I've been using OneDrive for cloud storage, as have my wife. I currently have the 25GB legacy storage + 50GB subscription for OneDrive. My wife does not have the legacy storage and has filled hers, so I have a few options:
1) Subscribe her to the $1.99 per month for 50GB plan.
2) Ditch OneDrive, and subscribe to the 100GB Google Drive plan for $1.99 per month.
3) For $70 per year, I could get Office 365 Home and give each family member 1TB OneDrive storage.
Advantages: Easiest option to use and implement across desktops and mobile. Probably redundant. Low cost.
Disadvantages: In the case of Google Drive, would require re-uploading everything to Google. And in the case for either option, I would be using the services of two large tech companies, who mine your data. And some
recent changes to Microsoft's Services Agreement have some worrying language. In particular
* "[U]se of offensive language and fraudulent activity is prohibited"
* "Don’t publicly display or use the Services to share inappropriate content or material [...] involving, for example, nudity"
Not that I upload nudes to a corporate cloud, but algorithms do make mistakes. Also, I do keep some non-DRM copies of RPG manuals around. Who is to say that they won't get flagged as pirated material? Nobody wants to upload gigabytes of data to a service, just to have it all locked out one day.
So, I considered setting up a redundant home NAS again. I do have a single drive on my network, but would need something with RAID to store photos and family videos safely.
If I used a two bay option from QNAP or Synology, I would be looking at about $350 for a pair of 4TB drives and the 2-bay enclosure.
An option that would be more fun would be to build something myself. Possibly a compact server with BSD and ZFS. While more flexible, it would be even more expensive than the prebuilt option. And the prebuilt option would take more than five years to pay itself off vs the Office 365 subscription.
While I contemplate what to do, I guess I'll continue making additional copies of my data on Blu-Ray discs.
