What option can a Portworx administrator use to perform snapshots of Repl 2 or 3 volumes when there is limited space on the cluster and no Object Store is configured?
Comprehensive and Detailed Explanation From Exact Extract:
Skinny Snapshots are a space-efficient snapshot technique used by Portworx for replicated volumes (Repl 2 or 3) when storage capacity is limited and no external Object Store is configured. Unlike full snapshots that duplicate data blocks, skinny snapshots capture only the differences (deltas) since the last snapshot, minimizing space consumption. This method allows administrators to take frequent snapshots without significantly impacting storage availability. Skinny Snapshots are particularly useful for on-premises environments or clusters without access to cloud object storage, balancing snapshot granularity with resource constraints. Official Portworx snapshot documentation explains how skinny snapshots work internally, improving backup and recovery capabilities under tight storage conditions without requiring cloud integration【Pure Storage Portworx Snapshot Guide†source】.
