How To Perform a Full Destructive Restore of an EMC Device Using an NDMP Option Backup
Perform full destructive restore:
When performing a full destructive restore, the NVB feature requires the target file system
be of equal size or greater than the file system backed up.
When you use the backup image created by using NVB to perform a full destructive restore,
the restore occurs at the volume level. Large sequential writes are issued to the volume as
data blocks are read from tape and written directly to the specified volume. All existing data
on the target file system is destroyed. This type of restore ensures the best possible data
block write performance.
1. Create a RAWFS volume of equal or greater size than the file system that was backed up.
2. Create a new Restore job:
-Select the Restore Selection at the Top level (Date of backup level).
-Choose redirect restore. Manually type the path to the RAWFS file system as browsing to a RAWFS file system is not possible (e.g. \\VNXDevice.domain:10000\\raw-fs-vol-name)
NOTE: You will need to have two backslashes \\ between the device name and the RAWFS volume.
-Ensure Restore over existing is selected.
3. Run the Restore.
