Data Deduplication in the Backup World
|
| Abstract |
Deduplication is a popular topic in the industry because of the potential for cost reduction and increased efficiencies. Implementing any deduplication technology has major implications for scale, performance, and functionality.
This session is the first in a series and will focus on the specifics of data deduplication utilizing backup use cases. We will include highlights of what happens during data backup, deduplication processing, and restoration of data.

Individual Q&A recordings below:
|
|
What are the benefits of data deduplication? |
|
Are there any single points of failure that would prevent reconstruction of the information and how are these prevented in a real world deployment? |
|
Can one vendor's product read or reconstruct another vendor's deduped data? |
|
With dedup at the source, what is actually sent over the network if the data is not unique? |
|
What are the pros and cons of using dedup for file systems vs. backup and what technologies are used? |
|
Are there standards for dedup formats? |
|
Do software appliances and hardware appliances need to be from the same vendor? |
|
Is it incorrect to refer to data dedup as a form of data compression? |
|
Will any single point of failure prevent reconstruction or access and how are these issues protected in a real world situation? |
|
What is the typical level of granularity and what does it mean? |
|
Is there a diminishing return from comparing dedup data over time? |
|
Are there efforts to build tools around data that can be deduplicated and profiling tools? |
|
Dedup tools point to specific vendor's tools, which do I believe? |
|
Are there benefits to data replication in combination with dedup? |
|
How do you insure the metadata is synchronized when doing replication or any other process? |
