Which operations are supported for managing snapshots in PowerFlex? (Choose two).

Dell PowerFlex provides robust snapshot management capabilities. A primary function is the ability to restore a volume to a previous point-in-time using a snapshot, which overwrites the source volume's data. This is a fundamental data recovery operation. Additionally, PowerFlex enables the automation of data protection through "Snapshot Policies." These policies allow administrators to define schedules for the automatic creation and retention of snapshots for specified volumes or consistency groups, ensuring regular, hands-off data protection.

B. Convert snapshots to writable volumes: This is incorrect. PowerFlex allows creating a new, independent, writable volume from a snapshot (a clone), but the snapshot itself remains a read-only, point-in-time object and is not "converted."
C. Deduplicate snapshot data: This is not a user-managed operation in PowerFlex. While PowerFlex supports data reduction features like compression, it does not provide a specific function to deduplicate existing snapshot data on demand.

1. Dell PowerFlex Administration Guide (Version 4.0):

For Answer A (Restore): In the section "Snapshots

" the operation "Restore Volume from Snapshot" is detailed. It states

"You can restore a volume from a snapshot. This operation overwrites the data on the source volume with the data from the selected snapshot." (Page 119)

For Answer D (Schedule): The section "Snapshot policies" explains their function: "A snapshot policy defines a set of rules for automatically creating and retaining snapshots of a storage entity... You can define a policy to create snapshots every few minutes

hours

or days." (Page 122)

For Incorrect Option B: The guide describes the "Create a volume from a snapshot" operation

clarifying that "The new volume is a writable

thinly provisioned volume

" which is distinct from converting the original snapshot. (Page 120)

2. Dell PowerFlex: Concepts and Architecture Guide (Version 4.0):

For Answer D (Schedule): This guide reinforces the concept of scheduled snapshots under the "Snapshots" section

mentioning

"Snapshot policies can be defined to automate the creation and deletion of snapshots." (Page 36)

For Answer A (Restore): The guide describes the purpose of snapshots for recovery: "Snapshots enable you to perform backups and restores of volumes." (Page 35)
