Hi,
Please copy-and-paste the whole log file – the link is towards the top of the UD page. Use pastebin.com as it’ll be too big for this forum.

Hi
I have pasted the last log file at: http://pastebin.com/8gMwXLis
Is it something to do with server settings (PHP memory limit or something?)
Many thanks if you can help!

Hi Lee,
The error given is:
Abort this run: the backup_time parameter appears to be empty (this is usually caused by resuming an already-complete backup, or by your site having a faulty object cache active (e.g. W3 Total Cache's object cache)
That means that when UpdraftPlus started up again, to resume the in-progress job (the webserver kills it off every 45 seconds to save resources, so it has to be resumed), it found no information about the in-progress job.
The cause can’t be the former (it’s not complete, so the data wasn’t deleted), so must be the latter – a faulty object cache.
The log shows that you’ve got W3 Total Cache installed. Find its setting for its object cache (one of its various caches), and turn it off. It’s faulty. The problem has been reported to them various times, but they don’t seem to care. It only affects scheduled tasks (e.g. backup jobs), so that’s why it doesn’t break more things (if it did, presumably they’d fix it!).

Hi David
Thanks for your reply. The W3 Total Cache Object cache was disabled so it can’t be that! I only really enable page cache and browser cache on my sites. I am having some problems with Plesk on my Linux VPS server at the moment and Plesk are looking into it for me. Once they have solved (hopefully) the problem I will give the backup another try.
If you have any other suggestions they would be welcomed!
Regards
Lee
Try disabling and removing W3 Total Cache entirely. 100% of times we’ve seen this error, it’s been W3TC, so I wasn’t surprised to see you’d got it installed.
I’m not saying you should remove it permanently – it’d just help to confirm whether it’s the cause or not.
