LABEL DESCRIPTION
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.
