No, but if your disk is small, starting with 5% freel might not have
been enough to hold the results of a large target so you could have
new directory entries created with no space to write or to save the
attrib files. Try going back to older versions in the archive
directory and see if the BackupPC_zcat command line tool can extract
the files.
