Use this screen to specify compression, encryption and purge policies for the
backup job. This step is only available if you are doing an archive backup or a
synchronization backup to a remote target.

The following table describes the labels in this screen.

LABEL DESCRIPTION
Compression Select Yes if you want NSA to compress the files for your backup.
Otherwise, choose No.
In an Archive backup, compression is a method of packing
computing files in a way that saves hard disk space.
For a Synchronization backup (to a remote target), the source data
will be compressed before the transmission to reduce the
transmission time. It is used in slow networks only.
Encryption Select Yes if you want NSA to encrypt the files for your backup.
Otherwise, choose No.
In an Archive backup, this means using a password to secure files.
For a Synchronization backup (to a remote target), this means
securing the file transfer session. However the final file stored on the
remote NSA is unencrypted. This takes a long time. Make sure you
really need this feature before enabling it.
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.
