In choosing between QNAP operating systems, the choice boils down to one that pits QES vs QTS. Each of them brings specific assets to the table, yet a number of differences exist that make a final selection one that needs to be based more on the individual needs of the user or the entity that purchases such products.

Efficiency

Both QES and QTS are built to allow standard tasks to be addressed quickly, yet it’s important to note the way in which this is achieved. With the QES, the areas below serve as main components:

• Real-time data compression
• Deduplication at block level
• Thin Provisioning with Reclaim.

When it comes to QTS, the Qcenter eliminates the previous issue of logging into each NAS, which expedites the work required. An employee can use a central management platform to receive visual summary charts. A quick set-up of NAS systems is also possible, which can be a boon to data centers. The fact that it can be installed on a virtual machine and can be managed through a firewall make it even more valuable.

Security

The growth of internet security flaws makes debates about the merits of QES vs QTS seem unimportant, given the threat of theft of any number of items, including intellectual property. However, QTS allows for remote security to be in place, which allows any legitimate user to obtain access from both work and far beyond, knowing that they’re protected from any unwanted intrusions by hackers or other potential threats.

QNAP Operating Systems consistently provide coverage, yet can sometimes be vulnerable to a problem. QTS had flaws detected during its service, with one of the more recent taking place in October 2015. That's when it was discovered that using the Apple Filing Protocol allowed remote users who hadn't been authenticated to not only read, but write arbitrary files.

Backup

QES takes into account the possibility of a crash by its SnapSync that’s block-level. That means that remote access is possible to make sure that any quick recovery of data is available from a backup system. Also, the fact that it uses a dual active controller offers an added layer of protection.

Using smart version control, QTS backup files can be saved by determining beforehand how many times backups will be required. This may come at the end of every hour, every day, week or month, which can help avoid lost data by selecting a version that came just before any problem developed. It also may be a viable solution to rotate multiple versions that have been saved.

Storage

Using a graphical interface, QTS allows a quick check of the Dashboard to assess the allocation for system storage. The Storage Manager helps organize things like disks and ISCSI storage by getting the most out of storage use and making the management of the hard drive easier. That management can be spread over more than one RAID group.
