CrashPlan

I crashed a disk. Estimated recovery time for my 2TB: 10-40 days Initially it was estimated at 40 days, but it speeded up, "only" 4 left days now after 7 days passed. So if it persists it would be a total of 11 days. The speed seems to vary with the times of day (slower when everyone is using it; faster at night).

I like the system, and the recovery speed/performance can be acceptable, depending on your needs. The price advantage is definitive, but you must be aware of the slow recovery.

I think I might prefer an alternative faster solution in the future

Used to be the best, but now it's barely tolerable.

The worst part of Crashplan is that it is basically a virus. What I mean is that it is designed to never shut off on your computer or close, even when you force close its process and tell it to not autostart with Windows. This is terrible because Crashplan is a terribly coded Java program that takes up tons of memory and makes my decent gaming build sound like a jet taking off 24/7. I used to like how it used up my my 8 cores and vast amounts of memory to back up faster than any other program, but since you can't get the background process to stop taking resources without uninstalling, it makes running other programs on your computer laggy. Don't even think about using this on a standard run of the mill computer.

And then you run into the customer service side, where despite the fact that there's this one guy who genuinely cares about their users, they will delete your data if you're so much as a day past schedule without paying (because a credit or paypal can have a slight issue that causes the charge to stall, you're done for). They bill in increments instead of right on the spot, so getting everything set up perfectly for the next cycle is a hassle.

They also silently took down their phone app which allowed you to pull programs from online while on the go or even look at your backup when away from the computer. That is a total bummer, especially when you now need to pay more for this.

I was once willing to pay the larger costs on using a commercial grade program to back up my priceless family photos, but now I'm just waiting for other programs to catch up backing up my data so I can finally uninstall it and cancel my billing cycle.

There is now a Business version but the upload speed is atrocious now. Not what it used to be.

its so hassle because you need to install apps to unsubscribe https://support.crashplan.com/Troubleshooting/How_To_Combine_Multiple_Email_Alerts

Crashplan has been bought out by Carbonite and will be effectively gone by October 23rd, 2018.
