There are certainly still plenty of things that can go wrong, but that's always going to be the case. We can come up with tons of edge cases if we want to -- we're a smart bunch. :)
Ultimately, you have to decide how much the data is worth to you and how well it needs to be protected. We were having a discussion with Fujitsu the other day and talking about storage system snapshots/replication vs. backups, and the guy said, "Well what happens when both your primary and DR site are down?" Yeah, it's something to consider, but you have balance the "9's" and the costs and do what's right for your company and your data. The data is only going to keep growing, and standard RAID and tape libraries are not going to be able to keep up. -Adam On Sun, Sep 15, 2013 at 10:58 AM, Adam Tauno Williams < [email protected]> wrote: > On Sun, 2013-09-15 at 07:39 -0700, Andrew Hume wrote: > > it doesn't because it doesn't address that issue at all. > > this is simply an issue of how does one store the data reliably > > when its barely all you can do to store it once. > > now that erasure codes have freed us from the tyranny of RAID, > > folks seem empowered to store prodigious amounts of data. > > BUT, this Big Data comes with different expectations, one of which > > is that there are no backups (in a user visible sense). > > almost no one can afford the traditional form of backups (as > > completely separate copies). > > Have you looked at OpenDedup?
