A redirected restore of SQL fails with an error indicating there is not enough free space, even though there is plenty of disk space in the target location.
V-79-65323-3257 - There is insufficient free space on disk volume 'C:\' to create the database. The database requires 'n' additional free bytes, while only 'n' bytes are available.
If the backup came from a virtual machine and granular / GRT selections are being restored from tape, the error could be referring to the staging location.
When performing a GRT restore from a sequential device such as tape, it is required to stage the information on a local disk first, then the required file is extracted from the staged copy on local disk and restored.
Change the staging location as instructed in the following articles:
