      Software raid won't need a raid controller and has very low CPU and RAM requirements on HDD arrays - if you use a reasonable file system.

      File system does not interact with the RAID array. RAID doesn't even know if it has a file system.

        So, disregarding the fact that this seems to be a bit of a fool's errand or a case of being set up for failure..... something like this might work from a hw perspective https://www.45drives.com/products/storinator-q30-configurations.php

        Those are never meant for SMBs to use, those are RAIN cluster nodes. Incredibly risky in a RAID configuration. BB never meant for that design to be used outside of a disposable node, massive cluster setup. It's not a mistake on BB's part, it is SMBs misapplying knowledge from another field, or in the case of 45drives, a vendor preying on SMBs not knowing better. I've had to rescue companies that made this mistake with much smaller arrays.

          I gave up on reading all of the comments after a while, but has anyone touched on the target getting bogged down with all of the simultaneous backup sessions running?

          No, as there is no information about the use case, we don't have any idea what kind of load it will experience.

            If we're talking about keeping the software side of things free, would amanda / zmanda be an appropriate solution?

            I think UrBackup is better there, but that's beside the point. Veeam Windows Agent is a requirement that can't be reconsidered. So it is what it is.

              And to take it a bit further. What will happen if the backup is truly lost? There is a dollar amount attached to that problem.

              From what we gathered, no. There is no business logic behind the decision, it's a purely political situation for everything from the budget, to the needs, to the tech.

                  RAID10 makes no difference if that is what you mean. You can have a disc failure on rebuild and then you have nothing.

                  But you are way less likely to have one, and the bigger risk of UREs isn't there. Yes, it's a numbers game, RAID 10 has better numbers (at higher cost).

                        I would use the arrays as individuals so you can take one of them out of commission if you like and run backups on the others instead. Maybe even put it on two servers instead of one.

                        That's true, there IS a value to splitting up arrays. But there is also complexity and a loss of speed. Pros and cons. Multiple servers would be really tough, as the chassis is a bit part of his expenses.

                            Can you confirm, I know it was mentioned, but I thought it was mentioned only because it was free. Not a mandate that it be used for any other reason than the cost to acquire it.

                              He definitely said twice that it was handed down as a mandate. It was never something up for consideration, it just wasn't part of the original post.

                                Time to rebuild a 8TB drive at 100 MB/s is 8000000/100=80000s=22 hours. That's nothing.

                                That's not reality. RAID 6 rebuild on 8TB is weeks, often months. 100MB/s is not the rebuild speed. You'd have to anticipate at least 2-3 weeks for a rebuild to happen.

                                BS.

                                OK, let me clarify that. If you take the array out of production it's a realistic number. BTDT. Which you can if you have split arrays and don't stripe it all. Also a little logic is needed on where the backups go.

                                  How are you determining the amount of storage that will be needed?

                                  I've been given the target by another team, so that is out of my hands. The rest of the company use B&R, but they do not plan on introducing this to UK side until 2019 (sometime in 2020). So we have been told to use up to 15k to get ourselves backed up until then using the Veeam Agent Free Edition, then in 2020 we will be incorporated. Out of my hands, but is what it is.

                                  Makes sense with what you say about the backup server and the storage behind that server/attached to the backup server. But thats not where we are here until 2020.

                                    Yes, you must have missed it. Veeam AGENT Free is a requirement.

                                    My takeaway was that the free agent was the proposed solution, not necessarily a requirement....

                                    .... going back to the "planning" that got us here, either I'm underestimating the capabilities of the 2020 introduction of a veeam server or someone thinks that they'll be able to fire up a server in a year's time and point it at the existing backups and say "these are yours to manage now".... which seriously defeats the point of putting something like a "real" veeam server in play that takes backups at the hypervisor level even if it can ingest the existing data and take over managing the backups.... "Planning" along these lines is the only reason I can think of the veeam agent being a hard requirement

                                    ... OK you found the required part while I was typing this up

                                        "Planning" along these lines is the only reason I can think of the veeam agent being a hard requirement

                                        NONE of this is based on planning, at all. This is 100% politics and the OP has no say in it. It is a non-technical mandate from powers on high that are not considering any business need or ramifications.

                                          Agree 100%... The road to hell is paved with good intentions; wanting backups is never a bad thing, trying to do them like this is just asking for trouble.

                                            Not sure that this is good intentions. My guess is departmental fighting over a budget. But who knows.
