote access | No | Yes | Yes | Yes, with configuration |
| Restoration test | Simple | Simple | Varies by service | Requires procedure |
The restoration column is the one almost no one looks at when comparing and the one that should weigh the most. A backup that has never been restored isn’t a backup: it’s a hope.
How to compare without falling for the marketing
Backup services tend to highlight space and price figures, but rarely mention retention policies, version limits, or what happens if you cancel the subscription. When comparing popular options, it’s worth reviewing:
- Retention policy: how many versions does it keep and for how long?
- Export: can you download your data if you leave? In what format?
- Encryption: do you control the keys or does the provider?
- Restoration support: recovering a single file isn’t the same as restoring a complete system.
My practical conclusion, without an absolute winner
After trying several combinations, the comparison that has served me best isn’t between products, but between strategies. For a home user with photos and documents, an external drive for local copying plus a cloud service with versioning covers most scenarios without complications. For a professional with critical data, a NAS with snapshots and external replication (to another NAS or to the cloud) offers a level of control that’s hard to achieve with a single tool.
What I don’t recommend is relying on a single popular option for convenience. Convenience is precisely what makes backup get forgotten until it’s needed. And when it’s needed, the question is no longer which tool was the best, but which one was configured and tested.
None of these options guarantees that you won’t lose data. The only thing that really reduces risk is combining media, testing restorations periodically, and documenting the procedure. The useful comparison, in the end, is the one that forces you to do a recovery test before trusting it.
