There are Bad and Good news for Seventeen-Or-Bust... Which do you want to hear first?

Built-in SQL compression doesn't typically do much. I know it does nothing on Oracle. Can you export un-compressed then use 7zip? I would be surprised if it isn't less than 10G.

I don't know about Oracle, but MSSQL's internal compression isn't too bad. I'd compare it to a low level of zlib, like a level 3 out of 10. Fast enough to be useful and compresses enough to get what would normally be 70 GB down to just 20 GB.

I'm sure 7z or RAR could do much better but that would mean doing a full size backup and compressing separately which would take a lot of time... the extra time to shrink by another 5 GB (just an example) would probably not be made up in less time to back it up to the cloud, and bandwidth isn't really an issue.

There are some 3rd party MSSQL plugins out there that give you more backup compression options like setting the compression level and have a better method, but they're not free.

I realize this thread is pretty old, but I have a few questions.

1. Anyone know how much of the results were salvaged from user-submitted log files?
2. Was the project insured?

I know that payouts from data loss tend to be pretty low - like tens of thousands of dollars at most - but that's still better than no compensation.

I just saw this get posted over at Yahoo groups:

Congrats to Szabolcs Péter and PrimeGrid and Seventeen or Bust for the 9,383,761 decimal digits prime:

10223 * 2^31172165 + 1 ( http://primes.utm.edu/primes/page.php?id=122473 )

5 "k" remain in order to prove John Selfridge's conjecture,

Dang! Congrats! For the first time in years, the top10 list is not "all gimps and mersenne" anymore...

Many congrats for this splendid result!
I am so happy to know about that!

That needs to be fixed. Quick someone find M50->M54.

Now I'm happy to have put in lots of CPU time clearing exponents for that k :)

That is excellent news. I hope this renews interest in the project. Given enough contributors, I'm confident that Seventeen or Bust will recover from the data loss, especially with Moore's law on our side.

It could barely have come at a better time.
