Avamar: How to extend the backup window beyond 16 hours using the Command-Line Interface

It is possible to set the backup window to a value greater than 16 hours using the avmaint command.

1. Log in to the Avamar Utility Node as admin.

2. Load the ssh keys per Avamar: How to Log in to an Avamar Server and Load Various Keys.

3. Optionally check the existing settings:

avmaint sched status --ava |grep -A13 "<window-param-list"

Example output:

<window-param-list
    timezone="America/Los_Angeles"
    timezone-desc="PST-08PDT+01,M3.2.0/02:00,M11.1.0/02:00">
    <window-params
      days="Sun,Mon,Tue,Wed,Thu,Fri,Sat"
      script-duration="15">
      <backup-window
        start="2100"
        duration="1200"/>
      <maintenance-window
        start="900"
        duration="1200"/>
    </window-params>
  </window-param-list>

(This output shows the backup window starts at 9pm and runs for 12 hours)

4. Run the avmaint command to update the backup window:

avmaint sched window --backup-start=<backup-window-start-time> --backup-duration=<backup-window-duration> --ava 

(Where the backup-window-start-time is the required start time of the backup window, in 24-hour format, and the backup-window-duration is the required backup window)

 The following example sets the backup window to 18 hours, starting at 8pm:

avmaint sched window --backup-start=2000 --backup-duration=1800 --ava

5. Verify that the changes have been implemented:

avmaint sched status --ava |grep -A13 "<window-param-list"

Example output:

<window-param-list
    timezone="America/Los_Angeles"
    timezone-desc="PST-08PDT+01,M3.2.0/02:00,M11.1.0/02:00">
    <window-params
      days="Sun,Mon,Tue,Wed,Thu,Fri,Sat"
      script-duration="15">
      <backup-window
        start="2000"
        duration="1800"/>
      <maintenance-window
        start="1400"
        duration="600"/>
    </window-params>

(This output confirms the backup window starts at 8pm and runs for 18 hours)
