LiteSpeed for SQL Server 8.9.5 - Configure Log Shipping Guide

xp_restore_headeronly

Retrieves the backup header information for all LiteSpeed backups. 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.

@ProxyLogin

The @ProxyLogin argument is optional and specifies the proxy server login credential.

note: If not defined, then the LiteSpeed core engine checks the local .ini files for the proxy parameters. If the proxy parameters are not detected, then the LiteSpeed core engine connects directly to the proxy servers.

@ProxyPassword

The @ProxyPassword argument is optional and specifies the proxy server password credential.

note: If the @ProxyPassword argument is not defined, then the LiteSpeed core engine checks the local .ini files for the proxy parameters. If the proxy parameters are not detected, then the LiteSpeed core engine connects directly to the proxy servers.

note: If the @ProxyPasswordEnc argument is not defined, then the LiteSpeed core engine checks the local .ini files for the proxy parameters. If the proxy parameters are not detected, then the LiteSpeed core engine connects directly to the proxy servers.

@ProxyPort

The @ProxyPort argument is optional and contains the port number of the proxy server. The TCP/IP port values can be 1-65535.

note: If the @ProxyPort argument is not defined, then the LiteSpeed core engine checks the local .ini files for the proxy parameters. If the proxy parameters are not detected, then the LiteSpeed core engine connects directly to the proxy servers.

@tsmarchive

Specifies to store the backup as a TSM archive. This argument accepts one of the following values:

  • 0—False (default)
  • 1—True

@tsmconfigfile

Specifies the TSM configuration file.

@tsmclientnode

Specifies the TSM server LiteSpeed connects to during backups and restores. Not required, if specified in the options file or if backing up with the Passwordaccess Generate option.

@tsmclientownerpwd

Specifies the TSM client owner user password. Not required, if specified in the options file or if backing up with the Passwordaccess Generate option.

@tsmobject

Defines the TSM filespace, high level and low level. This argument accepts the following format:

tsm_filespace\tsm_high_level\tsm_low_level

where:

  • tsm_filespace is the logical space on the TSM server that contains a group of files. It can be the drive label name or UNC name.

  • tsm_high_level specifies the directory path in which the file belongs.

  • tsm_low_level specifies actual name of the file.

NOTE: You may only store one item the location specified by this argument. It is not possible to append an object to this location. You can use the -I command-line argument or @init to back up to a non-unique location.

@tsmpointintime

Specifies the date for restore/to filter results. If it is not passed, LiteSpeed will choose the most recent archived backup. The format is yyyy-mm-dd hh:mm:ss.
