This is just an FYI, something I encountered after working on this issue all day. It appears that Ubuntu 20.04.3 installs the 5.8 kernel. Once this happens, Veeam Agent for Linux 5.0 will no longer work. I kept getting this in my logs:
[error] Failed to perform backup
[error] Server error 301: Moved Permanently
[error] Processing finished with errors at 2021-11-27 00:16:32 UTC
To get around this, I uninstalled Veeam Agent 5.0 and installed 4.0. 4.0 works without an issue. Hoping to save someone else from a headache with this post.
Veeam makes great products, been using them for years, I think this is the first issue I've ever really ran into.
Hello,
and welcome to the forums and thanks for sharing a solution.
The solution sounds odd to me, but good to hear that it works for you
The kernel version I see in 20.04.3 is 5.4.0-90, but I don't have the HWE kernel package. We also have Veeam Agent for Linux 5.0.1 available since some weeks.
Sorry, I neglected to mention that this is not a Server install, but rather a Desktop install of Ubuntu. I believe the Desktop versions ship with HWE by default. We only have a very small number of Desktop Ubuntu installs, which would explain why we haven't seen this before. We are not seeing this issue anywhere else, 99% of our physical Linux machines are server versions (Fedora, CentOS, etc); the kernel numbers are all 5.4 or lower. I believe your point about HWE is spot on, the Desktop versions with the HWE kernel are pushing a later kernel version.
Thanks for the clarification, this definitely sheds a bit more light on why we were having this issue. So far, Agent 4.0 has succeeded with our file-level backups for this particular machine. We will stick with this version for the time being.
