Hi all:
I am using rdiff-backup version 1.2.8, which is what comes with Xubuntu
14.04.
I am running rdiff-backup on Linux in order to backup some files from a
Windows PC over the network. If a Windows application is using a file,
it often locks it, so that rdiff-backup cannot read it. This problem has
been reported before, see bug #25944 "Error if file is locked".
But whether rdiff-backup can backup the file or not is not actually the
issue I am worried about here. The problem is, when such a file fails,
the exit code is still 0. See "ListError" and "Errors 1" in the log
output below for an example of such a failure.
I would like to know if the backup has suceeded, and if a file failed, I
would say it has not. rdiff-backup's manpage about the exit status is
worded in an interesting way: "If there is an unrecoverable (critical)
error, it will be non-zero".
It would be best to mention in the manpage what rdiff-backup considers
to be a critical error. If a backup tool fails to backup a file, I would
certainly consider it a "critical error". Warnings are only warnings,
and not errors. What would be a "non-critical error" then?
If my suspicion gets confirmed, but it is too late to fix this, I would
welcome some sort of "--consider-failed-files-as-critical-error" flag.
The log mentioned above is:
