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

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
