Best way to backup big data...
-
No 2nd building but I'm sure they could find a home to host a secondary NAS somewhere. You think that's best option?
-
I like keep a copy in Tapes.
If you can afford it, LTO-8 is a good option.
-
@joel it could work.
Depends on the goals / business needs. Are they looking to just backup so if the primary fails the data is there, but what happens if the building burns down? Both sets will be lost.

We use Exagrids and tape. Though for only 45TB you could just build a box and Colo it. RHEL/CentOS now have VDO support so you get dedupe and compression on those volumes.
A supermicro box with 24 8TB drives is around $13K. That's around 90TB in RAID 10. I don't know pricing for smaller because we build with those. But it shouldn't be too expensive to build your own and ship to it off-site.

You looking to backup the server and the NAS? What does the server do? Is it virtualized? What brand NAS? How much data is on each device?
-
My first question is ...
Seriously? Forty-Five Terra Bytes?? good god - what are they storing?
That seems like a huge amount of data... And you damn sure don't do that in a weekend...
-
the initial push of something of that size will suck.
But what is their change rate?
You could seed it manually and then resume sync.

I dont know anything as much as they want to backup 45TBs lol!
I'm trying to schedule a meeting to have a chat and find out more so will come back once (if) they come back to me...It was someone I met over the weekend so I dont know so much just yet. Just making initial enquiry to suss out what others do with this amount of data. -
Veeam to StarWind Virtual Tape Library (VTL) with a BackBlaze backend connection to back up all that data.
We're getting ready to pilot this kind of setup. VTL integrates really nicely into a tape based infrastructure with little to no mods needed.
Edit: For on-site storage we set up either a Storage Spaces Direct cluster or a Converged cluster. In this case it would be Converged with close to 1PB of available storage (2x nodes + 1x 102 bay JBOD)

If it's large files likes raw video then compression and deduplication is unfortunately of very limited use.
We just use a standard supermicro 4U server with 24x3.5" drive bays. Running software RAID-6 with very modest hardware specs we have 250MB/s sustained write and 700MB/s read. More than enough to saturate a dual gigabit network link.
Two RAID-6 arrays with twelve 3.5" 10TB enterprise drives in each will give you around 200TB of storage. Or perhaps three RAID-6 arrays with 8 drives in each giving you about 180TB.
The most money in this type of config will be in the drives themselves. 10TB Seagate Exos X10 are about $330 each so 24 drives is $8K.
