Head to Head

Pricing has a starter option that’s free and that never expires. This is for 5 GB of storage. Then, there’s the Pro Business option which is $5 per month for 1 TB of storage. If you upgrade to 2 TB storage per month, this goes to $8 per month for Pro Personal.

You can use DropBox for free as much as you want within the initial amount they give you, which is usually around 2 GB. This is definitely less than other reviewers have noted.The Dropbox Business option is $12.50 per user per month, though you get 5 users to start. You also get 2 TB of storage space with features for collaboration. It’s worth noting that definitely offers you the same storage amount for considerably less money. This is further complicated by the type of service you’re looking for, however. You can get 1 TB at $10 per month or so if you don’t need the extra business options for collaboration. This is still more expensive than though.

SpiderOak has a free option, but it’s limited, unlike with DropBox or You can do 2 GB for 60 days. Then, it’s $7 per month for 30GB or $12 per month for 1 TB. This is definitely on the more expensive side. It could be worth if you want to gain that extra level of customization, however.

Box gives you a huge amount of file storage for backups for free at 10 GB. The problem is that you only have a 250 MB file upload limit. So, if you have a lot of small files on your computer that need to be backed up, this is the option for you. The paid version is going to be $10 per month for 100 GB of storage with the file upload cap extended to 5 GB.

Tresorit has $10.42 per month for the Premium service, though this is only when it’s priced yearly. This include 100 GB of storage, making it pricier than other options. You also get 5 devices to use. The “solo” plan is $24 per month for 1 TB and 10 devices.

Overall, Box gives you the most for free, and has some of the cheapest options at $5 per month. SpiderOak and Tresorit care definitely closer to the high-end level of things in terms of their costs that go up towards $24 per month for the same storage you get for half elsewhere, but they do provide more for the money.

Features has the 30-day file recovery option as well as getting file versions when you have a subscription. There are mobile options for iPhone and Android, and the “Zero knowledge” privacy approach is important to many people as well. This means that your password isn’t stored at They don’t have access to it. Even the metadata is encrypted and the type that only you cab access. There’s actually a pledge they make on the site to never access your data, even beyond the fact that they can’t. They also pledge to never sell any of your personal data or pretend they own it. The site is Canadian and in compliance with HIPAA as well as Canadian versions.

DropBox lets you try out the service for 30 days at paid levels just like, so they are comparable in that way. Dropbox Business costs more than, but you get 120 days of file recovery instead of just 30 like you do with get Smart Sync with the business version of dropbox, as well as the ability to control permissions on a granular basis. There’s also a two-factor authentification option through the business account as well.

SpiderOak has features that lend themselves well to customization. For example, you can add as many users as you want to your account, and you can specify exactly when backups happen. This could be every 5 minutes, or it could be exactly at 2 PM on Tuesday and Friday, for example. You can even specify backups according to size and type.

Box has features that lend themselves best to free users, especially those without big files. They have the largest free option of any service with 10 GB, though they also have the 250 MB cap. Box is like DropBox in terms of features in that it’s easy to set up and sync files, and there’s a lot of options when it comes to compatibility with third-party apps and services.

Tersorit has a 14-day trial, which is less than others.They also have a security-focused suite of features, although these are better suited for businesses and users looking more for higher end stuff than what offers.

Overall, it’s worth noting some comparisons between data backup features such as the file recovery metric where has 30 and Dropbox has 120. Other worthwhile comparisons are how Box has a built-in music player in addition to its file storing service, but lacks this feature. Another area of comparison is in free trials. SpiderOak has 60, but no free option. The paid options for DropBox and Sync are 30 days, and the one for Tresorit is 14 days, so it really runs the gamut, and the best will depend on what you want.

Reviewers also liked the 5 GB of extra space if you do referrals and other bonuses. Downsides include that the bigger plans are often overpriced, that it’s difficult to automatically use files since they often have no in-house editing options and that many sharing abilities only work through the Web.

High reviews for DropBox come from PCMAG at 4 out of 5 and Cloud Awards at 4.2 out of 5. The main benefits include how DropBox can integrate with a huge number of third party apps, estimated at over 100,000. People do complain about the lack of support features as well as certain security concerns like its Google sign in, for example.

SpiderOak is also a top level cloud backup service with strong reviews like a 3.5 out of 5 from PcMag, a 4 out of 5 from Cloudwards and a 3.7 out of 5 from Backup Review. Some of the negative aspects reviewers point out is that the backup feature is a bit hard to navigate and setup.

Box definitely has its supporters with PC Mag reviewing it at 4.5 out of 5 with a pronouncement of “excellent.” They praise how it’s easy to use and works well with other apps. Reviewers also say that it has many features and that you get a huge amount of free storage. Negatives include that some collaboration tools are absent as opposed to what you get elsewhere.

Tresorit appears to lack reviews when compared to other options, and many of them aren’t as positive. Backup Review gives them a 3.1 with over 15 reviews total. Review Technica gives them an 8.4 out of 10, and a few other assorted reviews are way up and down the spectrum in terms of positivity. Positives pointed out are the two-step verification option even if you go free, and up to 90 days of history for the paid option. Complaints involve how it’s difficult to use the controls since they aren’t especially intuitive, that the service is comparatively expensive, and that upload speeds can be slow.

Overall, both SpiderOak and stress that they give out encryption keys making it so that only the user has access to their data.SpiderOak appears to allow more users per account than DropBox business accounts, for example, since SpiderOak allows infinite users and DropBox only allows 5. Another big difference in reviews includes that Dropbox is praised for collaboration tools whereas Box has some, but not as many. They do have file-syncing and contact importing, however.
