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 connectionís
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.
