Take a look at Arq. I began switching over to it before Code42 announced they were shutting down CrashPlan, and I've been happy with it. And if you do one-day decide you want to put some of your data in a cloud, this supports that as-well.

Arq sounds interesting.

Just for completeness sake, I see in their features section:

"You can back up to your own Amazon Cloud Drive, Amazon Web Services, Google Cloud Storage, Google Drive, Dropbox, or OneDrive accounts, or your SFTP server or NAS"

So local options are only SFTP and NAS? do you know what do they mean by NAS? i.e. they support a branded NAS like Synology, or maybe OpenNAS servers? any info on this would be great as that would save me some time downloading the trial and setting up stuff just to figure this out :)

From the documentation, it's only SFTP or whatever network volume that Windows itself can mount.

I use Arq to do both local and cloud (S3) backups. The local backup isn't limited to any particular NAS or local FTP destination; mine just goes to a cheap external USB drive I have plugged into my mac.

The option is called "A folder on your drive or NAS", and asks you to specify a folder, so external hard disks should work fine.

Thanks, for some reason I was convinced Arq was Mac-only.

It's not clear to me whether it's a point-in-time backup, or continuous like Crashplan, do you know?

It's incremental. The default schedule is to do hourly backups, but you can customise the interval and/or set up Arq to only backup on certain Wifi networks.

Thanks, so it's not constantly monitoring the filesystem like Crashplan, right? Doesn't it take a toll on the disk performance when it's scanning?

I have decided to go with Arq and Glacier. Although Duplicati looks pretty good too.

Have you calculated the cost of a restore scenario?

It seems it's $0.01/GB or am I missing something? Pretty new to AWS.

You get request changes, archive charges, network charges, etc.

How can you calculate these? I have around 100GB

Since restoring will be a very rare occurrence I think it will be very affordable. Unless I am missing something.

The AWS calculator is pretty useful too: https://calculator.s3.amazonaws.com/index.html

"As of 21 November, 2016, Amazon has simplified their pricing for retrieving data from Glacier. You pay a flat per-GB rate for the data you retrieve. The rate depends on which tier you've chosen -- Bulk, Standard or Expedited."

Any idea if Glacier cheaper than Amazon Cloud Drive? I'd started using Cloud Drive when their storage was unlimited, but I'm revisiting that decision since they've added storage tiers.
