LiteSpeed for SQL Server 8.9.8 - Security and Compliance Guide

xp_restore_headeronly

Retrieves the backup header information for all LiteSpeed backups on a particular LiteSpeed backup device. The header information is sent as a row by the server for each backup on a given backup device in a table.

Tip: To retrieve information from TSM backups, also use xp_view_tsmcontents.

@Logging

Writes a log file for the operation. This argument accepts one of the following values:

• 0—Logging off.

   , @CloudAccessKey = N'***' -- my key
   , @CloudSecretKey = ***' -- my key
   , @CloudRegionName = N'us-west-2' -- us-east-1, us-west-2, us-west-1, eu-west-1, ap-southeast-1, ap-southeast-2, ap-northeast-1, sa-east-1
   (this is an optional parameter. Region for selected @CloudBucketName will be used.)

Results

xp_restore_headeronly displays the following information:

Returns

0 (success) or non-zero (failure). Message indicating success or failure of the operation. Return codes represent the native error number returned from SQL Server for any errors encountered during the operation. Result codes returned from the LiteSpeed utilities are added 50000 to keep them separate from the SQL Server code range.

To capture the output message, run the following:

declare @rmsg varchar(999)
exec master..<procedure_name> <arguments>, @resultmsg=@rmsg output
select @rmsg

To capture the output message and the result code, run the following:

declare @rc int
declare @rmsg varchar(999)
exec master..<procedure_name> <arguments>, @resultmsg=@rmsg output, @resultcode=@rc output
select @rc, @rmsg
