Hello, i'm look for a cost effective highly reliable backup where chances of losing data is slim.

At the moment I have 12TB of storage that i'm on the process of compressing in to smaller files
one 3TB seagate hdd
three 3TB WD red nas drives

I have thought of many options and possibilities that i will list, some advice and recommendations would be great.

1.
Online backup: I tried using online back it takes rather a long time to upload, and to download files

2. IBM tape backups seems like a good backup but i read it takes a while to r/w

3. dvd-r backing up on dvd-r cost effective? time consuming yes

4. using raid, now i have been reading a lot about raid so if one drive fails i could rebuild but there is always a possibility of the rebuild failing. so would i need backup of the raid? raid six looks pretty awesome but what are the chances of rebuild failing and if rebuild fails what happens since two drives can fail


i plan on getting storage space to 50TB of movies for a movies on demand home system on my home network so i can watch them anywhere in the house

please help thanks

NAS drive with RAID will give you a backup solution for your main hard drives as well as redundancy in being able to not lose data from the drives with a drive failure.

Gee! You certainly have an unusual situation and quite a bit of data you want to backup.

I would think that backing up to large capapcity hard disk drives would probably be the most cost effective and efficient method.

1. I am neutral when it comes to the cloud. I understand the general principle. On the enterpise side of the market it is a form of outsourcing to a third party which initially is less expensive than doing it yourself.

2. I haven't heard tape drives mentioned in ages. During the early 1980's there were a few personal pc's that used tape drives. The tape drives were also used to load applications and games. It is just a dim memory now but I think the pc's with the tape drives were either Commodore, Atari, or Hasbro. On the enterprise side of the markjet there are still corporations with mainframes that use tape drives.

3. Using dvd's is not cost effective. It is also time consuming. Have you calculated how many dvd's you would need and what the cost would be?

4. RAID arrays were developed to improve the performance of hard disk drives. With the advent of modern ssd's, especially the new M.2 and PCIe ssd's, consumer interest in RAID arrays has declined. In addition there are some potential risks.

BTW - I have a friend who also has a very large film library. At last count he had 12 large capacity hard drives. His reasoning was that in the event visitors wanted to watch a movie they could choose a film from a large collection. Unfortunately things didn't go according to plan. When his friends and I visit it is to watch a sporting event on a large screen television. In 10 years we've never watched a film.

RAID are not really a backup solution, they are for disaster recovery and collecting multiple drives for space and speed on a server.

Tape backups are pretty pricy and if you think they are slow, writing 12TB to DVDs or even BlueRay disks is even slower.

What I would do is get an external multi-drive NAS with RAID setup and backup your data to that.

Hello Johnny thanks for your reply, the thing i want is like high storage and if a drive was to fail i do not lose any data, i really do not want to do back ups of backs ups it just seems over the top for me. I was looking at buying UPS by APC so if my power goes out, i can shut down my system safely.

i was thinking of getting two four bay Synology or one eight bay synology to make two raid 6 if that is possible 4 x 3TB WD red or i'm thinking about going with black for the five year warranty. one of the raids will be all movies i have so i use it with plex/rokuu

the other one will be used for my steam libary/installed games and a backup of my website

in terms of reliability and maintenance of a raid 6 what is a worst case scenario?

if one drive fails and rebuild fails what happens? as i did read that the raid can still work even if two drives fail, anyway to prevent rebuild fails?
