[rdiff-backup-users] strange read-only file error

[Eric Beversluis]

I'm getting this huge set of error messages, most of which I don't
understand. There's a "read-only file system" line which seems to be
intelligible but I have no idea why it appears. I'm plugging in my
external HDD the same way I did last time, when rdiff-backup ran fine,
and the 'mount' command shows this for the backup file system,
"/dev/sdb1 on /media/b080d187-ad00-4b4a-9721-fcbe5e839827 type ext3
(rw,nosuid,nodev,uhelper=devkit)"--ie, it's presumably mounted 'rw'.

Here's the whole set of messages (I tried to run the rdiff-backup twice
and got slightly different results, but no success.) Hopefully someone
can help me on this.

Previous backup seems to have failed, regressing destination now.
Warning: Could not restore file home/eric/Eric
Jobs/11468659522-CraigsList!

A regular file was indicated by the metadata, but could not be
constructed from existing increments because last increment had type
None.  Instead of the actual file's data, an empty length file will be
created.  This error is probably caused by data loss in the
rdiff-backup destination directory, or a bug in rdiff-backup
