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.
