Hello there,

 I have a problem with the amanda backup.

Amanda is totally stop working after I amflush all the logfiles in
/usr/am_dump.

When I execute amcleanup, the messages shown as below:
amcleanup: no unprocessed logfile to clean up.
Scanning /usr/am_dump...

When I execute amcheck, here is the message:

Tape fs3_3 label ok <----***I have put this tape on Wednesday and this is
still OK on Friday!!!***
Server check took 3.831 seconds

Amanda Backup Client Hosts Check

When I execute amrecover, here is the message:

Then I setdisk to /vol0, the error message is:

I have no idea what is going with Amanda, please help.

Please find an attachment of amanda.conf file.  Would you please advise
where is it gone wrong?

I am using amanda version 2.4.2p2.

Thanks very much for your help.
