How to fix a Corrupted Time Machine Backup (Snow Leopard)

Attache to volumte that has sparsebundle for your backup.

Go to that directory. cd  \Volumes\mybackup\

hdiutil attach -nomount -readwrite -noautofsck -noverify nameofmybackup.sparsebundle

/dev/disk1              Apple_partition_scheme /dev/disk1s1            Apple_partition_map /dev/disk1s2            Apple_HFSX

The next step was run fsck_hfs on the main volume.

fsck_hfs -rf /dev/disk1s2

If you get "Resource Busy errrors"  Do this.
ps -ax |grep fsck
