The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.

NIce article although the author doesnt seem to know that there are two measures of a disks performance
1) Throughput - measured in MBytes/sec
2) Bandwidth - Measured in IOPS
These two measures are mutually linked ie 100MB/s can either be 1*IOPS*100MB, or 100*IOPS*1MB
The figures seem to also show a lot of cache effects, or have dubious provenance, otherwise how does a USB connected drive achieve 2289.5 IOPS (how do you get .5 of an IOPS anyhow)

Hi Gerald,
I do understand there are several things to take into consideration when measuring the performance of any hard drive, however going into depth in so far as eliminating cache effects would go beyond the scope of what this article is attempting to achieve. You may have also noticed that I didn't mention or talk about the effect FSB speeds can have on a hard drive's performance either?
As I mentioned at the start of the article;
Indeed. How do you get a .5 of an IOPS ?
Or even a .7 or .8
How about you tell us? :-)
Thanks for your feedback. Always great to hear back from ones readers.
Best regards,
Andrew

The reason you might want to skip the QD32 tests is that they're not particularly useful for real life scenarios and just take additional time to run. QD stands for "Queue Depth" so the software also measures "separate thread" transfer speeds. Information not of much use for our purposes. I only include the results that I got below for the sake of completeness.I think the general flow of the article from that point forward clearly shows it is targeting beginners to hard disk performance measuring and not representing any type of advanced hard drive performance analysis.

Absolutely true! Backup is mandatory these days. I would recommend multiple backups (different hosts). The most common threat these days is indeed Ransomware and that's because it is very different from other types of viruses. Learn more about it and what you need to do to keep your data safe.

AWS Glacier is Amazons cheapest storage option and is their answer to a ‘Cold’ storage service. Customers primarily use this service for archival purposes and storage of infrastructure backups. Its unlimited storage potential and low storage cost makes it a popular storage choice.
What can be sometimes overlooked are the retrieval costs of your data, depending on how much you retrieve and over what time period can make a huge difference. This article will cover these costs and help you understand the considerations of data retrieval. Its important to note that AWS prices are exclusive of any GST or VAT chargeable (more information on these fees can be found here.)
Retrieval Costs
When you find yourself in a situation where you need to retrieve data from Glacier you need to understand some of the costs to ensure you can complete it in the most cost effective way.
You will probably be aware that AWS boasts a retrieval rate of $0.01 per GB; however this is not as simple to calculate as it seems.
It’s important to note that you can retrieve up to 5% of your total AWS Glacier for free each month which is monitored on a pro rata basis daily. Therefore if for example you have 15TB of data stored on Glacier you could retrieve 25GB a day for free (15TB * 5% (0.05) / 30(days) = 25GB). 25GB would be your daily free allowance.
Any data retrieved over this amount per day will be chargeable based upon other …

In this technological trend, we all know the importance of our data. Instead of storing it in a physical device, why not to keep it over the cloud and let it follow you wherever you go. Being in a digital world, Cloud Backup is one such thing every internet consumer should acquire.

Hard drive sizes are not given in binary, so I didn't go that route.
I also didn't bother to take TCP connection overhead into account either
We're looking for ballpark figures here.
You clearly live someplace with good, cheap network connections -- but you wrote an article for a global audience.
Our shop is in a new area of one of the fast growing regions of our nation.
To get symmetric DSL of 10 Mbps, I'd have to pay $5500 to get fiber to the door and $1350 / month for the service.
A connection like yours 20 Mbps (~120 Mbps download) is simply not available unless you'd pay the astronomical costs of a partial T3 frame relay.
You've missed my point. It doesn't matter what the Cloud has to offer if you have to sip through a very expensive straw -- and the numbers you posted about your differentials are not making sense for your argument
75 MB change every day : 30 minutes to do the daily upload
To get the whole 130 GB up there in the first place
130 GB = 130,000 MB
150 MB per hour
868 hours
36 days.
My point is simple.
If you are going to talk about Cloud-based DR scenarios, the VERY FIRST POINT of discussion has to be effective networking speeds and costs, otherwise, you are wasting your own time and everyone else's
And with your own numbers, if your download is 6x your upload, you are looking at 6 days to pull your data back down. What business can afford that?
I also backed everything up to two separate outboard hard drives which are my backup backups running EMC backup software.
Good idea. Because in the breach, the usefulness of Cloud-based DR is very limited.
And your article fails to discuss such pitfalls.

Your article does not give the impression that you intend the cloud as a tertiary contingency -- which is what it really should be.

Sorry to hear you're not happy with Carbonite's 30 day retention policy. Carbonite was designed as a backup rather than a journaling or archiving service so we wanted to make sure that when you did need to do a restore from your backup that you wouldn't get a lot of data that you had deleted on purpose. Our research indicated that data that wasn't restored within 30 days was usually deleted on purpose so we set up our retention that way.
If you'd like our Carbonite Server Backup offers configurable retention and you can set it to never remove any deleted files: http://www.carbonite.com/en/cloud-backup/business-solutions/server-plans/
If you wanted to learn more about why we set up Carbonite that way or wanted to give more feedback feel free to leave a note back, or Private Message me here on the site. Thanks!

Great article! We actually have a lot of people come to Carbonite to back up their NAS device either locally using our Server product or backing up the cloud using our Server and workstation tools.
