My previous post showed how to setup a new DD appliance and integrate with Veeam using DD Boost see here
Now to show the juicy results. In my setup I have three Veeam servers backing up to local disk as a tier 1 repository then a Backup Copy job to the DD2500 for long term tier 2 retention. My tests were to compare using DD Boost with the recommended settings compared to without and comparing backing up directly to the DD2500.
Test 1 - Standard Veeam settings
Backup Job to Tier 1. Job settings below. Results 482GB processed in 55:36 @ 126MB/s overall
- Veeam in-line dedupe - enabled
- Veeam compression - extreme
- Storage optimization - local target 1MB
Copy Job to Tier 2. Job settings below. Results 358GB processed in 43:03 @ 191MB/s overall
- Veeam in-line dedupe - enabled
- Veeam compression - Auto (keeps existing compression)
Test 2 - Veeam recommended settings for DD Boost (see here)
Backup Job to Tier 1. Job settings below. Results 482GB processed in 37:01 @ 216MB/s overall
- Veeam in-line dedupe - disabled
- Veeam compression - optimal
- Storage optimization - local target (16TB +backup files) 8MB
Copy Job to Tier 2. Job settings below. Results 363.9GB processed in 39:31 @ 230MB/s overall
- Veeam in-line dedupe - disabled
- Veeam compression - Auto (keeps existing compression)
Test 3 - Direct to DD
Backup Job direct to the DD using Veeams recommended settings. Job settings below. Results 462.7GB processed in 1:15:17 @ 97MB/s overall
- Veeam in-line dedupe - disabled
- Veeam compression - optimal
- Storage optimization - local target (16TB +backup files) 8MB
Conclusion
As you can see using Veeam’s recommended settings the overall processing for tier 1 and tier 2 is just short of 50% quicker. I end up with a slightly larger footprint on tier 1 but a smaller backup window. By using DD Boost as a tier 2 copy job I have less impact on the production environment and by using copy jobs but also have an efficient data transport to the DD by only sending unique data. Finally by using a dedupe appliance I have some fantastic long term capacity and dedupe rates.
One of the key benifits when using DD Boost is the time savings when taking a synthetic full. Below are the results, the difference is incredible
- Without DD Boost - synthetic full takes 37:47
- With DD Boost - synthetic full takes 05:05!!
