One thing to keep in mind about Complete PC Backups stored on hard
disks--only the most recent backup is stored as a .vhd. The previous backups
are incremental backups stored as shadow copies. Although this helps you
save disk space, you don't have any guarantee that those previous
incrementals will be there on any given day. The oldest are purged to make
more room for newer incrementals. Increasing your storage area size would
theoretically help here (the default is 30% of the target) BUT I believe
there is a bug that causes whateever limit you set to revert back to 30%
when you take another backup. For this reason, you might want to store an
occasional Complete PC Backup on DVD, which is always a full .vhd.
To answer your question about deleting old backups--there is no graceful way
to do this short of deleting the backup folders. We've gotten lots of
feedback about this (and lots of questions).
