And my pg_xlog can not copy to D:/3SDATABACKUP/PITR/WAL from 06/01/2011. How
to fix error ? Please help me

Here is my Archive
# - Archiving -

archive_mode = on # allows archiving to be done
# (change requires restart)
archive_command = 'copy %p D:/3SDATABACKUP/PITR/WAL/%f' # command to
use to archive a logfile segment

Thanks in advance
