How can I close the forum by cron job?

[محروم.كوم]

Hi all,

One of the forums I'm running has been affected several times by hackers and from now on I want to keep a good backup of everything. Because vBulletin's cron jobs scheduler is not reliable to do this by it's own (according to experienced users here in this forum) I want to use my server's cron jobs to do the backups but I need to close the forum before it starts.


How can I do this? For example, I want vBulletin to close the forum for maintenance every monday at 2:00 am and re-open it at 5:00 am so I can cron-backup the site beggining at 2:10 am the same day (it shouldn't take more than 2 hours to do it in my case).

Thanks in advance, __DEFINE_LIKE_SHARE__
