Network Attached Storage for Backups Reviews and Recommendations

An existing customer asked me to recommend a Network Attached Server (NAS) for use in backing up their primary computer and, rather than keep the recommendations to just them, I thought I’d share a few thoughts. The limitations of this review are that I haven’t physically handled most of them, and this not be a comprehensive review of the options out there as there are altogether too many to choose from, so this will only cover a few select units. Also, there is no way in a review like this to cover all of the features offered in each unit.

Our goal here is to back up a a single computer using Acronis True Image Home, and there must be capacity for multiple copies of backups, going back a month. The system to be backed up is a typical small office computer, with about 250GB of hard drive space used. A NAS is preferred, because it can be placed in a physically different location, reducing the risk of theft during a break in.

The choice between the TS-251 and 251+ is really about the processor. If you’re willing to part with the extra $90, you’ll definitely get farther with the 251+ . In either case, I do wish the NAS manufacturers would go ahead and move into the i series processors, even if it does cost a few extra dollars to do so.

Synology DS216j Diskless System NAS DiskStation

Bottom line : I DO recommend this system for very small business and home use. I wouldn’t use it with more than 2 computers at once, but it is a solid device with a lot of positive features.

WD My Cloud 3 TB

Bottom Line : I do NOT recommend this for business or personal use, except in very specific circumstances.
My customer picked this up (model WDBCTL0030HWT-NESN) , quite inexpensively and, from its spec sheet, it seemed like a good option. Once we started using it, however, its reality fell far short of expectation. As a result, its review is considerably shorter than those I do recommend.

GOOD BAD
Easy Setup Poor Security
Low Cost
Drives are included and installed

Drives are not hot swappable

While I only had my hands on this unit briefly, the security problems I ran into were as follows :

  • Returning to the setup screen in any web browser allowed immediate ability to edit the configuration of the NAS, without being challenged for a password.
  • UNC (\\servername) from a Windows based computer allowed full, unchallenged access to the data stored on the NAS. This makes the data vulnerable to intentional or unintentional deletion by an employee, or worse due to malware, ransomware and infiltrators.

Even at home I have serious reservations about this device, and I wouldn’t recommend it to anyone until the company updates the firmware to ensure basic security is in place first.

If you have more than 2 computers to backup, or are planning to use the NAS as a primary file server, then you should consider a 4 Bay NAS, like the QNAP TS-453A. More on that in another post.
