Our organization produces about ten gigabytes of information every day.This information must be preserved for years to come, and therefore the question of a reliable archiving system has arisen.
I propose to use for this dvd drives.
Having estimated the cost per gigabyte on dvd and on a 3.5"hard disk, the hard disk turned out to be cheaper.It’s unnecessary to copy the convenience of copying, cutting a few terabytes on dvd is not a simple and fast task.

I ask for advice on choosing an archiving system.How reliable are conventional hard disks for such an application? Maybe in recent years there have been new archiving systems that I don’t know about.The main criterion is the possibility of building up an unlimited amount.

Thank you in advance.
  • Can you tell what kind of information?
    Database? Office files or something specific?

Distributed file systems.For example LizardFS, MooseFS.
You can GlusterFS, but I met negative reviews about it
Does
produce several tens of gigabytes of information every day?
- are these two or twenty?
We, for example, must be stored for some years as ISP-generated netflow.
About 10 gigabytes are generated per day.
A week is almost a hundred.In a month, something from 300 to 800 gigabytes.
Therefore, for the time being, we have so far settled on the fact that we periodically buy hard disks and merge them, and then store them in a subfield.
In my opinion - this is the easiest and cheapest version without cassettes, shelves and other things.
If it is a pity to lose the information, then only NAS with raid1 with monitoring of the raid.Otherwise, one day you can not catch the data on the physical media.
