The config-backup command allows you to specify the maximum number of backup versions of the configuration and index files kept in the primary location.
For example, assume the config-backup count is set to "5" and the configuration file is named xyz.cfg. When a save command is issued, the xyz.cfg file is saved with a .1 extension. Each subsequent config-backup command increments the numeric extension until the maximum count is reached. The oldest file ("5") is deleted as more recent files are saved.
xyz.cfg
xyz.cfg.1
xyz.cfg.2
xyz.cfg.3
xyz.cfg.4
xyz.cfg.5
xyz.ndx
Each persistent index file is updated at the same time as the associated configuration file. When the index file is updated, the save is performed to xyz.cfg and the index file is created as xyz.ndx. Synchronization between the active and standby is performed for all configurations and their associated persistent index files.
Use the following syntax to specify the maximum number of backup versions of the configuration and index files kept in the primary location.
config>system
config-backup count
The following example shows the command usage to set the maximum number of backup versions of the configuration and index files kept in the primary location to 7.
config>system#
config>system# config-backup 7
