The Myths about Compression and Data Deduplication

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 »

How Much Backup Capacity Does Deduplication Really Save?

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 »

Enterprise Data Protection at the Edge

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 »

Comprehensive Capacity Optimization - Deduplication 2.0

Technology is great isn't it? When someone thinks they have a new idea on the same old technology foundation they call it "X 2.0". I have been watching the banter between analysts and vendors (specifically NTAP’s Dr. Dedupe and Permabit’s CEO Tom Cook) on the topic of Deduplication 2.0 and it is my belief that the proverbial boat is being missed (since we are using water analogies). I have been watching these guys hash it… Read more »

The Side Effects of Backup on Server Virtualization

Server virtualization has changed the IT landscape dramatically. It has become a magic potion curing a number of ills in the physical server world such as low individual CPU utilization and excess use of space, power and cooling in the data center. However, like all potions that cure what ails you, there can be side effects. You need to be careful of what the Witch Doctor orders.

When I speak with customers who have aggressively… Read more »
