DB Backup on a compressed drive

Is this a good idea to use compressed drive (Windows NTFS compression) for D
B
backup files?
What is the common practice and what are the risks?
Thanks,

Personally, I prefer not to use compressed drives for backup. I prefer
using a commercial SQL backup compression tool. This decreases the time to
get the data out of SQL, thus minimizing the impact on the host system.
Since I also prefer backing up directly to a network file share, this has
the additional benefit of reducing the network traffic.

From the article:
"Performing SQL Server database backups to disk files on compressed volumes
is also not recommended. The failure modes are still under investigation,
but some evidence indicates that this backup is less reliable than backing
up to regular non-compressed volumes. If backups to compressed volumes are
performed, a complete DBCC should be run before each backup and after each
restore. The time required to run the DBCC should be factored into the
decision to use this backup technique. "
