Thank you, I use rsync to backup every day, so I lost a day of data.

If you've already run -delete (-move is a better choice if you know DN
fault is temporary), then the missing blocks are already deleted from
the namespace permanently. No way to recover the data since the blocks
have also been invalidated by now.
A HDFS Snapshots feature will arrive in near future to cover the
backup scenarios that may prove useful in cases such as this.
