Challenge

When interacting with Linux servers, Veeam Backup & Replication may encounter a “Permission Denied” error during script execution (Pre-freeze, post-thaw, and repository data mover agent scripts), even when the account being used is the root user.

Cause

All script files are uploaded to and executed from /tmp, which may be mounted with the “noexec” attribute.

Veeam uses the path /tmp to store temporary files in keeping with the Filesystem Hierarchy Standard.

Solution

If there is an entry for the mount point /tmp with the attribute noexec, the /etc/fstab will need to be edited to remove this attribute.

Execute this command:

mount | grep noexec | grep tmp

Example:

Advanced Alternate Solution

If, for security reasons, it is not feasible to disable noexec on the /tmp folder, you may create the following registry value on the Veeam Backup Server to assign a different folder to be used. This change will change the path Veeam Backup & Replication uses when communicating with all Linux servers. If you use this registry setting, you must ensure that the folder path specified in the registry value exists on every Linux server that Veeam will communicate with. If not, some tasks/jobs will failExamples:
• Oracle Guest Processing
• Pre-Freeze/Post-Thaw Scripts
• File Level Restore as they will not attempt to create the folder path.
