Synology Active Backup for Business

Before installing, enable the EPEL repository:

sudo dnf install epel-release

After installation, the synosnap kernel module was failing to load with the following errors in /var/log/messages:

systemd-modules-load[609884]: Failed to insert module 'synosnap': Invalid argument
kernel: decompression failed with status 6
systemd[1]: systemd-modules-load.service: Main process exited, code=exited, status=1/FAILURE
systemd[1]: systemd-modules-load.service: Failed with result 'exit-code'.
systemd[1]: Failed to start systemd-modules-load.service - Load Kernel Modules.

The synospan module needed to be recompressed:

cd /lib/modules/6.12.0-211.33.1.el10_2.x86_64_v2/extras
sudo unxz synosnap.ko.xz 
sudo xz --check=crc32 --lzma2=dict=1MiB -6 synosnap.ko

and then the module could be loaded with:

sudo systemctl restart systemd-modules-load.service
