John Paul,

>From the SQL Server 2000 Books Online, section "Backup Devices"
(adminsql.chm::/ad_bkprst_6hmb.htm):

"A logical backup device is an alias, or common name, used to identify the
physical backup device. The logical device name is stored permanently in the
system tables within SQL Server. The advantage of using a logical backup
device is that it can be simpler to refer to than a physical device name.
For example, a logical device name could be Accounting_Backup, but the
physical device would be C:\Backups\Accounting\Full.bak."

>From where are you getting the terminology "logical backup"?
