hi,
I'v try to make a base backup use pg_start_backup, pg_stop_backup and
rsync, but failed.
After run select pg_start_backup('label') on db server, I run rsync on
backup server, and got some errors like 'file has vanished: xxxx', think
this should be ok since it's documented in the manual. Then run select
pg_stop_backup() to end the backup.
But when I try to use this backup to restore to a specific time on backup
server, got errors bellow:

We do this base backup everyday, and the error occur sometimes, not always
happen. I think it's must something wrong in our operations, anyone know
why this happen? May be we should not use rsync or there is something
impotent we missed ?
