Configuring backup copies

You can specify the maximum number of backup versions of configuration and index files kept in the primary location.

For example, assume the backup count is set to 5 and the configuration file is called xyz.cfg. When a save command is executed, the file xyz.cfg is saved with a .1 extension. Each subsequent backup increments the numeric extension until the maximum count is reached. The oldest file is deleted as more recent files are saved. For the example with a count of 5, the files are:

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 SF/CPMSF/CPM is performed for all configurations and their associated persistent index files. Use the following command to configure the maximum number of backup versions:

Example: MD-CLI

configure system management-interface configuration-save configuration-backups

Example: classic CLI
```
configure system config-backup
```
