Hi,
There are no specific best practices/advantages for backing up to disk it is the same as backing up to a tape.
The advantages of backing up to disk are:-
Backups and restores are faster than from a tape.
No specific hardware changes are required for backup and restores.
Additionally refer this:
- Defrag the Server Partitions
- Monitor the network for physical problems (Use management utilities for
managed network equipment, Network monitor, Protocol analyzer, Event
Viewer, etc.)
- Do not use AOFO for database backups like Exchange and SQL.
Additionally refer these technotes:
