For some reason the backup might fail with the following message:


Backup failed because snapAPI kernel module is not loaded for kernel '4.18.0-553.34.1.el8_10.x86_64'.



Fix this by opeing Terminal and execute:


1. /usr/sbin/dkms ldtarball --force --archive /usr/lib/Acronis/kernel_modules/snapapi26-0.8.57-all.tar.gz

2. dkms install -m snapapi26 -v 0.8.57

3. service acronis_mms restart
