Any Place. Any User. Single Interface.

Introducing the True Hybrid Cloud
With LaCie products* running NAS OS 3, you get a true hybrid cloud: integrated network-attached and secure cloud storage. LaCie is alone in the market having its own cloud storage product, Wuala. As a result, LaCie is uniquely positioned to deliver a seamless hybrid cloud solution.
Easy Setup,
Seamless Integration

Simply connect the product and install the Wuala client, and instantly you have 100GB of free trial Wuala Business cloud storage**. Wuala file system integration means both network and cloud storage mounts on your computer just like an external hard drive. So you can easily drag and drop files onto the NAS or the cloud. It also lets you access and work on files wherever you go – and even edit files with productivity software – without needing to download them.

Complete Compatibility
Not only does Wuala work on Windows®, Mac®, and Linux, but also on mobile devices (iOS™ and Android™). Just install the Wuala app on your smart phone or tablet to gain access to any file stored on your LaCie 2big or 5big NAS Pro. Make your data as mobile as your employees are (but constantly available).

Centralized and Intuitive Administration

Flexible Tools for Complete Control
Because your time is money, LaCie NAS OS 3 hybrid cloud takes usability to new heights. Create and manage users and groups directly from the simple-to-use Wuala client, as well as keep tabs on storage usage. Manage folder syncs and backup from a single, centralized location.
Untethered Administration
Out of the office but want to create a new user, grant someone permissions to a folder, or verify that the NAS-to-NAS backup has completed? No problem. Get it all done from a hotel room via your laptop or mobile device’s browser.

Collaborate without Missing a Beat

Work Smarter, Work Together
In addition to file system integration, LaCie NAS OS 3 hybrid cloud gives work groups winning tools for collaboration. It lets you automatically sync files between the cloud and one or many of your company's computers, or between computers and the NAS. This ensures that everyone's looking at the most current versions. Sync makes sure that an employee in sales, for example, won't use an outdated price list, or be unable to pull up marketing collateral during a sales pitch. Since your Wuala Business users have access to a shared pool of storage, it's easy to keep everyone on the same page.

Better External File Sharing
What's more, instead of using FTP or email to share files with external clients, simply provide them access to LaCie NAS’s browser-based file explorer. They can download files directly without needing to be granted access to your company's network. No file size restrictions means you can share large files easier than ever.

Formidable Data Security. Simplified.

All-Points Security for Constant
Data Availability

Files need to be constantly available or productivity suffers. That's why LaCie designed NAS OS 3 to protect digital assets throughout the network. It starts with Wuala backup, which can be configured to automatically protect files stored on networked workstations. Even if a computer crashes or an employee accidentally deletes an important file, restoration is easy and fast. You can even create automatic backups of your NAS onto another NAS (local or remote▴) or connected external hard drive.
Sophisticated RAID Protection
Files stored on the NAS are protected with disk-failure proof, hardware-level RAID protection. If a single disk fails, you can replace it without turning off your appliance. Just swap in a new one without losing a single byte of data. The SimplyRAID feature*** can even control RAID for you, making advanced data security simple enough for novices. Using SimplyRAID, you also get improved available storage compared to traditional RAID solutions when using disks of different sizes.
Easy Maintenance and Troubleshooting
Prevent downtime by keeping a close eye on your hardware. NAS OS 3 now features hardware monitoring that alerts you in real-time of potential issues with the fan, CPU, and RAM. It also features SMART hard disk diagnostics. Stay on top of your data security with hardware status email alerts.
