LiteSpeed for SQL Server 8.9.5 - Installation Guide

Script Maintenance Plans Tasks

You can perform various database maintenance tasks from the command line. To use the SLSSQLMaint utility, change the directory until you are in the directory containing slssqlmaint.exe. (Usually, C:\Program Files\Microsoft SQL Server\MSSQL10.SQL2008\MSSQL\Binn).

NOTE: You can generate scripts by opening tasks in the LiteSpeed UI Console and clicking View T-SQL. About Creating Maintenance Plans

Arguments

-Argument

Description

-AdaptiveCompression <value>

Automatically selects the optimal compression level based on CPU usage or Disk IO. For more information, see Compression Methods.

You can tell Adaptive Compression to optimize backups either for size or for speed. This argument accepts one of the following values:

  • Size
  • Speed
-AFFINITY <mask>

Specifies the affinity mask for the process. The mask is a 64-bit integer value. By default, it is 0 and will utilize all CPUs.

For more information, see Processor Affinity.

-AltBkpDir <path> Specifies the directory where to search for the backup file.

-Attached <file_or_directory>

Specifies filepaths to include in both backup and restore operations. The filepath can be either a single file or a directory. If it is a directory, then LiteSpeed recursively includes all files and subdirectories. All attached files are encrypted and compressed, with all pertinent backup parameters supported. This feature works for disk, tape, TSM, and Double Click Restore as well. You can supply multiple instances of this argument.

When used within the context of a restore operation, the path parameter can be expanded to include a new destination. This form will take the syntax of <file_path> to <new_file_path>. The new filepath can be used to specify a new location but cannot rename a file.

This argument only restores the attached files. It does not restore the database, just the files that were attached to that backup.

NOTES:

  • The original entire directory path need not be supplied (e.g. c: to c:\testadSattsm is allowed).
  • c:\testad to testadr would restore all files in directory c:\testad to c:\testadr.
-BackupEsc

This option causes LiteSpeed to issue a full backup, if one of the following problems is discovered in the current backup set:

  • The full backup is missing.
  • A differential backup is missing from the backup set (excludes backups automatically removed after the specified retention period).
  • LSN verification fails in the backup set.
  • Verify operation fails on full or differential backup.

NOTE: If a problem is detected and a full backup is created through escalation, an error will be returned.

-BackupKey <encryption_password>

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'

-BkExt <extension> Specifies the extension of the backup files.
-BkFileName Specifies that each path specified includes the filename.
-BkUpDB

Specifies the database backup type.

-BkUpLog Specifies the tlog backup type.
-BkUpMedia <value>

Specifies the backup destination. This argument accepts one of the following values:

  • DISK
  • TAPE
  • TSM
  • TSMArchive
-BUFFERCOUNT

Specifies the number of SQL Server buffers available for a LiteSpeed operation. The default value is set by SQL Server.

-CkDB

Checks the allocation and structural integrity of tables and indexes.

-CkDBNoIdx Checks the allocation and structural integrity of tables.
-CleanHis <values>

Enables the Cleanup History task. This argument accepts one or more of the following:

  • <number><time_unit>—Removes historical data older than specified time period. You can use one of the following time units:
    • HOURS
    • DAYS
    • WEEKS
    • MONTHS
    • YEARS
  • BKUP—Deletes back up and restore history.
  • JBS—Deletes SQL Server Agent jobs history.
  • MAINTPLN—Deletes Maintenance plans history.
  • Activity—Deletes LiteSpeed activity from the Local Repository.
  • CentralActivity—Deletes LiteSpeed activity from the Central Repository.
  • PurgeInfo—Deletes any information for deleted databases.
  • LogShipping—Deletes log shipping history.
  • Status—Deletes status history (Job, DTS, Maint Plans).
  • ShrinkLog—Shrinks the repository databases log files.
-COMMENT <comment>

Appends a user comment to the backup.

This argument accepts variables. For more information, see LiteSpeed Variables.

-COMPRESSIONLEVEL <value>

Specifies the compression level for the backup. Valid values are 0 through 8. 0 bypasses the compression routines. The remaining values of 1 through 8 specify compression with increasingly aggressive computation. 2 is the default value for disk backups and 7 is the default value for cloud backups.

When choosing a compression level, it is best to try various options using your equipment and data to determine the best option for your environment. Use the Backup Analyzer to test the performance of different compression levels. For more information, see Test Optimal Backup Settings.

NOTE: If both the compression level and Adaptive Compression option are passed in, LiteSpeed will not error out and will select and use Adaptive Compression.

-CrBkSubDir

Creates a subdirectory for each database.

-CRYPTLEVEL <value>

Specifies the encryption level. This argument accepts one of the following values:

  • 0—40-bit RC2

  • 1—56 bit RC2

Accepted values are 1-99, the default value is 35.

-SmartDiff <number>DAYS

Specifies the minimum number of days since last full backup required to perform full backup. The default value is 14.

-T Uses a trusted connection (to the server) instead of requiring a password.
-THREADS <number_of_threads>

Determines the number of threads used for the backup. You will achieve the best results by specifying multiple threads, but the exact value depends on several factors including: processors available, affinity setting, compression level, encryption settings, IO device speed, and SQL Server responsiveness. The default is n-1 threads, where n is the number of processors.

-THROTTLE <value>

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.
