Verify the SQL Backup file to troubleshoot the Backup Restore errors:

As mentioned earlier, the common backup restore errors and issues occur due to SQL Server corruption. To verify this, you can use RESTORE Statements - VERIFYONLY (Transact-SQL). The backup verification command checks whether the backup set is accessible. Sometimes this file can also perform additional verifications on the data to detect errors in backup file. If your backup file has some issues like corruption, then you will get errors. If it is valid, then you will get a success message. Here’s the syntax:

RESTORE VERIFYONLY

FROM <backup_device> [ ,...n ] [ WITH

{

LOADHISTORY

--Restore Operation Option

| MOVE 'logical_file_name_in_backup' TO 'operating_system_file_name'

--Backup Set Options

| FILE = { backup_set_file_number | @backup_set_file_number }

| PASSWORD = { password | @password_variable }

--Media Set Options

| MEDIANAME = { media_name | @media_name_variable }

| MEDIAPASSWORD = { mediapassword | @mediapassword_variable }

--Error Management Options

| { CHECKSUM | NO_CHECKSUM }

| { STOP_ON_ERROR | CONTINUE_AFTER_ERROR }

--Monitoring Options

| STATS [ = percentage ]

--Tape Options

| { REWIND | NOREWIND }

| { UNLOAD | NOUNLOAD }

} [ ,...n ]

] [;]

<backup_device> ::=

{

{ logical_backup_device_name |

@logical_backup_device_name_var }

| { DISK | TAPE | URL } = { 'physical_backup_device_name' |

@physical_backup_device_name_var }

}
