Problem: On SME Server the HAL Daemon often not recognize a USB Stick or Disk which you can use for “Console” Backup Program. Solution: – Create a Script with #nano /root/backup.sh – insert: service haldaemon restart service messagebus restart console exit This restart the HAL Environment before Console (SSH-Admin-Tool)is opened. To prevent Users to write on the Shares if you run the Backup you can add: service haldaemon restart service messagebus restart service smb stop console service smb start exit This will stop Samba-Windows Shares! and prevent File-Access-Lockwaits!
