Problem
amdump(8) fails with sendbackup error "no backup size line" for a DLE.
| ? gtar: /var/lib/amanda/gnutar-lists/machinename_home_src_1.new: Missing record terminator | ? gtar: Error is not recoverable: exiting now | sendbackup: error [no backup size line]
Check sendbackup debug logs on the Amanda client. It is usually in /tmp/amanda/client/<amanda configuration>/ directory.
Explanation
- /var filesystem on Amanda client does not have free space
- GNU tar state file /var/lib/amanda/gnutar-lists/machinename_home_src_1.new is corrupted.
- If you are using GNU Tar 1.16, this can be caused by GNU Tar bug #18487.
- Trivial problem: The directory which should be backedup does not exist anymore
Solution
- Create more space in /var filesystem if needed.
- Force a full backup for the DLE to rewrite the state file.
- Upgrade/downgrade to a working version of tar
- For trivial problem: Remove or change directory in disklist file
