Hi

I am getting STRANGE reports about every other day from amanda 3.1.3


STRANGE DUMP DETAILS:

It looks like it has a problem with compressing the index. Any ideas?
Thanks

No, I do not think it is having a problem. Notice your files are named
XYZ".gz.tmp". The ".tmp" indicates it is a temporary file, possibly
existing for only a short time. In this case, when the index is
completed, the file is renamed without the ".tmp".

The message you are receiving arises because of the way tar works.
A list of files to be backed up is generated and then the backup
is done. On an active directory tree, it is not uncommon for changes
to occur between generating the list and actually backing up the
specific files in the list. Certainly, the Amanda directory tree
is "active" during an amdump run!! So such messages should be
expected. Another "strange dump" message you may see is
"file changed as we backed it up".

The message is quite disconcerting though.
Based on your analysis I intoduced a new dumptype which should exclude the
temporary index files to be backed up.

define dumptype root-tar-no-index-temp {
root-tar
program "GNUTAR"
comment "root partitions dumped with tar excluding temp files"
exclude "./etc/amanda/DailySet1/index/*/*/*.tmp"
}

I am using this dumptype now for the amanda server root partition which
holds /etc/amanda, we'll see.

Thanks
