11.10.3 Backup: Step 3

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.

Figure 161 Protect > Backup: Step 3

The following table describes the labels in this screen.

Table 79 Protect > Backup: Step 3

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.
