Purpose

This article provides an example of a granular ‘sudo’ configuration for the Linux account that Veeam Backup & Replication will use when managing a Linux-based Tape Server.

Solution

  • The Linux user account used by Veeam Backup & Replication to connect to the Linux-based Tape Server use the bash shell.
  • The Linux account must have either root or root-equivalent permissions. In the latter case, some administrators may prefer to restrict the account used by Veeam Backup & Replication to execute only a specific required list of commands as a sudoer on the target Linux machine. (See example below.)
