hard disk space, you can choose to delete files that have been included in previous
backups.

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

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

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