Hello,
OK, thanks, I've got the regressions running on a different machine with a
newer kernel now, and the segfaults have gone away.
I ran virtual-backup-test, and it told me that it completed OK.
However, I was suspicious, so I watched carefully what it was doing.
It looks to me as if it is doing exactly what I was seeing with my original
setup, where the VirtualFull only includes the previous Full and misses out
the differentials and incrementals.
To prove this, I made a couple of changes to virtual-backup-test (the patch
is attached to this email). I also made sure that 'Accurate = yes' was set
on the backup job definitions in the bacula-dir.conf, but I don't think that
matters.
Before the first full backup, I echoed the date to a file in the area that
that gets backed up. Then I echoed the (new) date to the same file just before
the last incremental backup.
I would then expect the restore before and after the subsequent VirtualFull
to give the same results, but they don't.
The test reports the following:
!!!!! virtual-backup-test failed!!! 11:27:21 !!!!!
!!!!! Restored files differ !!!!!
Status: backup=0 restore=0 diff=1
Graham.
