There are several options available to avoid such issues. One option is to use a private cloud instead of a public cloud (there are as well providers that offer private cloud storage). Another option is to ingest data in encrypted format where the key is hold within your on premise infrastructure. Access is often by use of cloud storage gateways that are on premise. Such gateways have options not only to encrypt and compress the data prior of transfer but as well mirror the storage across multiple cloud storage providers and remove the risk of a single providers shutdown. Gateways offer as well the option to cache data on a most recently used algorithm on premise. Along with data analytics data is cached and fetched on a most valuable form instead of recently used only form.
Google also recently introduced Google Photos, an online photo locker, where you can organize photos into albums. Google Photos is built into Drive in a separate tab, but you're really better off going straight to googlephotos.com to see and organize photos. However, you don't need to download the Google Photos app on your phone or tablet to back pictures you take there. The Google Drive app can take care of that.
Thank you so very much, Branko! I hadn’t come across Sync at all until I read your review here. I’ve signed with them, and they are terrific! Much faster servers than Dropbox have been for me here in Australia. I was desperate to get a large audio file to a client. After days, Dropbox was still dropping out. Sync had it loaded in just over 1/2 hour! Amazing! I greatly appreciate the time you’ve put into this article.
SendSpace is a file-sharing utility that's been around since 2005. It includes a desktop tool — for Windows, Mac, and Linux systems — and mobile apps for iPhone and Android phones. SendSpace's claim to fame is that you can share gargantuan files with others securely, and it functions more like a conduit for your files (you're sending them, after all) than a cloud storage space for information you want to share with others. This ability to send mega-size files has worked well for me. I've used it to send gigabytes of book files to colleagues in other countries, and the service has been easy to use and reasonably prompt for those times when I need to deliver a file right away.
First up is OneDrive, Microsoft's storage option. Those who use Windows 8 and 10 have OneDrive built into their operating system, where it shows up in the file explorer next to all of the files on your computer's hard drive. However, anyone can use it on the Web, by downloading a desktop app for Mac and earlier versions of Windows, or the OneDrive Android, iOS, Windows Phone and Xbox apps.
Users with specific records-keeping requirements, such as public agencies that must retain electronic records according to statute, may encounter complications with using cloud computing and storage. For instance, the U.S. Department of Defense designated the Defense Information Systems Agency (DISA) to maintain a list of records management products that meet all of the records retention, personally identifiable information (PII), and security (Information Assurance; IA) requirements[23]
Cloud storage isn't just for storing files; it's also a great platform for real-time collaboration. Google Drive offers 15 GB of free cloud storage as well as access to Google's Web-based productivity suite. The business version of G Suite comes with unlimited storage as well as additional business features for Gmail, Google Hangouts and Calendars. Users can save, edit and invite others to work on Docs, Sheets and Slides right on Google Drive itself. The business version starts at $10 per month per user. drive.google.com

Backblaze is a simple to use and affordable cloud storage platform for general use. Its B2 Cloud Storage can be used for storage, file sharing, hosting or large-scale backup. This software is optimized for Mac systems and integrates with OS to allow you to seamlessly backup and restore your system in the event of data loss or a complete system loss. You can return your computers to the state they were in 30 days prior, which is useful for deterring ransomware or other malware.
Dropbox is still a good choice thanks to the sheer number of platforms it supports. Tresorit and pCloud are two services that deserve a lot of attention. Security is a very important consideration these days and both of these  manage to provide encryption in a way that doesn’t interrupt a normal workflow and is easy to manage - especially in the paid versions. 

Disable auto-uploads. If you are concerned about sensitive info or pics, turn off the auto-upload function on services such as Dropbox or Google Photos. These services automatically save a backup version of your documents in the cloud but don't distinguish between everyday photos and files and the ones you really don't want getting into the wrong hands.
One of the reasons that Tresorit is so secure comes down to the way files are encrypted. With a local client installed on either your Windows or mac OS machine your data is encrypted locally, then sent to the Tresorit servers where it remains encrypted. You retain the decryption keys (not that you’ll ever see them) and not even the staff at Tresorit can access your files, thanks to their Zero-Knowledge policy.

