Settings

The Configuration Manager Settings Screen is used to set the backup retention policy and the amount of space that must be available on the CMM before an upgrade is allowed.

Backup Retention Policy

These settings are used to specification of a maximum number of days and a minimum number of backups to keep per device.

• Minimum Backups - The minimum number of backups you want to retain per switch. (Range = 1 - 365, Default = 365)
• Maximum Days - The maximum number of days that you want to retain those backups. (Range = 1 - 365, Default = 365)

If a backup for a switch is older than the maximum number of days, and the total number of backups is at least the minimum number specified, older backups will be deleted in accordance with the retention policy. The backup retention policy is applied when a new backup is successfully created.

For example, Let ‘b’ denote the minimum number of backups to retain, ‘d’ the retention period in days, and ‘n’ the number of backups that are less than ‘d’ days old. For each device, the larger of the two numbers, ‘b’ and ‘n’, shall be retained. If  'b' = 3 and 'd' = 60 days:

• Switch 1: There are 6 backups, 4 of them are more than 60 days old, 2 other builds are less than 60 days old: => 3 backups will be retained.
• Switch 2: There are 6 backups, 1 of them is more than 60 days old, 5 other builds are less than 60 days old: => 5 backups will be retained.
