Issue

The backup starts normally but the following message shows up in the report:

 myhost.com /disk1 lev 0 FAILED [data timeout]


Diagnose

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".

Solutions

  1. Disable compression on the failing DLE (by putting compress none in disklist file)
  2. Use the fast instead of best compression (by putting compress client fast in disklist file)
  3. Compress data on the tape host (by putting compress server fast or compress server best in disklist file).
  4. Increase the dtimeout parameter in amanda.conf
