Paul,

Thanks for your answer.
I had a look in previous report. Last was of the 26th of April and
previous was of the 25th of April :

And this one before :

Here are they disklist conf and dumptype conf :

Why does amanda make backup if there is a zero size to dump ?

|
|
| Yes, an empty file.  Have a look at the amanda header itself too.
|
I had a look :
AMANDA: FILE 20040425 s ws/ECOLE-SQL1 lev 1 comp N program
/usr/bin/smbclient

|
|
| Not in it, it is the 46th backup image on the tape.

|
| Never seen it myself. Maybe you have more information from the
| report when the dump actually ran.  Somehow samba created 0 bytes

|
|

|
|
| "Not Applicable".  Some people say  "Not Available".
