In this article, we will learn how to restore a file system from a snapshot in Dell PowerStore using PowerStore Manager. Before proceeding with this operation, we must ensure that the file system is offline to protect it from data corruption issues.
Table of Contents
A restore operation reverts a parent resource dataset to a previous point-in-time when a snapshot was taken. Only snapshots directly taken of the resource can be used as the source for the restore operation.
NOTE: Restore from snapshot procedure restores storage resource/file system to a previous point in time. This may lead to data loss hence careful planning is required. If only a small subset of the storage resource needs to be restored. Then we can create a thin clone from the snapshot and copy the missing data from the thin clone to the concerned storage resource.
