Data timeout



This article is a part of the Troubleshooting collection.

Problem

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

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

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".

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
