I would advise you split this into different hosts, where each host
has only aa-az or ba-bz etc ...
This way, when a share fails to backup for some reason, only a small
portion of the overall backup will fail instead of the whole lot.
Use ClientNameAlias (from memory) to point hostname-a, hostname-b,
hostname-c, etc to hostname.
Also check your number of concurrent backups is low, you don't want
multiple backups to the same 'host' at the same time. Some people have
written scripts which will check this and cause the backup to fail for
the current backup attempt if there is already a backup running. (See
the archives/google with keywords concurrent, lock, backup, etc or ask
and someone might have a better pointer).

Adam
