Acronis backup failed because snapAPI kernel module is not loaded for kernel
Issue
We get the following error when using Acronis to backup a Linux server (old Centos 6.10 using extended support)
Backup failed because snapAPI kernel module is not loaded for kernel '2.6.32-754.35.8.el6.x86_64'.
Solution
Take a backup or snapshot on the server.
Run these altered commands on the affected device:
service acronis_mms stop
find /lib/modules/$(uname -r)/ -name snapapi26* | xargs rm -rf
find /lib/modules/$(uname -r)/ -name snumbd26 | xargs rm -rf
rm -rf /var/lib/dkms
dkms ldtarball --force --archive /usr/lib/Acronis/kernel_modules/snapapi26-0.8.48-all.tar.gz
dkms install -m snapapi26 -v 0.8.48
service acronis_mms start
Once the above commands are run, please check if the snapapi26 module is loaded by running the command:
modprobe snapapi26
echo $?
A 0 echoed is a success.
Finally, run the backup manually from the cyber protection console, and check if it is succeeding.
