decompression error

Bad enough that my old cloud backups are now useless, I've been trying to upload new backup sets.

First set I'm trying to upload is about 40gb. This is a multi-day upload for me and I need to suspend the task once in a while for various reasons.

Sometimes I've been able to resume the backup, other times I get a yellow warning at the top : ! Decompression Error.

Once I get that error, that upload is useless. Multiple retrys (upwards of 50 times) always result in the error, so I have to delete the partial upload and start again.

I've been through this more than once now, and I have yet to get this 40gb backup done, this is getting a little ridiculous.

Icing on the cake: I click on the "More details" link, and I get an Acronis page saying "There is no information about this error available now."
