Hello to all Gentoo-users,

i want to switch to a new kernel on my server. I switch from 4.19.97-gentoo to the lastest 5.7.8-gentoo, because i need some new driver for my dvb-card.
This works without a problem. On my server i use Acronis Cyber Backup to backup complete machine to the cloud from HostEurope.

I downloaded the lastest version from Acronis Cyber Backup and installed it.

Code: Select all

wget -O /tmp/Backup_Agent_for_Linux_x86_64.bin "https://eu2-cloud.acronis.com/bc/api/ams/links/agents/redirect?language=multi&system=linux&architecture=64&productType=enterprise"

Unfortunately, the required SNAPAPI module no longer compiles

Code: Select all

Has anyone found a solution or has the same problem?

Thanks

Hello NelvinBHV.

I do not know this backup software so my first question is: Is there a need to use this software? Since a basic backup of a system could be done with basic tools you propably already have installed.

Hello Banana,

yes this software have to be used. I pick HostEurope Cloud Backup because they have to limit for just 10€ per month.
The only way is to use Acronis Cloud Backup. The backup agent installed without an error, but the need snapapi module fails every time.

Did you do a system update, or literally just update the kernel? Did sys-kernel/linux-headers get updated as well?

i.e. Can you describe how you did this bit:

I switch from 4.19.97-gentoo to the latest 5.7.8-gentoo,

If you did do a proper update, I'd say the Acronis Forums are a better place to ask your question - you're a customer of theirs after all.

Probably software is tested only with long term support kernel, try with 5.4.x version (if have support for your device)
