Performance Tuning SQL Server Backup and Restore

SQL Server backup and restore performance is often a greater issue than many DBAs realize. This is because the time it takes to backup and restore a database plays a very large part in how large a single SQL Server database can be. For example, if it takes more than 24 hours to backup or restore a database, obviously this presents some problems.
What can sometimes happen to the DBA is that a database may be of reasonable size now, given their current server hardware, and backups and restores may take a reasonable amount of time. But as time goes by, the database grows, and at some point the amount of time to backup and restore the database becomes too long given the backup and restore window available. The moral to this story, keep a close eye on backup and restore times, and factor this in when projecting future hardware needs for your SQL Server databases. [6.5, 7.0, 2000, 2005]
