Well ... this is very valuable. My both Mac's internal drives size is less than 400 Gb hence I thin 1 TB would be enough for me. I decided that I'll go with wireless NAS. I think to use SuperDuper (friend of mine recommended me it too), I think to setup scheduled backup on daily basis with incremental type. In my case it's not a business but rather Home environment hence I'll do it both to be on a safe side in case something happened with one of my Mac's and mostly for fun. I also think that I'll setup a personal cloud and etc.
- ZapNZs, assuming wireless NAS with ~ 1 TB size which one would you recommend?
Thanks everyone for valuable opinions.
I've not used SuperDuper myself, as I use Carbon Copy Cloner. But I am guessing SuperDuper has the same scheduling system as CCC. With CCC, what I do is I schedule a task to automatically create a carbon clone backup of the local hard drive Mon,Wed,Fri at 4:00 AM (when I am not using the computer), and it automatically creates this backup at the scheduled time (and if the computer is not turned on, it can turn itself on at this time to create the backup.)
If you plan to do backups
and a personal cloud, you would probably want an absolute minimum of 2 TB (maybe 3-4), because, if you already have 400 GBx2, you do not have much growing capacity. Opting for the larger size up front could prevent you from having to purchase new drives in a few years for space-related reasons. High-quality HDDs can be used for 5 years easily. Additionally, the price difference between 1TB and 2TB 3.5-inch HDDs is usually pretty minor.
If you go with the Synology Diskstation model 216J, you will have everything you need except for the drives (the unit holds two drives - you can use it with just one if you wish, and you can use both the 2.5 and 3.5 form factor.) The company is committed to their Mac Users, and their service is great if you have questions during the setup and usage process, or if you just wish to call them before buying and ask them more about using their NAS enclosures with your Macs (so you know everything you can before clicking the "Buy" button, such as what options there are for making multiple TimeMachine backups to the same physical drive.)
With that specific Synology enclosure, you can configure a RAID1 if you wish. That is, you would put two hard drives of the same brand/size inside the enclosure, and (after setting it up) the NAS enclosure would automatically save all files to both drives (so it is as if you manually saved every file twice - once to each hard drive - except this is done automatically and you would use the system no differently.)
How high of quality you want those drives to be is up to you. If you are using two drives in RAID1, that means you have a lot more leeway with how nice you wish to go since you have redundancy (if one backup fails, you have another drive with the same contents, and all you have to do is replace the failed drive and the system repopulates the new drive with the backup data on the older drive that did not fail.) If you choose to use only one drive, you will not have this redundancy.
In my personal opinion, I would call this:
Very Good - 2tb

Very Very Good - 3tb

(the other thing I like is how the write speed of this drive is over 220 MB/s, which is twice the speed
2tb

Best - 2-4TB - I consider this to be the pinnacle of storage, and use the Ultrastars extensively

When buying a HDD, it's worth being very, very careful who you buy from, in my opinion. For example, Amazon is
not a reputable place to buy many HDDs from IMO, because they are complicit towards (or simply permit) their Sellers who practice unscrupulous behavior of misrepresenting a drive's condition, history, (and sometimes capacity.) Many "Fulfilled by Amazon" HDDs that lead the consumer to believe they have purchased a new product are used/defective/non-working. Even some flash products sold directly by Amazon have been discovered to have been extremely convincing forgeries (obviously Amazon did not do that intentionally, but it goes to show how big that issue is there and how little control Amazon has over this problem.)
