I am looking for a personal cloud storage or backup solution that supports a high volume of storage for a reasonable price and the fewest possible restrictions. Something that caters to my desired requirements might not exist, but suggestions for anything that comes close are appreciated.

The basic desired requirements are:

  • On the order of 10 TB of storage
  • No limits on file size
  • Should support just one user, without need for additional users to get more storage
  • Should have a desktop app for Windows
  • If backup solution: No limits on backup/restore capabilities or bandwidth
  • If backup solution: No limits on what can be backed up (e.g. external drives, network drives, etc.)
  • If backup solution: No requirements to back anything up (e.g. Backblaze requires backing up main drive)

What I can compromise on:

  • Sharing: being able to share would be nice, but not mandatory
  • Speed: dialup speeds are not reasonable of course, but a steady ~500 kB/s in each direction is plenty fine
  • Security: as long as the software doesn't try to read my entire private storage, and I can choose what exactly to store in the service, things like full e2e encryption are not a requirement

Here are some services I have looked at, but each has significant drawbacks:

  • OneDrive:
    • Every plan requires either to split storage into 1 TB segments, or pay a lot more ($10/TB). I am also not sure whether it's possible to use multiple accounts for the "home" tier on the same computer
    • 10 GB file size limit
  • Box.com
    • Minimum of 3 users, making the price unreasonable
    • 5 GB file size limit
  • Sync.com
    • Two-user minimum, making minimum price $30/mo with half the space unnecessary. Theoretically this service is the closest to what I want, but the price might be the upper limit of what I'm willing to pay, not mentioning the psychological aspect of paying for a superfluous user
  • Backblaze
    • Requires backing up Drive C
    • Not a real backup service—it auto-deletes files that aren't currently in the system after 30 days, including unused drives
    • No backing up network drives

Every other service I have checked is significantly more expensive.


You could use Backblaze B2 which is quite inexpensive per GB.

It doesn't have a desktop client per se, but you can use the free Cyberduck software as the desktop client.

A couple others I heard of recently are Sia and Storj but not sure if they check all the boxes you posted. The idea behind them is interesting (distributed encrypted network comprised of unused space).

  • Thanks for the response. It looks like Backblaze B2 and Storj are significantly more expensive than Sync.com and some other solutions, but it's definitely something to look out for in the future. – Ynhockey Apr 15 at 12:42
