It also supports Hybrid Backup Sync that consolidates backup, restoration and synchronization functions (using RTRR, rsync, FTP, CIFS/SMB) for easily transferring data to local, remote and cloud storage spaces as a comprehensive data storage and disaster recovery plan.
* Up to 256 snapshots per volume or LUN, and a maximum 1,024 snapshots per NAS. It is recommended to use block-based LUN snapshots.
Comprehensive security to protect your data
In open network environments, business data may be exposed in a potential hack. The TS-873U provides numerous security options, such as antivirus, encrypted access, IP blocking, 2-step verification, and more. IT administrators can also control the access rights of each user to different folders, preventing unauthorized access to important files. The TS-873U supports AES 256-bit encryption, preventing sensitive business data from unauthorized access and breach even if the hard drives or the entire system were stolen. Windows AD server, LDAP server, and built-in LDAP service are also supported.
Secure access with VPN & Proxy Server
The new QVPN app combines VPN Server and VPN Client functionality. Through QVPN, the TS-873U can be used as a VPN server with L2TP/ IPsec, OpenVPN, and PPTP support, allowing you to securely access data shared within the private local network. The TS-873U can also be used as a VPN Client to connect to other VPN servers or virtual private network through PPTP and OpenVPN for secure data transmission. VPN Client also allows your NAS to connect to multiple servers at the same time. You can connect your devices to your NAS and the VPN server at home to access data on the LAN; via VPN Client on your NAS you can connect to international VPN servers for accessing regionally-restricted services such as Netflix and Hulu in HD Station.
Fast data filing and searching to double your productivity
The TS-873U provides Qfiling and Qsirch for effortlessly organizing and searching for files, providing you with a highly-efficient data storage center. Qfiling automates file organization - simply determine filing conditions, set a schedule, and files will be organized and archived based on your settings. The Qsirch full-text search tool features quick file searching and supports thumbnail previews, content abstract, keyword hints, and more. Both apps provide huge productivity boosts that greatly reduce the time spent looking for files on the NAS, allowing you to focus on other tasks.
Centralized email and contact management for improved communication workflows
It can be hard to manage emails and contact information that are scattered across multiple computers, devices, and accounts - not to mention if important emails or contact information are lost or become inaccessible due to account closure or device malfunction/loss. QNAP QmailAgent and Qcontactz helps you centrally store and manage emails and contact information, making them accessible to all of your devices at any time - and with the powerful Qsirch search engine, you can easily find specific contacts and emails whenever needed.

What is NASBIT?
NASBIT© is a Licensed trademark of SimplyNAS. The acronym stands for Network Attached Storage Burn in Testing. This term is used to describe the process of testing new Network Attached Storage (NAS) hardware and firmware for faults before putting it to use in a live environment. This is done by running 'Stress testing' software for a stipulated period of time often 24 to 48 hours, but longer if needed.
When we receive an order for a NAS system pre-installed with disk drives it's prepared and configured with RAID followed by burn testing to ensure the entire system undergoes a thorough examination thus ensuring the server passes all tests to the highest standards set by us. Should the system hardware or any associated components fail at any point of the testing cycle the system is pulled and returned back as faulty our relevant vendor partner, the process seems simple but setting it up is far from easy.
Hard Disk Drives
All Hard disk drives are pre-tested prior to integration; the smallest of faults be it tolerable within industry standards are classified by us as faults, the hard drive is rejected and eliminated from the process and again returned back to source as a D.O.A. (dead on arrival). We continue to select drives from different batches, so as to eliminate any bad batches that may have been produced during manufacturing.
One integrated the drives are put through a vigorous routine that includes stress testing, including temperature tests and a host of read, writes to ensure the drive platters are stressed to the nth degree.
First, when the new server is turned on, we boot off of the network, and proceed to run the memory test that takes its sweet time, almost 10-12 hours dependent on manufacturer and model.
The appropriate RAID level is set and the system awaits completion of RAID synchronization. Once completed the NAS server undergoes numerous re-boots and a deletion of original RAID and a final re-build of RAID level again.
Why is NAS Burn in Testing (NASBIT©) necessary?
If within the designated time span the NAS servers are still running and with zero faults, it is considered suitable for rolling out to our customers. If there is a failure of any kind the systems is replaced with a new one, including hard drives and the process starts again, until the NAS servers passes with ZERO faults.
You would normally expect that this level of testing would be completed by the hardware manufacturers and so these tests shouldn't show up any faults. In our experience of testing hundreds of machines we do find faults, and we do send systems back.
The reason it is so important to perform this level of testing on NAS servers is that the uptime demands are so high. The slightest faults will cause outages and downtime. Once a NAS server is deployed, never again will you have the opportunity to take it offline and perform such detailed testing. Even if it were to crash, there is always a demand that it be put back online as quickly as possible, not left offline whilst thorough diagnostics are completed.
Always remember this is hardware and failures can and will occur even after burn testing has been carried, that is a fact of life we cannot avoid, but we do try and eliminate some of the hassle factor with testing. Thank you for buying from us, we truly appreciate your custom.
