This backup is typically used so that if your computers hard drive fails, you can install a new drive and simply restore it back to the way it was. It's not really intended to restore files individually.
The backup systems that the OP is talking about are cloud based and backup your computers "drives" over the internet to servers (i.e. big computers) owned by Carbonite and/or Backblaze. So instead of having an external drive sitting next to your computer that is subject to failure, theft, fire etc., you rely on a company's owned computers to keep your data safe.
The drawback to using cloud based backups is that 1. it costs money 2. it's very slow and depends on your internet connections speed, your modem speed, and the speed or bandwidth of the company's computers system that you are backing up to. 3. The cloud could be hacked or they could go out of business or they could corrupt your data. 4. restoring your files is VERY slow and sometimes very complicated.
Most of the time you can't simply use their cloud services to just search for a particular file and restore it. I'm not saying this about all of them, but some of them it's either difficult to do or impossible to do.
Restoring files via "Timemachine" is also cumbersome. You will have a hard time or impossible time finding one file and restoring it. This is because they don't write the backup "file for file". They use some other way of doing the backup that compresses the data.
Backing up to an external drive using simple file to file backups is fast and easy. If you accidentally delete a file from your computer, simply go to the external drive and the same exact file will be backed up in the same exact folder using the same structure as it was on your computer. Very simple and easy to access. But again, doing it this way could be troublesome if you have a fire or a theft of your equipment. So I suggest you purchase 2 external hard drives and make a copy of the first backup to the second one and then store the second one in a safe place. I store mine in a safe that is fire rated. Some choose to put them in a bank vault, their car, a relatives home etc.
Another way to keep data safe and not rely on the cloud is to use a RAID storage backup system like this one from Western Digital

If one hard drive fails it lets you know, then start automatically backing up to another. Hot swap the failed drive and it will automatically restore it via the other drive that hasn't failed. All done while you sleep and it's automatic. Kind of expensive though.
This reply is meant to be an overview and not be super accurate on how things work. I'm not an expert and have done some reading about his in the past. Some of my knowledge is from past experience working on friends Macs and my own PC's. I have not done any recent research on this subject so things may have changed a little since then. So please, those of you who read my reply, don't get all over my case if there are some discrepancies. I apologize if there are, and there probably will be.

Permit me, with all due respect, to correct a few things.
1) with all the major cloud services that I’ve used that include Amazon S3, Google and Microsoft, the file structure in the cloud looks exactly like your file structure that you upload, with the exception that the path is different. You can access/restore a single file, a folder or the entire file system exactly as you would on an external drive
2) the upload speed is basically a nonissue unless you’re using a dog slow connection, such as DSL. The initial “seeding” of the cloud and future updates of new or changed files can be scheduled to run at night when you’re asleep or as a background task, so no effect on you even if the initial seeding takes weeks. If you have a LOT of data and a VERY slow connection, many services will allow you to send them a drive with your data.
3) if the worst happens and you need to restore more than a few files, then you’ve had a disaster of some kind such that your backup is non functional - it’s a last resort scenario. Remember that if that happens, you have options. First, remember that you can restore to anywhere with an internet connection. Secondly, Gbit Ethernet is becoming ubiquitous in most major areas and 100-200 Mb/sec is often available unless you live in the country, and you can often upgrade your service for one month to do the download in an emergency. Finally, many services will send you a hard drive with your data (which you can return after downloading). Just for reference, assuming Gbit Ethernet actually transfers data at half the specified speed or 500 Mb/sec, that’s about 60MB/sec, 3600 MB (3.6 GB)/min and 216 GBytes/hour or 5 about hours to download 1 TB. In short, Gbit Ethernet’s spec is very close to the spec’d speed of a conventional HD.
4) finally, there has never been a case of a major cloud provider going belly up, and only one that I know of for a 2nd/3rd tier provider (Nirvanix), and in that case, users were given over a month’s notice to move their data. As far as data being hacked, consider that hackers aren’t interested in sorting through tens of thousands of your files for that one nugget of useful information. They want a nice clean database with SSNs or credit card information from a company such as Equifax. In every case that I’ve seen investigated when an individual got hacked, it was user failure - poor password management (including single authentication), sloppy computing practices, etc. - those are the real dangers to your data.
Keep in mind that 2/3 of all US companies keep some of their data in the cloud, and the rest are headed that direction. Your medical records, military records, credit card information, banking information and even highly secure information form the NSA and CIA are already in the cloud. Remember, it’s your disaster recovery copy, not your only backup, and there’s no way you can possibly devise and implement a system as safe on your own.
