The cause of this is usually a slow client host which has to compress a large disk. If compression takes a long time, the server does not receive any data from the client and generates a "data timeout".

Template:Troubleshooting Explanation The cause of this is usually a slow client host which has to compress a large disk. If compression takes a long time, the server does not receive any data from the client and generates a "data timeout".

Template:Troubleshooting Solution You can try one of these:

  • Disable compression on the failing DLE (by putting compress none in disklist file)
  • Use 'fast' rather than 'best' compression (by putting compress client fast in disklist file)
  • Compress data on the tape host (by putting compress server fast or compress server best in disklist file).
  • Increase the dtimeout parameter in amanda.conf
