I am having second thoughts about using duplicati + B2 as my backup solution. Reason: I realized that I may well be paying 15 USD per month to store about 3TB of backups in B2. And then I saw that Backblaze Personal Backup would costs me 5 USD per month (or 4 USD on a 2 year plan). And that includes unlimited storage. Need I say more?
But I’m not giving up on duplicati so easily. So let’s make a proper comparison and I’m sure, duplicati will come out better at least for some scenarios.
Most obviously, duplicati + B2 is cheaper if you need less than 1 TB in the cloud (not that that equals a good bit more data on your harddrive, given duplicati’s compression). So that’s that one sorted. Unfortunately, I need more than 1 TB.
Next: if you have multiple computers to backup and your total backup archive is less than the number of computers in Terrabytes (e.g. If you want to backup three computers and your total backup archive is less than 3 TB). That is because Backblaze Personal Cloud charges you 5 USD per computer.
And here is one more easy scenario: you want to backup from a linux machine. Backblaze Personal Cloud simply doesn’t have a Linux client. Of course, you can complicate your calculations somewhat by keeping your linux machine (e.g. a NAS) out of the picture and using a different solution for your other computers. But I’ll leave that to you and your calculator.
Any more arguments pro duplicati?
Well, I am not going to do a detailed feature comparison because it looks like Backlblaze has a pretty good feature set but maybe someone else has identified some serious difference?
To me, it seems to boil down to the question whether I want to have total control over my backup archives or depend (to a larger degree) on a company and how much am I willing to pay extra for that? As we have seen in the case of Crashplan, even large companies can suddenly discontinue your backup plan causing all kinds of issues, not just because you need to find a new solution but because they have your data in a proprietary format that you can’t just transfer to a new provider. In other words, you have to upload all your stuff again and, most importantly, any deleted files you still have backed up will be lost forever, unless you download them from the old provider and upload them again to the new provider, potentially causing all kinds of confusion, because they probably don’t have their original dates on them any more. And I won’t even start thinking about the older versions of not deleted files, which will also be lost.
Such problems are avoided completely with duplicati. (Instead, you might spend your time solving other problems.)
Have I missed something?