Saves time. Business owners and the average person can save a great deal of time, thanks to sharing files via the cloud. Now, there’s no need to save the files to a device, transport that device and insert that device into a computer in order to access the files. With just a few clicks of a button, files can instantly be shared. Talk about a huge time saver.
If you don’t have a pressing reason to choose another service, then it’s hard to go wrong with OneDrive. Furthermore, if you’ve bought into Microsoft’s Windows 10 ecosystem, then OneDrive is the best solution for you. It touts a decent amount of free space (5GB), along with inexpensive upgrades and the ability to get 1TB of storage with an Office 365 subscription. Microsoft’s cross-platform strategy means that mobile support is very strong, including Windows phones, Android, iPhone, and iPad.
With high-profile data security and privacy breaches escalating over the past couple of years, SpiderOak aims to give businesses some peace of mind. The company offers a 100 percent private cloud storage, online backup, sync and sharing service that utilizes a "zero-knowledge" privacy environment, which means only the user can see the stored data – not even the SpiderOak staff or the government.
You could also just pass files back and forth via a service like MASV, if you’re sending archives of drafts and finished work to one another. It’s less useful if each client just wants to have a folder they can reference that’s full of everything you’ve worked on together: old and new projects, invoices, artwork, documents, spreadsheets, et cetera. Similarly, there’s Hightail—also worth considering, with the same kind of limitations.
CrashPlan combines online storage with complete backup services. The service backs up changed information as often as every minute and continues to watch for changes to data in real time. After the first backup completes, CrashPlan checks for data that is already backed up and ignores it, making subsequent backups much smaller because they contain only new or changed information.
Dropbox was among the first services to offer seamless upload and storage via its client software (though Box beat Dropbox to market by two years). The service is enhanced with an impressive ecosystem of third-party apps that integrate with Dropbox, including Salesforce, DocuSign, Jira Software, Office 365 and Slack. And though Dropbox has primarily focused on consumers and SMBs, its recent IPO filing document states that the company has ambitions for the enterprise market (and already has some large business customers). Dropbox gets high marks for being easy to use, and its growing collaboration features, such as the new Showcase interface for sharing files with partners and clients, continue to improve. Its free plan only offers 2GB of storage, however – a pittance compared to Google Drive’s 15GB.
Like the other services, you can use your files via Box's website and even create basic text documents. To make it shine, you'll need the Box Sync and Edit apps for Windows or Mac OS X. It also comes with Android, iOS, and Windows Phone apps that will enable you to view, upload and share files. Box is also now integrated directly with Google's Chrome OS or Chromebooks users.
Upgrading to the Personal Pro plan will cost you £80/US$10 per month, earning you 100GB of storage and a file size limit of 5GB, or you could switch to the Starter business plan for £4/US$5 per month, which also offers 100GB, a slightly lower 2GB file size, but works with teams of 3-10 people, supports document encryption, granular permissions and stores previous versions of any file.
You can also post photos directly from OneDrive to Facebook, LinkedIn, Twitter, and other social-networking sites, which is a nice, time-saving touch. The service also offers built-in remote access capabilities. From the OneDrive.com website, you can get access to any PC associated with your account that has the OneDrive client installed, even files not already uploaded to OneDrive.
Resilio Sync (formerly BitTorrent Sync) is the best cloud storage solution for everyone that wants to do their own cloud storage. This app allows you to use your desktop, laptop, NAS, tablet, or even your own home-built server as a destination for your phone syncing. It operates exactly like Dropbox, Google Drive, etc, except you’ll be using your own machine to store everything. It’s an excellent option for those who are security conscious but still need cloud storage also. The only downside is that you’ll need to keep your receiving machine on all the time so that the syncing can be done. The best part is that the app is completely free and you’ll have as much storage as your receiving device can hold.
If you don’t know how much storage you need, and chances are high you’re going to be needing more and more you should try one of the services which offer unlimited storage. You can find more about them on our best unlimited cloud storage providers list. Make sure to check our feature lists so you’re aware of any file size restrictions or limitations.
