Zimbra slow down everyday at 3:30

[wooo]

May I ask what is zimbra doing every night around 3.30 AM?
At that time mailboxd is using lot of CPU.

Thank you

I guess it could be a backup routine?
Have a look at the zimbra crontab

sudo crontab -l -u zimbra

and if the server does anything else other than just run Zimbra, it could be something there
