ESX backups fail with error message failed to upload /tmp/.vzbin/packages.contents.linux24.tar.gz to host.
ESX versions prior to 3.5 Update 5 are not listed as supported Virtualization Platform Components in the Version Support Guide. This guide can be found on the portal at http://portal.vizioncore.com on the Guides/Policies tab.
Check to make sure that sftp is configured on your ESX server
1. Open an SSH session to the ESX server and login as root
2. Change directory to /etc/ssh
3. Run the following command: cat sshd_config
4. Check to see if the following line is the sshd_config:
Subsystem sftp /usr/libexec/openssh/sftp-server
If that line is not in the sshd_config file, please add it, and then restart the sshd service
service sshd restart
Also, check to make sure that there is enough space available on the ESX service console
1. Open an SSH session to the ESX server and login as root
2. Run the following command: df -h
The upload needs at least 5 MB of available space on the root partition (/)
