deduplication cache. If any repeated strings are found in the repository, that data is replaced with references to the data, which
saves storage space in the repository. This is sometimes referred to as off-line deduplication, since this deduplication process
occurs upon your request, instead of incrementally as snapshot data is transferred.
The optimization process is processor-intensive. The amount of time it takes to run this job depends on several factors. These
factors include the size of your repository; the amount of data in your repository; available network bandwidth; and existing load
on the input and output of your system. The more data in your repository, the longer this job runs.
The following actions are superseded or canceled when the Repository Optimization Job is occurring.
● Delete Recovery Points Job
● Maintain Repository Job
● Check Repository Integrity Job

For steps on optimizing an existing DVM repository, see Optimizing a DVM repository on page 68.
You can interrupt the repository optimization job for a limited time if required. For more information, see Interrupting or
Resuming the Repository Optimization Job on page 68.
Optimizing a DVM repository
You must have a DVM repostiory in your Core to perform this procedure.
You can perform offline deduplication of data saved to an existing DVM repository. This is accomplished by launching the
Repository Optimization Job.
NOTE:
Dell recommends performing the Optimize Repository job only after increasing your deduplication cache size. This
action lets you reclaim repository space and more effectively use the DVM deduplication cache.
Complete the steps in this procedure to optimize a DVM repository.
1. Navigate to the Rapid Recovery Core Console.
2. On the icon bar, click (More ), and then select Repositories.
The Repositories page appears.
3. In the DVM Repositories pane, from the row representing the repository you want to optimize, click and then select
Perform Optimization Job.
A warning prompt appears asking you to confirm the optimization.
4. Click to confirm the optimization.
The optimization job takes precedence over most other jobs. If necessary, you can interrupt an optimization job in progress.
For more information on interrupting or resuming this job, see Interrupting or Resuming the Repository Optimization Job on
page 68.
Interrupting or Resuming the Repository Optimization Job
When you initiate the Optimize Repository Job, the selected DVM repository is deduplicated. This deduplication optimization is a
processor-intensive job intended to save space in the repository. For more information, see About the Repository Optimization
Job on page 67.
Once this job has been initiated, you can interrupt the job using the following procedure. This pauses deduplication. If you have
already interrupted a optimization, you can resume the process using this procedure.
NOTE: This procedure applies only to DVM repositories and only when the repository optimization job has been initiated.
Complete the steps in this procedure to interrupt or resume a repository optimization job.
