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:
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:
|
Decimal Value |
Binary Bit Mask |

2, 3, and 6 |
| 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.
Specifies the directory where to search for the backup file.
Note: @AlterDIr replaced @SearchAlternateBackupDirectory in LiteSpeed 8.6. Support for the old @SearchAlternateBackupDirectory parameter will be gradually phased out.
Appends data to an existing full backup file.This argument accepts one of the following values:
The @AWSUseReducedRedundancy argument specifies the use of reduced redundancy storage in Amazon S3. This argument accepts one of the following values:
|
Note: This @AWSUseReducedRedundancy argument is replaced with the @CloudStorageClass = 'rrs' argument. |
The @AWSUseServerSideEncryption argument enables the encryption of data stored at rest in Amazon S3. This argument accepts one of the following values:
The @AzureBlobType argument specifies the types of blobs that can be stored in the Microsoft Azure cloud storage. This argument accepts one of the following values: "Block", "Page".

This argument accepts variables. For more information, see LiteSpeed Variables.
Specifies the number of SQL Server buffers available for a LiteSpeed operation. The default value is set by SQL Server.
Checks if the expected full backup exists when backing up to separate files and returns a failure message if it is not found. If the full backup file does not exist, it performs a full backup. If the full backup file does exist, the decision to perform a new full or a differential backup will depend on other conditions specified. Accepts the following values:
The @CloudAccessKey argument specifies the name of the unique Cloud Web Service alphanumeric access key that identifies each user. The selections include Amazon Access Key, Azure Account Name, Google e-mail styled account, S3 Compatible Storage Access Key.
The @CloudAccessKeyEnc argument specifies the name of the encrypted unique Cloud Web Service alphanumeric access key that identifies each user.
This parameter enables automatic file striping for LiteSpeed cloud backups.
This parameter contains the stripe size in GBs. LiteSpeed logic uses the database size to make a decision about the number of stripes needed for LiteSpeed cloud backups. For example, if you have a database with a size of 200GB and set @CloudAutoStripingThreshold = 50, then LiteSpeed uses 200/50 = 4 stripes.
The @CloudBucketName argument specifies the name of the container for cloud objects. Bucket names must be at least 3 and no more than 63 characters long. The selections are Amazon Bucket Name, Azure Container Name, Google Bucket Name, Google Bucket Name requirements are described at https://cloud.google.com/storage/docs/naming, S3 Compatible Storage Bucket Name,
The @CloudGovRegion argument enables a special restricted region for the US Government use in Amazon S3 and Azure Clouds. This argument accepts one of the following values:
The @CloudParallelUpload argument, parallel parts transfers, is used to create fast uploads to the Azure Cloud or Amazon S3. The default number of parallel uploads:
The @CloudPartSize argument determines the size of each part that is uploaded to the cloud. The default part size:

For Amazon S3:
RRS: Reduced Redundancy Storage - for non-critical data considering lower level of redundancy rather than Standard storage.
|
Important: : In versions less than 8.5 you should use --AWSStorageClass. The @AWSStorageClass argument is no longer valid in subsequent LiteSpeed versions after 8.5. |
For Google Storage:
The @CloudVendor argument specifies the name of the cloud service provider. The argument accepts one of the following values: "AmazonS3", "AzureBlob", "GoogleStorage" or "S3Compatible".

Note: Delete backups is not supported in Maintenance Plans with this option.
Appends a user comment to the backup.
This argument accepts variables. For more information, see LiteSpeed Variables.
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.
Works in conjunction with the @encryptionkey parameter.
Specify the encryption level. Higher levels improve security, but they require more CPU and take longer. Test Optimal Backup Settings on analyzing the best backup settings for your environment.
This argument accepts one of the following values:

Specifies the minimum number of days since last full backup required to perform full backup. The default value is 14.
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'
Name of database(s) to exclude from this backup.
If @ExcludeDatabase is supplied as a variable, this name can be specified either as a string constant (@ExcludeDatabase = database name) or as a variable of character string data type, except for the ntext or text data types.
Tip: The @ExcludeDatabase argument can be applied together with @MultiDatabaseType to exclude several databases from the process.

2—Long erase / write new header
3—Low level controller format / write new header
NOTE: Any successful format operation (values 1, 2, and 3; not all are available to all drive types) lays down a LiteSpeed tape header that will identify this tape as containing LiteSpeed backups. Using @init=1 (or -I in the command line) will not lay down a tape header.
This option causes LiteSpeed to issue a full backup, if one of the following problems is discovered in the current backup set:
NOTE: If a problem is detected and a full backup is created through escalation, an error will be returned.
This argument accepts one of the following values:
DEPRECATED LiteSpeed 8.8: Was used to store for the Google Cloud Storage project ID; the project ID is now obtained from login. This parameter is retained for compatibility with old backup/restore scripts.
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'.

1—AboveNormal
2—High
The @ProxyHost argument is optional and specifies the name of the proxy host name that is running the proxy server.
|
note: If the @ProxyHost 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. |
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. |
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. |
The @ProxyPasswordEnc argument is optional and specifies the encrypted proxy server password credential.
|
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. |
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. |
Specifies a partial backup, which includes all the read/write files in a database: the primary filegroup, any read/write secondary filegroups, and any specified read-only files or filegroups. If the database is read-only, @read_write_filegroups includes only the primary filegroup.
Specifies a number of days to retain the backup. LiteSpeed will not overwrite this file for this number of days.
Specifies days of the week when a full backup is never performed. It accepts the following formats:
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.
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.
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.
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)
Specifies how long to wait for a TSM device.
DSMI_DIR path if needed.
DSMI_LOG path.
Specifies the TSM file space, the logical space on the TSM server. It can be the drive label name or UNC name. You can supply multiple instances of this argument.
NOTE: IBM recommends that an application client should select a unique file space; it is recommended that LiteSpeed users follow this practice with a specific file space reserved for LiteSpeed backups.

NOTES:
Name of database to be backed up or restored.
This parameter specifies a database:
to be backed up (xp_backup_database and xp_slsFastCompression)
containing the transaction log to be backed up (xp_backup_log)
to be restored (xp_restore_database and xp_restore_log)
on which you wish to check the progress of an activity (xp_slsReadProgress)
for which you want to delete old backups (xp_slsSmartCleanup)
If supplied as a variable (@database), this name can be specified either as a string constant (@database = database name) or as a variable of character string data type, except for the ntext or text data types.
Specifies the destination where to delete files from. Possible values: All, Disk, TSM, Tape, Cloud.
Displays backups that are to be removed (delete candidates) or kept according to the specified conditions and SmartCleanup logic. SmartCleanup does not remove any backups, if this parameter is specified.
