WORKAROUND:
1. The Extraction Utility may be able to return the file to a native format, which would be restored via the native SQL Server process.
For additional detail, see Solution:
https://support.quest.com/SUPPORT/index?page=solution&id=SOL148912. Verify the backup file using the following script:
EXEC master.dbo.xp_restore_verifyonly
@filename = 'C:\Program Files\Microsoft SQL Server\MSSQL\BACKUP\northwind.bak', @logging=2
/*
@filename = { 'backup_file_name' | @backup_file_name_var }[,...n]
[, @filenumber = { file_number | @file_number_var }]
[, @encryptionkey = { 'encryption_key' | @encryption_key_var }]
[, @logging = { 0 | 1 | 2 | @logging_var}]
*/
RESOLUTION:
None.
