I have a small multisite installation with 3 websites (one small gaming group profile site, a blank wordpress theme and a small multisite hub theme installed into the root site.
From the WPMU website I was prompted to run my first backup. It took me to my sites admin page and I set a schedule. I then decided to do a manual backup while I was there.
Hours later and the backup is still in progress (currently on step 86). The last step took about 4 minutes.
The problem is that the website is completely unresponsive until the end of each step. So users have to wait 4 minutes to load a page, for hours at a time, every time I backup.
Is there something wrong here?
