Hi Heri

The following error concerns a file in a folder which is maintained by rdiff-backup itself. I never changed something therein. rdiff-backup cannot recover itself. Each run of

rdiff-backup" --include-globbing-filelist rdiff_include_f_to_r.txt F:/Daten R:/Daten

ends up with this error.

What can I do in order to fix this?

Txs in advance.

Copy from console (first three lines were written by my starter batch):

Previous backup seems to have failed, regressing destination now.

I have not heard of this type of error before so I would tentatively suggest that it is not the fault of rdiff-backup but some other problem (filesystem corruption maybe?).

If this file is really missing and it is the *only* thing wrong with the repository, you might be able to fix it just by recreating it (as it was a nul file anyway) on the destination (this is for Windows command prompt, with Linux or Cygwin you can use touch): <nul (set/p z=) >"R:/Daten/rdiff-backup-data/increments/SW/Projekte/Sandpiper/Polyright/eclipseWorkspace/.metadata/.plugins/org.springsource.ide.eclipse.commons.gettingstarted/dashboard/141530009687411/common/bootstrap/js/bootstrap-datetimepicker.2015-04-04T13;05828;05807+02;05800.missing"

Another possible clause of your difficulty, more intractable, is that the path+name length for this 'missing' file is 272 characters - you may be coming up against the 260 character limit for Windows paths - see http://stackoverflow.com/questions/1880321/why-does-the-260-character-path-length-limit-exist-in-windows. I don't of a way around this one except to say 'rdiff-backup *from* Windows yes, but always rdiff-backup *to* Linux', which is probably not much help in your situation. You could try physically mounting your R: drive on a Linux system, copy the whole repo onto a Linux-based filesystem (e.g. ext4), and then try doing a remote backup from the Windows machine to the new repo on the Linux machine.
