Acronis 2018 "The last backup has failed..."

Thread needs solution

Hi All,

My Acronis Backup was working perfectly until I upgraded the motherboard BIOS. I upgraded Windows 10 too and some applications and I wanted to make new full backup of the boot drive. It did not work. It gives me following error message "The last backup has failed. The backup cannot be started.Plug in external drive containing the files of this backup." The strange thing I do not use USB drive for backup. The boot drive is raid array of two M2 SSDs on the motherboard (Gigabyte Aorus X570 Master) and the destination drive is sata hard drive raid array. I created Acronys system image but it turned out that zip file is 11.6MB so I can not upload it. Please help.

Slobodan, welcome to these public User Forums.

If you have changed BIOS and Windows etc, then I would recommend creating a new backup task and reselect the Source and Destination again in the new task.

I am assuming that you have already tried reselecting the Source and Destination for the existing task that is giving the error message.
