#04175281 Backup fails due to certificate/no valid private key

[adexl]

Dear community, I try to backup a v-server from Strato which is running Debian. Veeam Agent was installed successfully and a rescan operation from the Veeam Backup Console works fine. But when doing a backup the operation fails with the following error message:

Error: Failed to execute agent management command startBackup. The certificate used to connect to backup server has no valid private key.

I tried to use credentials user/root and even private/public key authentication. The remote server accepts both authentication methods without any issue. Does anyone have a similar problem or even knows a solution for that? Thanks for your kind help! Alex.

Hello,
unfortunately you did not attach logs to your case and the email address also seems to have a problem as the answer from support to you returned with "(Undelivered): 550 5.2.0 No such mailbox"

the next thing you might run into is that Strato V-Servers are Virtuozzo containers. So you need to do file based backup: veeam-agent-for-linux-f41/can-val-run-i ... =Virtuozzo

I don't know how much you want to backup, but maybe it is even easier to do NAS-backup instead of agent based backup.


Best regards,
Hannes

I have the same error. Yesterday, I have upgraded 4 veeam Agents for Linux to Version 4.
Ubuntu 14.04 and Ubuntu 16.04

Solution was to recreate veeam agent config DB and rescan the agent from VBR Console.

1) Stop the service:
# systemctl stop veeamservice
2) Make database backup:
# mv /var/lib/veeam/veeam_db.sqlite /var/lib/veeam/veeam_db.sqlite.bak
3) Start the service:
# systemctl start veeamservice
4) Wait a few minutes for the database to rebuild
5) Rescan machine in the protection group
