Powered by Windows Storage Server 2008 R2 Essentials

Make the Most of Your Capacity
Go for a NAS that grows with your needs and lets you do more with fewer gigabytes. No need to back up the same files, such as email attachments or system files, for several employees. These redundant data are a waste of space. Thanks to its PC backup data deduplication feature, the LaCie 5big will only back up a single instance of redundant data. This lets you not only optimize your storage space, but also increase backup speed. Smaller backups equal faster backups and more available storage space.

The Industry-Standard Operating System
Go with a professional backup system for your small business. Go with what you know. The LaCie 5big is powered by the industry-standard Windows Storage Server 2008 R2 Essentials. Get up and running in a flash with a straightforward setup process and a familiar Windows environment.

A Cost-Effective, Professional Solution for
Small Business

It's no small feat to find a professional backup solution for a small office on a budget. Capable of backing up 25 PCs, the LaCie 5big is the ideal choice for your business. Opt for the single-drive version and add additional drives* as you need more capacity. Reduce your investment and ensure a long-term solution.

No-Compromise Hardware

Efficient Cooling for a Long-Lasting Product
The cooling system can have a dramatic impact on the long-term reliability of your server. The LaCie 5big's dual cooling is the best protection against overheating throughout its lifespan. First, its solid aluminum casing diverts and dissipates heat effectively. Second, its whisper-quiet, thermo-regulated Noctua® fan automatically adapts its spinning speed to the internal temperature. As a result, the fan cools the components, which is vital for a better long-term investment.

Non-Stop Normal Operation
Powerful software demands high-performance hardware and resources. With the 5big, LaCie made no compromises. The dual-core 1.6GHz Intel 64-bit Atom processor and 2GB of RAM ensures maximum simultaneous data access by employees. You also have enough resources to efficiently execute daily backups for all the 25 PCs in your company. This muscular hardware configuration gets the job done. No need to settle for less.

Boost Network Speed with Link Aggregation
Go fast with a Gigabit Ethernet port. Go even faster with two Gigabit Ethernet ports. Increase the speed of your network with link aggregation of the two Ethernet ports. This lets you improve information sharing and backup speeds throughout the company.

Complete Data Protection. Simplified.

Protection Against any Calamity, Including Human Error
Your business data are sensitive, and protecting them is paramount. The LaCie 5big secures your files at every point, taking human error out of the equation. It automates backups of your office's computers, from individual files – even open ones – to the entire system. Simply install Connector – the backup client software – on your office's computers, then the LaCie 5big does the rest. No further configuration required. What's more, support for incremental backups means that only changed or new files are backed up. Combine this with PC backup data deduplication, and you're truly getting the most out of your capacity.


Restore any File or Even an Entire System
With Windows Storage Server 2008 R2 Essentials, it's easy to restore a file or even a complete workstation operating system. Thanks to robust versioning management, you can prevent data loss in the case that an employee accidentally deletes an important file. You can even browse through all saved files and select the one you want to restore. What's more, if a workstation's hard drive fails, you can restore the entire system. A simple wizard helps you to create a reinstallation DVD or USB key. This lets you restore the damaged system to the exact state captured in the latest backup. Complete system restoration. Hassle-free.

No Data Loss. No Downtime.
The LaCie 5big supports secured RAID 1 and RAID 5 modes for automatic, hardware-level 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. Whatever the challenge, zero data loss, zero work interruption.


Distance Your Data From Threats
For an additional level of data protection, back up your data to an offsite location. Prevent local technical problems or acts of God from causing downtime with NAS-to-DAS backups. Simply set up automatic backups to a connected DAS, which you can then take away to a safe place. Or, eliminate the need for human intervention and automate this task with NAS-to-NAS backups. This lets you schedule frequent backups to another NAS located in another room or building. Going even further, the 5big Office integrates Wuala Business, LaCie's Secure Cloud Storage for SMB. So now you can back up your critical data to the cloud.

Sharing Done Right

Easy Configuration. Low Maintenance.

Painless Integration
Integration into your infrastructure is as simple as ABC. No network knowledge is required to start. Simply connect the LaCie 5big to your network, run the utilities DVD, and configure automatic backups. It takes just a few clicks. The browser-based Dashboard gives you quick access to key tasks. Control RAID management, user management, or backup status in the blink of an eye.

Easy User and Group Import and Management
Dramatically simplify how you manage users and groups with Active Directory and Windows domain support. It only takes 30 seconds to join the LaCie 5big to an existing domain. Users, groups, and permissions can then be quickly imported and synced from your existing Windows infrastructure. Once set up, you will never need to do it again. Zero repetitive tasks.

Low Maintenance
Hard drives need to be replaced when they are full. With the LaCie 5big, you can slide in a new one without needing to hit the power button first. You can install higher capacity drives to add storage, or replace a failed drive, all with no downtime.

Help When You Need It
Your LaCie 5big is protected by a three-year limited warranty. It includes comprehensive, complimentary web-based resources, expert in-house technical support, and worldwide repair/replacement coverage. Advance Care Option can also be purchased. For details, see
