Hi

If speed is the issue, then use the right tools, right?

Research VDI. In my experience writing from VDI device connected to a seperate server hosting the backup file was 80% faster than not using VDI.

Keep an eye on the log files. When the db is restored, and it's created as the default size, when the restore happens and you have a 100GB log file the OS will create a file sized 100GB and format it to be available for the database.

Better ways?
