I am hoping the community here can share their advice and insight regarding potential storage solutions for archiving copy jobs. Our current array only has enough storage for our daily fulls with 14-21 restore points. We also replicate with Veeam over a 100 Mbps dedicated ethernet connection to a DR site, but that array only has enough space to store the replicas. I need somewhere archive my file copies for additional restore points.
I ran a copy job against our daily fulls and the size was 6.6 TB data, 5.1 TB after compression. Ideally I’d like to have weeklies, monthlies, and a yearly saved to disk. Correct me if I’m wrong, but with the file copy job set for that scenario I’d have 3 weeklies, 11 monthlies, and 1 yearly. That’s 15 total fulls. At 5.1 TBs that’s 76.5 TBs plus change and overhead.
Unfortunately, my budget for this portion of the project is hovering around $4,000, so it’s looking like I’ll have to trim my ideal plan down to something more realistic - perhaps monthlies only at best or even more likely, something like quarterlies or possibly something in between like a copy job every 6 weeks.
Performance is not an issue whatsoever as this will ONLY be for storing copy jobs. It could be large disks with RAID 6 parity penalties, etc. I don’t really care if it’s a standalone NAS like Synology, etc or if it’s a rack mount 4U chassis like what I’ve seen on the Backblaze site. I really just need the most bang for my buck. I doubt that there is an online solution that would work, but I certainly am open to one though I only have a 30 Mbps internet connection to upload and download with. Whatever the solution, I definitely would require it to have some sort of option for expansion down the road as I’ll eventually have more money in the budget to add on to it with.
So, any suggestions on how to maximize the storage I can buy with that $4,000? I’d love to hear what others are doing. Any ideas would be greatly appreciated.
