Deduplication and Replication
Lets take a look at how the systems behave, and see what the consequences are.
First, some background and assumptions. All numbers are real, achievable, and realistic in normal backup environments:
- In-line deduplication is 1.44 TB/hr over IP (true for both the DL3D 3000 and the DD690)
- Scheduled deduplication is 2.5 TB/hr over FC (for the DL3D 3000)
- IP replication runs at 250 GB/hr (this is really bound by link speed, latency, and so on, so I have chosen a modest figure representative of a single Gigabit IP link with low-ish latency)
In addition to this, to clarify the terms: Read the rest of this entry »
Fun With Tape, Part 2!
A fun little video from the good guys in marketing at EMC. I now have definitive proof that there are at least two of them with a sense of humor. Who’d have thunk?
It is just a little riff on the whole “I’m a Mac… And I’m a PC!” thing, involving disk with deduplication and tape. Enjoy.
Backup and Recovery Webinars
Thought a few people might be interested in these. Yes I am advertising. But I am advertising for knowledge. This is all good stuff if you need to worry about VMware or bare metal recovery. If you don’t? Nothing to see here, move along…
The sessions are:
Thursday, September 18, 2008 – 3:00 pm ET. How to implement a complete solution to quickly recover from server hardware failures.
2) Best Practices for Backup and De-duplication in a VMware Environment
Thursday, Sept 24th, 2008 – 3:00 pm ET. With VMware Consolidated Backup (VCB) and EMC Avamar de-duplication, EMC provides leading-edge backup methodologies for virtual environments. Backup that reduces bandwidth contention, improves availability of CPU and memory resources, performs faster backups, and saves you time and money. EMC Avamar quickly and efficiently protects virtual machines with global data de-duplication technology.
3) The Ideal Solution for Protecting Physical and Virtual Environments.
Thursday, October 9, 2008 – 3:00 pm ET. How to optimize your backup system by Integrating deduplication into your VMware environment.
