Specifies to store the backup as a TSM archive. This argument accepts one of the following values:
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.
Specifies the TSM client owner user password. Not required, if specified in the options file or if backing up with the Passwordaccess Generate option.
Specifies the TSM configuration file.
You can use the %TSMDEFAULTPATH% variable to make LiteSpeed detect the default TSM configuration file path automatically (by getting from LiteSpeed defaults as a priority or the registry - HKEY_LOCAL_MACHINE\SOFTWARE\IBM\ADSM\CurrentVersion\BackupClient)
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.
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.
NOTE: If the backup was a striped backup and the point-in-times of the various striped files are different (rare but can be different a second or so), then the most recent of the times must be chosen.
0 (success) or non-zero (failure).

The procedure encrypts a password into a value for @jobp, that is suitable for xp_backup_database and xp_backup_log procedures as an encrypted key.
EXEC master.dbo.xp_encrypt_backup_key
@key ='Mypassword'

Processor affinity designates specific processors to run LiteSpeed, while not allowing LiteSpeed to run on the remaining processors.
This argument accepts decimal values and hexadecimal values. If a value begins with "0x" it is interpreted as hexadecimal. A positive 64-bit integer value translates to a binary mask where a value of 1 designates the corresponding processor to be able to run the LiteSpeed process.
NOTE: 32-bit Windows is internally limited to a 32-bit mask.
For example, you need to select processors 2, 3, and 6 for use with LiteSpeed. Number the bits from the right to left. The rightmost bit represents the first processor. Set the second, third, and sixth bits to 1 and all other bits to 0. The result is binary 100110, which is decimal 38 or hexadecimal 0x26. Review the following for additional information:
|

| 205 | 11001101 | 1, 3, 4, 7, and 8 |
Tip: Before you start tuning the CPU Throttle or Affinity parameters to adjust backup performance, try limiting the number of threads. If you decide to use an affinity value other than default, it is recommended that you limit the threading as well. You may also want to consider using Adaptive Compression to maintain backup performance. For more information, see Adaptive Compression.
The name of the LiteSpeed backup device file to be extracted. This argument accepts network destinations.
For TSM backups and TSM archives, this argument accepts the following formats:
tsmbkp:<filespace>\<high>\<low>
You can supply multiple instances of this argument.
Specifies the particular backup to use when recasting, restoring, extracting or reading from files with multiple appended backups. You can run xp_restore_headeronly to query the files contained within the backup set given by backup_file_name.
The smallest chunk of memory LiteSpeed attempts to write to disk at any given time.
Value used to generate the encryption key for the encryption algorithm. If you do not supply encryption key, then the program will not encrypt the backup. If you use the wrong encryption key, the restore will fail.
Caution: When encrypting data, take care not to lose the encryption key; a backup cannot be restored or recovered without the original encryption key.
Example of key: 'Mypassword'
Specifies a backup location (e.g. C:\backups\AdventureWorks.bak). This argument accepts network destinations. You can supply multiple instances of this argument to use stripe backups.
Disk restores:
Specifies the particular backup to use when recasting, restoring, extracting or reading from files with multiple appended backups. You can run xp_restore_headeronly to query the files contained within the backup set given by backup_file_name.
Tape restores:
Identifies the backup set to be restored. For example, a file number of 1 indicates the first backup set on the backup medium, and a file number of 2 indicates the second backup set.
Disk or TSM backups
Tape backups
See also @format.
NOTE: 0 is the default value if you do not provide this parameter.
Specifies if LiteSpeed should wait and retry the read or write operation on failure. You can define retry options using the following parameters:
Note: This functionality is only available for disk and cloud operations.
Writes a log file for the operation. This argument accepts one of the following values:
0—Logging off.
1 or any odd value—Logging on. Log file is removed on success.
2 or any even value—Logging on.
The default output directory is C:\Documents and Settings\All Users\Application Data\Quest Software\LiteSpeed\SQL Server\Logs (or C:\ProgramData\Quest Software\LiteSpeed\SQL Server\Logs) (or C:\ProgramData\Quest Software\LiteSpeed\SQL Server\Logs). To log to a different directory add @Trace='logpath=path'.
See Configure Logging in LiteSpeed for information about LiteSpeed logging.
Specifies the largest unit of transfer in bytes to be used between SQL Server and LiteSpeed. The possible values are multiples of 65536 bytes (64 KB) ranging up to 4,194,304 bytes (4 MB). The default is 1048576 (1 MB).
Specify the location and name of the Microsoft Tape Format (MSTF) base file.
The extractor utility will create one backup device file for each thread used in a LiteSpeed backup.
The extracted files containing the native SQL Server backup will have the following format: base_file_namex.
Where:
x is a number or letter that represents the sequence of the files. In case there are no additional files, the base file will not have an x appended to its name.
NoteS:
You only need to specify this parameter once. The extraction utility will create all the necessary files automatically.
If a full path is not specified, the extracted files will be created in the current directory.
Specifies the priority of the LiteSpeed process compared to other processes running on the same server. This argument accepts one of the following values:
-1—Below Normal
0—Normal (Default)
1—AboveNormal
2—High
Displays the syntax summary of the LiteSpeed command-line utility.
Specifies the maximum CPU usage allowed. The argument accepts an integer value between 1 and 100. The default value is 100. This is the percentage of the total amount of CPU usage (across all enabled processors) available.
Used by LiteSpeed to activate trace logging.
Specifies to store the backup as a TSM archive. This argument accepts one of the following values:
Specifies the TSM file.
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.
Specifies the TSM client owner user password. Not required, if specified in the options file or if backing up with the Passwordaccess Generate option.
Specifies the TSM configuration file.
Specifies how long to wait for a TSM device.
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.
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.
NOTE: If the backup was a striped backup and the point-in-times of the various striped files are different (rare but can be different a second or so), then the most recent of the times must be chosen.
