I've also been thinking it would be nice to make such a thing more
readily available. Currently I just sopranocmd export to a file which is
itself incrementally backed up by bacula. But having some sort of rdiff
like thing build into the backup process would make sense.

For redland, a scheduled repair and lzo db_dump -p of the db files seems
to work OK.

cd /where-the-redland-store-is
for if in *.db
  echo "Fixing: $if"
  db_dump -r $if >| dump
  rm -f $if
  db_load -f dump $if
  rm -f dump

# lzop expansion will be faster than importing...
for if in *.db; 
  db_dump -p $if | lzop > $BACKUPDIR/$if.dump.lzop;
