The XtremIO X2-R array, with its Protection Copies feature provided by the XtremIO 6.x code, allows

for efficient storage management through data reduction methods like deduplication and

compression. This enables the array to store a large number of virtual copies without consuming

physical capacity equivalent to the actual data size1.

Given that the backup policy requires 500 production volumes to be backed up four times a day, we

can calculate the number of virtual copies created daily as ( 500 \times 4 = 2000 ) copies per day. The

XtremIO X2-R array supports a significant number of virtual copies, and with the data reduction

capabilities, it can store these copies for an extended period before reaching the system’s maximum

capacity.

The verified answer, according to the Official Dell XtremIO Deploy Achievement document, is that

the array can store 6 days of XtremIO Virtual Copy read-only volumes before the original backups are

deleted. This takes into account the array’s ability to efficiently manage space with the Protection

Copies feature2.
