    Hi, I am using the free version and have just moved hosts. The site that I am using UDP on has a lot of images and files to back up. Since it has moved, there has been no successful backup.

    I am also told by Jetpack that my site is down and I am beginning t othink that UDP is the cluprit here. I think and I do NOT know – just think) that there is a throttle on IOs and that UDP is perhaps trying to do too much with creating zips of files all on the server and it is thus breaking thresholds and then stopping for ever increasing whiles until the period is just too ong and then it gives up.

    Does this sound possible?

    Hi Andy,

    That’s not really how PHP (the programming language that WP is written in) works. Code (e.g. in WP or UpdraftPlus) knows nothing about any external limits, such as I/O limits; it merely makes requests like “give me the contents of this file”. It is up to the PHP engine itself as implemented by the host to decide how it will handle limits, how quickly or slowly to respond to a request, how to balance between different threads running on the server at the same time. If it wants to make less I/O available, it can do that – but, as I say, there’s no facility for the actual caller to say things like “hey, please use less I/O”.

    Here’s the FAQ on how to make UD run using the least resources possible: https://updraftplus.com/faqs/how-much-resources-does-updraftplus-need/

    Thanks for these tips. MOST helpful. However, I am thinking that I have fallen fould of moving to a host that imposes greater limits on IO that previous hosts. This is causing (I believe!) UDP to be stalled when these resource limits are breached.

    I will look into the options in your FAQ post above and I will look at what the option limits are.

    Many Thanks
