	LABEL	DESCRIPTION
	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.
