Backup With Mirror

Question

Hope this is the right thread,

 

When you backup with Mirror?

 

Is that concurrent to those devices and if so, what happens if one fails does the entire backup fail?

 

Cheers,

Answer 1

A mirrored backup is basically a read once, write multiple.  So, the page is grabbed from the database and then N copies are made within your backup locations.  They either all succeed or all fail.  So, if you have a failure to one location, you will get a failure on the backup.
