Object Level Recovery can restore tables using two different internal techniques to handle the record inserts. The first and default method uses BCP files and a TSQL BULK INSERT statement. Object Level Recovery will write a BCP format file and an accompanying binary data file to the local file system. These files may become very large depending on the table size and will require permissions to write to a temporary directory. The default TEMP location can be set by using the @TempDirectory parameter or by setting a permanent temp location in the LiteSpeed configuration file. An alternate insertion method can be specified to use Sql Server’s Sql Native Client capabilities. This method inserts row-data directly into the destination database bypassing any storage on the local file-system. To enable this method, use the parameter @backend='SQLNativeClient' (or -b 1 from the command line). To make this the default method set the value “BackEnd=SQLNativeClient” in the Object Level Recovery section of the LiteSpeed configuration file. Regardless of the insertion method used, the batch size can be globally managed by setting the value “BulkImportBatchSize=<N>”. This will set the number of row inserts for each batched transaction. | |||
|
-C <object_name> |
--CreateScript |
Specifies the name of the object to recover. | |||
|
-d |
--RestoreAsOnDiskTable |
This option allows you to restore an in-memory table as a regular table. | |||
|
-D <diff_backup_filename> |
--DifferentialBackupFileName |
Name of backup file to restore. Used for differential backups instead of full backup files. You can supply multiple instances of this argument. | |||
|
-E <destination_server_name> |
--DestinationServer |
Name of the destination server. | |||
|
-F <full_backup_filename> |
--FullBackupFilename |
Location and name of the backup file device containing the object to recover. Examples: UNC Path: \\servername\share\path\filename Local path: c:\filedirectory\filename NOTE: There can be multiple files but they must be listed in the order in which they were backed up. | |||
|
-G <filegroup_name> |
--OnFileGroup |
Destination ON filegroup name. | |||
| -g <log_filename> | --LogBackupFileName |
Specifies location and name of the log backup file. You can supply multiple instances of this argument. | |||
|
-H <script_text> |
--ScriptText |
SELECT Script literal text. For more information, see Supported SELECT Statements. | |||
| -h <striped_logfilename> | --LogBackupStripeFileName |
Specifies the striped log file name. NOTE: The striped files for a given log backup must be specified before the next log backup set is specified. | |||
| -i <table_objects> | --IncludeTableObjects |
Type:String Instructs LiteSpeed to script or recover one or more of the following:
The value is a list of options, separated with commas. | |||
|
-I <filegroup_name> |
--TextImageOnFileGroup |
Destination TEXTIMAGE_ON filegroup name. Used to restore a BLOB (binary large object). | |||
|
-J <filename> |
--ResultsFileName |
Name of comma separated file (.csv) that is generated instead restoring into a database. This is an ad hoc solution for users want to see the restored data in Excel. You can only use this argument for text data. | |||
|
-k |
--KeepComputedColumns |
Instructs LiteSpeed to keep the computed columns with the object restore. This argument accepts one of the following values:
| |||
|
-K <encryption_key> |
--Key |
Type: Varchar 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' | |||
|
-l |
--LSMPath |
Specify a custom path for finding or creating the LSM file. | |||
|
-L <option> |
--LSM |
Specifies handling for OLR LSM mapfile(s).
| |||
|
-M |
--FileStreamOnFileGroup |
Specifies a file stream filegroup to include in the object restore. | |||
| -m |

| |||
|
-N <file_number> |
--FileNumber |
Specifies the particular backup to use when recasting, restoring, extracting or reading from files with multiple appended backups. | |||
|
-O <object_name> |
--RestoreTable |
Specifies the name of the object to recover. NOTE: Currently only tables. Table name must be preceded by database owner. | |||
| -p <prefix> | --PrefixTableObjects |
Adds a prefix to the names of the table's objects you selected to script or recover. | |||
|
-P <password> |
--Password |
Specifies the user password. Passwords are case-sensitive. Required if the connection type is not a trusted connection. | |||
|
-Q <script_file_name> |
--ScriptFileName |
The file name that the script is output into. When used with execute-select, this file contains the select statement(s). | |||
| -R | --Trusted |
This is Windows Authentication. | |||
| -s <suffix> | --SuffixTableObjects |
Adds a suffix to the names of the table's objects you selected to script or recover. | |||
|
-S <destination_database_name> |
--DestinationDatabase |
Specifies the destination database. | |||
|
-t |
--Trace |
Used by LiteSpeed to activate trace logging. | |||
|
-T <destination_table_name> |
--TableName |
Specifies the name of the destination table. LiteSpeed will not overwrite an existing table. If you select the same server instance and database as the original table, you must use a different table name. NOTE: For Execute-Select operations, LiteSpeed will attempt to insert (append) all selected records into existing table. | |||
|
-U <username> |
--UserName |
Specifies user login ID. Required if the connection type is not a trusted connection. Login IDs are case-sensitive. | |||
| --UDT |
Create table script:
| ||||
|
-V |
--ViewContents |
View contents. | |||
|
-W <temp_directory> |
--WriteDirectory |
Specifies a temporary directory for use with Object Level Recovery. Use this argument when the default Windows temp directory does not have enough free disk space for the restore process.
| |||
|
-X <ship_directory> |
--ShipDirectory |
Ship directory for packaging files for subsequent restore. | |||
|
-Y <object_type> |
--Type |
Specifies the type of object. If you omit this parameter the object type defaults to table, so you should use this argument to recover schema objects other than tables. This argument accepts one of the following values:
| |||
| -y | --DisableLogProcessing |
Instructs LiteSpeed to skip all transaction log backups and tail log processing. This may improve read and recovery times. | |||
|
-Z <filename> |
--ObjFileName |
Identifies a file that contains a list of objects. The format of this file is "ObjectType,ObjectName" per line. Tip: You can use -V and -Y arguments to create the objects list. |
Cloud-specific arguments work in conjunction with the LiteSpeed arguments. See Syntax and Examples for more information.
