I found out you can extend the timeout using this method by logging into each xcp-ng node:

Create a special file:

nano /etc/xapi.conf.d/increase-task-timeout.conf

Paste this in here: (example for 10 days)

# set XAPI task timeout to 10d
pending_task_timeout = 864000

Then, restart the stack:

xe-toolstack-restart

I have a long backup task (initial replica) where a VM has 10 2TB disks attached to it. The initial backup takes around 4 days. After a day or so, the task goes away in the task list. The backup continues. I am not sure it will complete (I am 1.5 days in). Is there some filter that is removing long tasks from the list?
