There are a dozen or more cloud services that offer safe and secure online file storage space to consumers. Dropbox is probably the best-known such service although there are many others as well. Most of these file storage spaces even offer some amount of free storage space as a "free trial," hoping the customer will purchase even more space. Dropbox offers two gigabytes of free space while several others offer as much as five gigabytes. A few online file storage services offer even more space than that. Copy.com now offers 15 gigabytes of free storage space with an incentive to obtain even more space at no charge.
Copy.com is a division of Barracuda Networks, Inc., a well-known and respected provider of firewalls, spam filters, storage appliances, and more, normally used in corporate data centers. The new Copy.com service is aimed at consumers and corporations alike.
Copy.com provides desktop programs for Macintosh, Windows, and Linux. It also provides apps for Apple iOS and Android mobile devices. On the desktop computer, a new folder is created called "Copy." Anything you place into that folder is automatically copied to Copy.com's servers. You can also retrieve anything from those servers at any time in the future, if you wish to do so. On the handheld iPhone, iPad, and Android mobile devices, the Copy.com app shows what is available on the servers but doesn't actually retrieve a file until you tell the app to do so. In effect, any of your files store in Copy.com are available on demand wherever you are as long as you have an Internet connection.
Files are also easy to share with friends, family, and co-workers. Right-click on anything in your Copy folder to copy a web link to it. Send that link to your friend or family member by email. The recipient can click on the link and then will be able to view and/or download the file(s) you specified and only those files. Any other files you have saved in Copy.com remain invisible to everyone but you. You can also share entire folders which will keep your files in sync with someone else as if you both are working on the same computer.
At Copy.com you can browse, share, and upload files into your Copy folder from any computer. You can also see past versions of files and, in the case of shared folders, who has been editing them. This is a great feature if you accidentally delete a file or if a person who is allowed to share your folder deletes a file or even the entire folder. Copy.com can retrieve older copies of files as they existed before the files were deleted and then restore them at any time. Not all cloud-based file services can do that.
I installed Copy.com's software onto my desktop computer and found that it is a snap to use. I can simply drag any file or group of files to the Copy folder and then everything I selected gets copied to Copy.com. I can later retrieve any or all of the files to my desktop computer, laptop computer, or mobile devices.
However, there is no automatic copying of files. Some of Copy.com's competitors will search your local hard drive every day or maybe every hour and will then automatically send the newly-discovered file(s) to the cloud storage service. In contrast, Copy.com doesn't do anything automatically; you have to manually drag any files you wish to save to the Copy folder. If you have two or more computers, or if you are sharing files with someone else, Copy.com does not automatically copy those files to the additional computer(s). All copying must be done manually by clicking-and-dragging files or folders to the other computer(s). Some users will consider that to be an advantage while others think it is a disadvantage. Your choice.
Anyone can obtain 15 gigabytes of file space on Copy.com simply by signing up for the service. However, Copy.com users can earn an additional 5 gigabytes of additional free storage by recommending the service to others. If someone clicks on a referral link that you send, you obtain an additional 5 gigabytes of free space to your account and, best of all, the other person also obtains an additional 5 gigabytes of space. There is no limit on the total capacity anyone can earn.
If that isn't enough storage space for you, paid plans on Copy.com start at $9.99USD/month or $99USD/year for up to 250 gigabytes of storage space.
Since I am a user of Copy.com, I will invite you to click on my referral link of https://copy.com?r=NZC6tk. If you click on https://copy.com?r=NZC6tk and then sign up for the service, I receive an extra 5 gigabytes of free space in my account and you receive an extra 5 gigabytes in your account as well. However, whether you click on my referral link or not, I still think Copy.com is a great free service. Use my link or not, as you prefer.
