The system administrator is typically responsible for:
- Physical integrity of the server
- Operating system and ancillary programs maintenance and upgrades
- Adding and deleting user accounts and password management, unless the accounts are maintained on a Windows NT / 2000 / 2003 primary domain controller or a Unix NIS server.
- Backup and restore. This is typically done with a commercial backup product, such as Veritas BackupExec or CA Arcserve (more details).
