Does any product in the world have a better collection of testimonials than Tarsnap? Imagine getting a testimonial from Robert Morris. It's hard to get even a yes/no answer out of him. tarsnap.com/testimonials.h…

Tarsnap now has experimental amd64 binary packages for Ubuntu 22.04 "jammy". Ubuntu made some compatibility-breaking changes in 22.04 so it took a while for us to get these ready (usually supporting a new Linux is very quick). mail.tarsnap.com/tarsnap-users/…

For the record, @tarsnap is not presently hiring. If you recently received an email from "me" saying that I want to hire you: Sorry, it wasn't from me.

Sign up for Michael Lucas' mailing lists and get a free (digital) copy of his Tarsnap Mastery book. Seriously, do it. It's a great book.

Tarsnap Backup Inc. has joined as a silver sponsor. Thanks a lot, Colin Percival!

Since I've been asked: Tarsnap Backup Inc. has no direct exposure to Silicon Valley Bank, and as far as I'm aware has no indirect exposure either. It's business as usual here.

If any Tarsnap users are affected by the SVB meltdown, just send me an email and I'll be happy to make sure your data is safe despite liquidity issues. I just need to know that there's a problem and you still want to keep your data.

Our annual Ottawa developer summit would not be possible without the generous support of sponsors; the #FreeBSD Foundation would like to thank Tarsnap Backup Inc. for their gold-level sponsorship. wiki.freebsd.org/DevSummit/2023…

Donated $1000 to support Glen Barber's work on FreeBSD. He's an excellent release engineer and works incredibly hard to keep the project running smoothly. I hope other companies using FreeBSD will also contribute. gofundme.com/f/gjbbsd

Tarsnap is offline due to a hardware failure. I'm working on bringing it back. All your data is safe, just temporarily inaccessible. mail.tarsnap.com/tarsnap-announ…

Tarsnap's Black Friday sale is live! For an unlimited time, you can get three tools which I wrote for Tarsnap's internal use -- kivaloo, scrypt, and spiped -- for the low price of $0.00! tarsnap.com/open-source.ht…

Just updated the @tarsnap .deb packages to use the 2024 signing keys instead of the 2023 signing keys (which expire on 2024-02-01). If your apt-get is now breaking, you forgot to install (or update) the tarsnap-archive-keyring package.

Because we want to protect the most vulnerable members of our community, BSDCan @[email protected] is requiring face masks this year. Because I know people will forget, Tarsnap Backup Inc. is exercising its Silver sponsorship to include "vendor swag" in the tote bags: Two KN95 masks per person.

I just released Tarsnap version 1.0.41. This contains mitigations for a chosen-plaintext attack against Tarsnap's chunking algorithm which can leak its secret parameters.
