CHAPTER 6

Storage

This chapter covers the Storage screens of the NSA.

Note: Snapshot and RAID 0 are not supported by the NSA at the time of writing (the

first release), but they are included here as they will be supported in a later

release.

6.1 Storage Introduction

Use the Storage screens to create and manage NSA internal and external volumes, disks and

snapshots

. See Section 6.3 on page 81 for more information on volumes.

6.1.1 Snapshots

A snapshot is a backup of your NSA data on the NSA. If files within a volume become

infected or corrupted, you can revert the volume back to a previous snapshot. You can

continue to work, while the snapshot is taken. It's a good idea to save your open files first

before taking a snapshot.

If a volume is restored to a previous snapshot, then ALL files in that snapshot are returned to

the state they were in at the time of the snapshot.

The NSA uses EVMS (Enterprise Volume Management System) to create snapshots.

Note: Snapshots can be used on internal volumes only.

It’s a good idea to take a snapshot of your data before you make a backup. Backups may

require several hours depending on the amount of data you have to back up. It is not possible

to run programs (like FDISK), that access the disk directly, while backup is running.

6.2 Storage Overview Screen

Click the Storage link in the Navigation panel to access the Storage > Overview screen. This

is the first screen displayed.

1. Snapshot was not available at the time of writing.
