You can schedule a linux sysbackup via CLI. Element Manager only offers Call Server and PD backups that I can find....
The cli is a bit odd as I cant see how to change the frequency of the backup and when entering the scheduling it must be asking for the commencement day and then assume weekly frequency on that..
e.g.
sysbackup
Usage:
sysbackup -r|-s|-b|-c|[--help]
Options:
-r remove sysbackup task from schedule
-s show sysbackup task schedule settings
-b execute one-time backup
-c setup a backup schedule
--help
Print this help message and exit.
[admin@zzzz ~]$ sysbackup -c

2. Backup to SFTP server.
Enter your choice (q for exit): 1
Cannot find USB device.
Creation of configuration file failed. <---doh! no stick installed....try again. Mine is a CPPM Co-Res and the CF card for CS backups is not an option for linux, proabaly cause it is mounted in VXWorks.
Backup will not be created.
