The RESTful API method used to retrieve an existing configuration from an XtremIO system is the HTTP GET methD. This is a standard method used in RESTful APIs for retrieving resources. In the context of XtremIO, the GET method would be used to call endpoints that return information about the system’s configuration. For example, a GET request to /api/json/v2/types/clusters would retrieve information about the clusters1. The Official Dell XtremIO Deploy Achievement document will contain specific details on the API calls and should be referred to for the most accurate instructions.

The best practice for creating a snapshot of a 10-volume database and presenting them to a backup server at a scheduled time is to use a Consistency Group in conjunction with the Scheduler. This approach ensures that all volumes in the snapshot are consistent with each other, as they are taken at the same point in time. The Scheduler allows for the automation of this process, ensuring that the snapshot is created at exactly 1:00 AM without manual intervention. This method is recommended for maintaining consistency across multiple volumes, which is crucial for databases to ensure transactional integrity1.

Backup Policy and XtremIO Virtual Copy: The system administrator needs to ensure that the backup policy using XtremIO Virtual Copy (XVC) can store the required read-only copies without exceeding the storage limits.

Calculating Days of Storage:

500 production volumes are backed up 4 times a day.

Total copies created per day: 500 volumes * 4 backups/day = 2000 copies/day.

Assuming the array can store a specific number of copies before older ones are deleted, let's determine the duration:

Duration Calculation:

If the array can store copies for 5 days, it can handle: 2000 copies/day * 5 days = 10,000 copies.

Thus, the array can store the backup copies for 5 days before the original backups are deleted to make space for new ones.
