Not really tested commandline. The error appears constantly after approx 
75 minutes of backing up. Haven't tried yet.

In fact it is a directory, not a file. Cannot see anything unusual. It 
is a directory containing a subdirectory and some text files.
On my backupdisk (ext4) 40% is used of 2TB, I've recently done a fsck -c 
which did not reveal any problems. No lost inodes etc, or badblocks.

I'm not certain about this. The original files can be accessed and 
opened without any trouble. However on the backup they are somewhat 
skewed... The directory

/var/lib/backuppc/pc/xxx.xxx.xxx.xxx/new/f%2f/fhome/fmike/fwerk/fsystem/fTransformer/fandroid-sdk-linux/fadd-ons/faddon-google_tv_addon-google_inc_-12/fi

in fact  should be

/var/lib/backuppc/pc/xxx.xxx.xxx.xxx/new/f%2f/fhome/fmike/fwerk/fsystem/fTransformer/fandroid-sdk-linux/fadd-ons/faddon-google_tv_addon-google_inc_-12/fimages

There seems to be a limit on the record length. All records are cut off 
at the same length....
