I got stumped by a question that I got while on the road this week, and I thought I’d throw it out. A user came up to me who has a 300 TB Oracle database that generates 3-4 TB of transaction logs a day. They are currently unable to back it up — at all. …
it’s no secret that I’m a fan of OST. So any of the vendors that I work with that don’t support it get to hear me say on a regular basis that they need to support it ASAP. So I read with excitement that Sepaton demonstrated support for OST at Symantec Vision. Written by W….
I read with amusement Lauren Whitehouse’s latest blog entry about global dedupe. I’m not saying that I was laughing at anything she was saying, per se; I totally agree with the whole article. I was amused by what customers said about global dedupe. Written by W. Curtis Preston (@wcpreston), four-time O’Reilly author, and host of…
I’m surprised that Dipesh Patel of CommVault joined the “dedupe ratio doesn’t matter” chorus with his blog post “How to analyze dedupe ratios and its impact on cost savings.” I’ve met him and know him to be an intelligent person, so I’ll post this and hope for the best.

In a recent blog post, I praised Veeam and others for having a work-around for VMware’s limited VSS implementation. They’re still on a very short list. But now they’ve really out-done themselves. The VRanger guys better watch out or they’ll be looking at Veeam’s taillights pretty soon. Written by W. Curtis Preston (@wcpreston), four-time O’Reilly…
A press release went out today about IBM’s TSM 6.2. Among other things, it says that TSM now has source dedupe! As big as that news is, there’s another piece of news that is even bigger. Written by W. Curtis Preston (@wcpreston), four-time O’Reilly author, and host of The Backup Wrap-up podcast. I am now…
Last month I wrote a blog post about how I thought that Hyper-V was ahead of VMware in the backup race. If you haven’t read, you should read it before reading this follow-up. Before you read that post, however, you should probably know about what’s in this postthat explains Windows VSS and why you should…
A few weeks ago, I posted a blog entry about building my own backup system using rsync, instead of using MacOS’s built-in Time Machine. I did this for a number of reasons. Well, it’s been a few weeks and I’ve learned some lessons. So I thought I’d share them! Written by W. Curtis Preston (@wcpreston),…
This question has come up again. For what it’s worth, I’m still firmly in the camp that says that it is possible to have a complete backup system based solely on snapshots and replications — as long as you can address the criticisms that people have against the idea. So I thought I’d throw out…
Dave Raffo announced in Storage Soup that Quantum announced yesterday that they had found a new OEM for their DXi line. I hope for their sake (and their investors’ sake) that things work out better for them this time. Written by W.
