Backup through the CLI:
1- Log into the CLI to the # prompt
2- # backup create
3- # backup view (to get the index number of the backup you created
4- # backup export <index#> ftp://ip/path
CLI backup Syntax can be found in the Webguide: CLI Syntax
Newer versions (1.5.x and later) ask for the external server credentials in separate lines after the export command is executed.
If using Management Center 1.4.x, put the username and password before the hostname with port; example below:
Management Center# backup export <index> <url>
If the username or password contain the at-sign symbol (@), MC treats the characters after the first @ as DNS name for the external server, hence the error "specified host couldn't be resolved."
