Re: [rdiff-backup-users] Missing files after rdiff-backup

        Ok.  Actually, I figured this one out.  =)  I still don't know
why those files didn't copy over, and similar files were not copied in
the new version.

        Ach, good eye.  I should have mentioned that.

        I don't know why it failed.  The error log reports lots of:

UpdateError etc/oldmaps/bkp/vol/vol0/scharp/3efa75c0 File changed from regular
file before signature

        ...types of errors.  I have stdout emailed to me [full include
below], and the interesting bit seems to be:

IOError: [Errno 2] No such file or directory:
'/backups/rdiff-backup-data/increments/scratch/1.2003-07-12T18:00:01-07:00.missing'
Exception exceptions.TypeError: "'NoneType' object is not callable" in
<bound method GzipFile.__del__ of <gzip open file
'/backups/rdiff-backup-data/error_log.2003-08-01T18:00:02-07:00.data.gz',
mode 'wb' at 0x81b2660 0x81e33c4>> ignored

        So, what does this mean?  One of the necessary files is
missing?  How can I fix that?

    WM> 3) (unrelated) I have a host of these errors when I run:

    Ben> Not sure.  Are these errors from the second session that

        Yes, these were from the session that failed.  However, I also
get them when the session does not fail.  Are they normal?

    Stelios> I have not followed the thread but one possible reason if

        Good thought, but nope, these are created on a sun solaris
system, and the timestamp shows that they haven't been changed since
before rdiff-backup started running.

        Thanks for all the help,
