Sorry for this really basic question
but how much free disk space is required to decompress the backup and restore it over an existing database?
The error I'm getting:
10/18/2012 10:20:13 AM: Failed to read backup file header: Failed to write data block size of 65536 from 2293760 (wrote 0): There is not enough space on the disk Failed to write data block size of 2293760 (wrote 327680)
I'm trying to take the back-up of our production database and restore it over the previous night's copy on a reporting server. The MDF file is about 425 GB and there only 287 GB free.
Does there need to be >425 GB free? So does the total size of the drive need to be MDF size * 2?

Or does the space need to be on the drive the .SQB file is on? (the MDF is on G and the backup file is on H and neither have a spare 425GB...)
