They have a Sydney region, and 30-day ("Cool") and 180-day retention options ("Archive"). It was pretty hard to find the egress pricing and I'm not totally sure I'm reading the right price? Microsoft Azure Blob StorageĪzure is the #2 cloud. Would each API request take an hour to return? What if I need to restore many files, do I need to rewrite my backup client to work in parallel? Or do I copy to other storage first? There's probably good answers to these questions but I don't have them.ĪWS' egress fees are famously expensive and opaque, though it looks like it's cheaper than Google in Australia. And I didn't really feel like wrestling with the tradeoffs of "Glacier Flexible Retrieval" ($43/TB/year storage). But their instant-access 90-day retention offering, "Glacier Instant Retrieval" was much more expensive ($166/TB/year storage) than Google's. Amazon has 5(!) classes of blob storage, from "Standard" to "Glacier Deep Archive".Īmazon has a Sydney region, which is probably fast to upload to. The market leader and inventor of this segment. There's a high-speed Sydney region, the security posture is great, I'm very familiar with the platform, the tool ecosystem is large, but the egress pricing, particularly in Australia, is extremely expensive. It's a good fit for backups, with decent storage pricing ($72/TB/year) and still instant retrieval when needed. I was already using Google Cloud Storage Coldline for Arq backups from my laptop. Regional Data Transfer Out to Internet (Australia)ĭisclosure: I'm employed by Google, and use Google Cloud Storage at work. Here's the spreadsheet I made to evaluate ( original in Google Sheets): Name This was frankly a bit disappointing, as I was hoping to find something better than what I was already using! Options Also this great comparison on the Duplicacy Forum. You should probably read Anthony Agius' Cloud Archive Storage Comparison in addition to mine, because he goes deeper into niche players that I couldn't be bothered evaluating, and considers restore fees. I didn't bother considering restore fees. Your mileage may vary: This is a pretty rough, not very rigorous, somewhat "vibes-based" comparison. Egress fees are generally high, so you really don't want to use a backup software that has to read back data as part of normal operation. So my expected value of egress fees is maybe one tenth what's quoted. Or maybe I can poke around the data on a VM in their cloud, and only egress the really interesting stuff. If my local data fails, I'll probably be happy to pay a bit to restore. I don't really want minimum retention period of a year because then I'll feel very locked-in.Įgress fees: I don't care so much about network egress fees because I think the risk of me losing this data locally is pretty low, about <10% each year. But I probably want to start thinning backups out after 90 days, and delete altogether after a year. I'm happy to keep the backups for at least 90 days. I want backups to be quick, so they should probably have an Australian region. What I care about: I have about 1TB to back up. Some providers have 'minimum retentions' where you have to pay for at least 1, 3, 6, or 12 months of storage. There's usually storage fees (per GB per month), sometimes 'restore fees' if it's in deep storage, and sometimes network egress fees when you want to get your data back out onto the public internet. The pricing is fairly tricky to work out. I chose which cloud backup software I'd use (winner: Duplicacy), but where should I upload my backups to? There are lots of blob storage providers. After I lost a hard drive to (possibly) a lightning storm, I re-evaluated my backup strategy.
