backing up to the same drive as the DB

if your SQL Server is a VM (ran from a SAN) is there any risk in writing your backups to the same  virtual drive as the live database - or was this "best practice" more geared towards physical servers.

Not sure performance is a concern as backups are run through the night when the databases aren't really being updated by employees. I dont know whether virtual disks can go bad on themselves - or whether its more likely if there's a hardware failure at SAN level then it would affect the whole VM.

Just imagine that drive have a problem. You'll lose your database and it's backups.
NEVER store backups in the same disk where your database is.

Where I am coming from though - do/can virtual drives go wrong in isolation on SAN based VM's?

You shouldn't backup to the same SAN that you're using for datafiles.

There is an old adage that reads "The only certainties in life are death and taxes", to that you can now add HDD's failing.

No you should not store your backups on the same vs as your cm, and yes even if stored on a SAN, it can still fail although the risk should be low - but it's still a risk!
You need to evaluate all the failure scenarios and decide what failures your organisation can or cannot tolerate and put in place plans to cover those that you cannot.
I would suggest that losing your DB and its backups with a single failure is not acceptable
