ParmaDrives now come with ParmaSwap!
If you actually have friends, one of them and yourself can buy a ParmaDrive, and your disks will remotely back each other up (encrypted, of course).
Say you both had a 16TB drive, then each of you can back up 8TB (50%) to the other.
Each night, the disks do a sync, and only changes take up extra data.
It keeps 7 of the last daily backups, 4 weekly backups, 6 monthly backups, and 4 six-monthly backups, allowing you to recover accidental deletions in the past. You can mount a read-only historical file system and copy out what you want.
Of course, the finer configuration options can be customised on request.
The real benefit is that you can deGoogle yourself from data storage, so their creepy employees can't masterbate to your homemade sex tapes, without paying.
If you extracted all your data without ParmaSwap, then your data is in one location, and at risk of loss (single point of failure).
You could do manual sync to an extra drive, and bring it home to update/sync from time to time, then put it back in a remote location; but that's shit, and risky.
You could back up to a VPS, and encrypt it yourself, but you'll pay a lot for storage, I mean ridiculous, and be exposed to forever fees, and difficult to move when they jack up prices (crashplan did this to me - they got me with fair prices initially, than increaed the price enormously, and it took years to get off).
Anyway, with 2 ParmaDrives and ParmaSwap, either both yours at two locations, or one for a friend, you get a discount for the double purchase and combined shipping, and you won't have ongoing subscription fees for data.
You can self sovereign store your data, which arguably might be more important than your bitcoin... Depends how good those ex-girlfriend sex tapes are, I suppose.

I want to add, you can also do ParmaGoupSwap, but it's not ready yet, pilot volunteers welcome. This is like ParmaSwap but more redundancy. You can back up your data to more than one person, and you can offer space to more than one person. This way you reduce the reliance on someone to have your back in a data emergency.
Much later on, there will be ParmaSwapBay. I'll leave that to your imagination for now, this is getting too long.
