Error in archiving

I have been using your plug-in for a couple of years on three or four WP installations on different servers and it has worked smoothly on all of them until recently. In the last few weeks I have had a similar problem to some other users here, at the archiving stage, but only on my biggest site (still not huge – hundreds of KB, not hundreds of MB).
Here’s the report:

I’m looking forward to a solution because it’s not good to have to rely on a single copy of my work.

Thanks,
