Restoring Data from a Snapshot
You can restore data in two ways:
• Restore individual files: Once a snapshot is created, the FluidFS cluster creates a client‐ accessible
snapshots directory containing a copy of the files included in the snapshot. Clients can easily restore
individual files from a snapshot using copy and paste, without storage administrator intervention. This
method is useful for the day‐to‐day restore actions of individual files.
• Restore a NAS Volume from a snapshot: The storage administrator can restore an entire NAS volume
where copy and paste of huge amounts of data would take significant time. This method is useful in
the case of an application error or virus attack.
Snapshots retain the same security style as the active file system. Therefore, even when using snapshots,
clients can access only their own files based on existing permissions. The data available when accessing a
specific snapshot is at the level of the specific share and its subdirectories, ensuring that users cannot
access other parts of the file system.
