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.
