    Hi mac3rbi,

    Plenty of I/O would be expected, since a backup process is opening and reading every single file on your website, and then writing it out to the backup. For CPU, like any process, it'll use however much CPU is given by the webserver to it. However, UD is designed to use only one thread at a time, so if your server has multiple CPU cores, it won't use more than one. If you want to apply further limits than that, then those things would be configured at the OS level. But basically, the solution is to either make sure that your webserver has enough power to cope with a backup process, or to use the "Fix Backup Time" add-on (http://updratplus.com/shop/) to schedule your backup to run in the early hours of the night when your server will have few demands on it.

    For the PHP warnings, please send the entire log file (use pastebin.com) if necessary. I've seen this twice before, and both times it was ultimately due to an absolutely enormous database table that was having trouble backing up in the time available. I'd like to see the log to check that out.
