The following table describes the labels in this screen.

 

External 

If there is an external USB hard drive connected to the NSA (for example 
USB1 ExtVolume 1), you can select a backup target on the external USB 
hard drive.

Compression

Compression reduces the size of the file that you want to back up 
although it also consumes more of the NSA’s CPU’s computing power. 
With compression enabled, the transfer of the backup file is faster. 
However restoring may be slower. If backup space is not a concern and 
recovery speed is, then turn off compression. If the backup target is at a 
remote site to which the NSA connects through a low bandwidth 
connection, turn on compression.

Encryption

For synchronization backups, enable encryption to use encryption while 
transferring the file. However the final file stored on the remote NSA is 
unencrypted. 
For archive backups, use encryption to create password-encrypted 
backup files. 

Bandwidth

Restrict the bandwidth of synchronization backups to help stop them from 
using all of your network connection’s available bandwidth. This is more 
important when backing up to a remote NSA or computer through the 
Internet.
