I used tarsnap for years, but as my data got bigger and I really wanted to have multipe offsite backups with different providers, I moved to restic. I loved tarsnap - it's a great product. But restic feels very similar but you can backup to your local HD, a remote HD, or "the cloud" and everything is the same CLI commands.

What provider(s) are you using?

I've been using tarsnap for years and am in the process of migrating away from it. Things that are not cozy: 1) There's no way to monitor your monthly spend per host/credit left on the account/etc. apart of logging into your account in a browser and manually keeping a spreadsheet. There's no web API to do it. You get an email warning when you have about 7 days of credit left. That's it. 2) Nothing is "a precious few…

I found restic is a prety cool alternative. (No hosting though, I am sending restic backups to a private server/vps)

I really wanted to like Tarsnap and gave it a good hard look for my backup needs. Ultimately my problem was that there's no way for me to gauge how much the service will cost me. Going just by the amount of data in my home dir, it would be cost prohibitive to upload to Tarsnap. The site does assure me that thanks to compression and deduplication, the actual cost will be far less than I might estimate, which is great! But also, as far as I can tell there's no way to have the client give me an estimate of "here's how much data you actually have once the secret sauce is applied". So while the dedup and compression might make the costs far more reasonable, I won't actually know until I pay to store some data. Which means I might find that suddenly I owe Colin a lot of money if the size savings aren't very big due to my data not being very amenable to those measures. That's not a risk I'm willing to take, so ultimately I pursued other options.

Earlier quoted context omitted.

A hard drive under the bed is not the only alternative to tarsnap, you can use any of its numerous competitors that are also maintained by professionals, whose whole business is also running a backup service. Say rsync.net or borgbase, which are at least 10× cheaper than tarsnap last time I compared them, and can be used with restic or borg which are much faster at restoring even relatively small amounts data (forget…

> A hard drive under the bed is not the only alternative to tarsnap Also you can back up to the hard drive under your friend's bed, and they can back up to the hard drive under your bed. If you're even slightly technical, or have a friend who is, I'd recommend both of you buying the cheapest Kirkwood NASes you can find on ebay, throwing Debian on them, and becoming each other's backup buddies. https://forum.doozan.co…

That's what I do! I have a couple of friends from college and we back up to each other over a VPN. It's a very nice solution to the off-site backup need.

Does anyone know how it compares to restic or duplicate?

I use restic. Restic offers everything advertised on the tarsnap website (deduplicated snapshots, e2e encryption). I pay $6 per terabyte per month using backblaze's cloud object storage. Wasabi offers 1TB at $7/mo. S3 costs $26/mo, but glacier is only $3.6/mo.

Storing one terabyte of data in tarsnap costs $250 per month.

yep it's what i'm using right now

restic, and my own computers and storage, and the occasional rented device (VPS or similar, typically)

i find that the hassle of setting up my stuff is still preferable than having to worry about managing bills, subscriptions, and third parties just changing their policies

Sounds like it's just a worse Glacier setup then? Amazon has Pre-Pay in a semi-open beta. CloudFront has 1TB/month free- knocking a large chunk of a restore's cost. (Note- you should have either encrypted your stuff yourself and/or S3 authorization/access control still works over CF) At what seems to be $5/TiB/mo cheaper than anybody else.

Tarsnap has a nice security model, and it’s quite a challenge to convince any open-source tool to match it.

OP's cost estimator tells me it would cost a cool $250 per month to keep a terabyte of data backed up in Tarsnap. The same amount costs me $8.25 per month with Backblaze. That's not very cozy!
