The following table describes the labels in this screen.
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.
