Scheduled task types

This section describes the available scheduled task types, as well as guidelines and requirements for each task.

Backup

Purpose: Back up managed devices.

Guidelines and restrictions:

Supported devices: Some devices, such as devices in the public cloud, cannot be backed up.
Simultaneous backups: Back up no more than 20 devices per task. Do not schedule multiple backup tasks for the same time; start with 30 minutes between backups.

Download CRL

The system automatically schedules daily certificate revocation list (CRL) updates with a Download CRL task when you configure user or audit log certificates in the system configuration. Use the scheduler to change the update interval or run a one-time update.

Download, Push, or Install Latest Update

Purpose: Schedule and install VDB updates. You do not need to push VDB updates to devices; the push task is only for software updates (which are no longer supported in the scheduler).

Note	Use Administration > Upgrades & updates > Product Upgrades to upgrade software. Scheduled software upgrades are not supported, although the web interface allows configuration.

Queue Intrusion Policy Apply

Purpose: Deploy intrusion policy changes from the Cloud-Delivered Firewall Management Center to managed devices.

Options:

Intrusion Policy: The policy you want to deploy.
Device: The device where you want to deploy the policy.

Guidelines and restrictions:

Traffic interruption: When you deploy, resource demands may result in a small number of packets dropping without inspection. Additionally, deploying some configurations restarts the Snort process, which interrupts traffic inspection. Whether traffic drops during this interruption or passes without further inspection depends on how the target device handles traffic. Refer to Snort restart traffic behavior and Configurations that restart the snort process when deployed or activated.

Update URL Filtering Database

Purpose: Obtain the latest URL filtering data from Cisco. By default, when you enable URL filtering, automatic updates are enabled. However, if you need to control exactly when these updates occur, use the scheduler.

Guidelines and restrictions:

Prerequisites: You must enable URL filtering to schedule this task. Disable automatic updates on Integrations > Cloud Services.
Update size and duration: Daily updates are typically small. With longer intervals, expect larger downloads and additional time for the changes to propagate.
