Source folder(s)/
file(s)

This is read-only and shows the path of the source folder for backup.

Backup Target

This field is read-only and shows on which volume (whether internal or external) the 
backup files are stored. If the target location is a remote NSA, this shows the remote IP 
address.

Target Path

This field is read-only and shows the target folder for the backup files.

Compression

This field is read-only and shows whether the backup employs compression.

Compression reduces the size of the file that you want to back up. Backup is then faster, 
but restoring may be slower, so if backup space is not a concern and recovery speed is, 
then turn off compression.

Encryption

This field is read-only and shows whether the backup employs encryption.

You can have the NSA use a password to encrypt the backup files.

Bandwidth

For backups to a remote NSA, you can restrict the bandwidth to help prevent the 
backups 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.

Purge Policy

The NSA maintains the files that have been included in your backups. However to save 
hard disk space, you can choose to delete files that have been included in previous 
backups.

•

Select Keep All Old Backup files to store all files that have been included in 

previous backups.

•

If you want to store a certain number of backup files, select Keep Only the last n 

backup files (1-30). Enter a value (n) from 1 to 30 to specify how many backups 

the NSA stores. All backup files older than the last one are deleted. You will not be 

able to recover files that existed (only) in those previous backups. Select this if 

backup space is limited and recovery of old files is not important.

•

If you want to store all backups for a certain time period, select Keep Backups for 

n day(s)(1-3650). Enter a value (n) from 1 to 3650 to specify how many days the 

NSA stores all backup files. After this day has expired, all backup files will be 

deleted.
