How many of you have heard that compression and deduplication just don’t belong together? Like oil and water. I know from experience, when I worked for EMC, the Avamar sales reps and the Data Domain sales reps would tell their customers that the best thing to do if they had encrypted or compressed primary data, that they uncompress it to get the savings in their backups that deduplication promises.
This is wrong on a number… Read more »
In my career I have done a lot of traveling. Well at least I thought I had. I am just returning from a trip to Israel where I met with the Storwize engineering team and CTO (Yoni Amit) as well as some of the greatest minds in the storage industry. I have to say, Steve Duplessie’s blog was right on when it comes to the technology capabilities that exist in that country. As most… Read more »

Though it was my wife that came up with this name, I really think it fits. It seems like every 3 to 5 years I end up at a new place with new challenges and new lessons to be learned that… Read more »
There is a lot of discussion around data deduplication for backup these days. (I wish I could deduplicate all the turkey I ate last week.) In fact, Gartner claims that “…by 2012, deduplication will be applied to 75% of backups.” And when asked “Why?” the response was “…deduplication is too compelling to ignore.” But I say “prove it”. So I put together some backup capacity numbers for storing data on tape (non-compressed and compressed) versus… Read more »
What does that really mean? When I worked for Veritas, back in 1998 we acquired a company based out of Canada called TeleBackup that backed up desktop / laptops. In 1999 Veritas acquired Seagate and the Backup Exec product which also had a desktop / laptop option. These products were meant to eventually be integrated into the main backup applications but never were. Additionally, a lot of that software was given away (hard to make… Read more »
