LiteSpeed for SQL Server 8.9.8 - Security and Compliance Guide

xp_restore_database

Restores LiteSpeed full and partial backups created with LiteSpeed. Files and filegroups may also be restored either from a file or filegroup LiteSpeed backup operation, or from a full database backup operation using xp_backup_database. When restoring files or filegroups, you must apply a transaction log using xp_restore_log. In addition, file differential backups can be restored after a full file restore using LiteSpeed.

NOTE: A database cannot be restored unless the restore process has exclusive access to the database. No user connections can exist when performing a database restore.

xp_restore_database (restore partial backup - filegroup offline)

NOTE: The following example shows the syntax for performing partial restores using the “read_write_filegroups” parameter. The database used in the example below, FGBackups_PROD, contains the following filegroups: Primary, FG1. FG2, and FG3).

Tip: The read only filegroup FG3 is offline after the restore is complete as indicated in the following example.

EXEC master.dbo.xp_restore_database

@database = 'Prod_test' ,

@read_write_filegroups = 1,

@filename = N'I:\FGBackups_FULL.bkp',

@with = N'REPLACE'

xp_restore_database (restore partial backup - filegroup online)

Tip: To restore the read only filegroup FG3 and bring it online after the partial restore above has completed, a full backup containing the filegroup must be used for the restore as indicated in the following example.

EXEC master.dbo.xp_restore_database

@database = 'Prod_test'

, @filegroup = 'FG3'

, @filename = N'I:\FGBackups_FULL_keep.bak',

@with = N'REPLACE'

xp_restore_database (restore fast compression partial backup - offline)

NOTE: The read only file group, FG3, is offline after the restore is complete.

EXEC master.dbo.xp_restore_database

@database = 'Prod_test',

@read_write_filegroups = 1,

@filename = 'I:\SQLbackups\FGBackups_PROD.litespeed.f0.bkp' ,

@with = N'REPLACE'

xp_restore_database (restore fast compression partial backup - online)

Tip: To restore the read only file group, FG3, and bring it online after the partial restore above has completed, a full backup containing the filegroup must be used for the restore.

EXEC master.dbo.xp_restore_database

@database = 'Prod_test'

, @filegroup = 'FG3'

, @filename = N'I:\FGBackups_FULL.bak',

@with = N'REPLACE'

xp_restore_database (restore partial differential backup)

NOTE: The read only file group FG3 is offline after the restore is complete.

It is a two-step process to restore a LiteSpeed partial full backup followed by a restore of a LiteSpeed partial differential backup. Both steps are needed in order to restore a partial differential backup and bring the database online.

Step 1 - restore the LiteSpeed partial full backup

EXEC.master.dbo.xp_restore_database

@database = 'FGBackups_PROD' ,

@read_write_filegroups = 1,

@WITH = 'PARTIAL' ,

@filename = N'I:\FGBackups_FULL.bkp',

@with = N'REPLACE',

@with = N'NORECOVERY'

Step 2 -restore the LiteSpeed partial differential backup

EXEC master.dbo.xp_restore_database

@database = 'FGBackups_PROD' ,

@read_write_filegroups = 1,

@filename = N'I:\FGBackups_FULL_diff.bkp',

Tip: To restore the read only file group FG3 and bring it online after the partial restore above is completed, a full backup containing the file group must be used for the restore.

EXEC.master.dbo.xp_restore_database

@database = 'FGBackups_PROD'

, @filegroup = 'FG3'

, @filename = N'I:\FGBackups_FULL_keep.bak',

@with = N'REPLACE'

Arguments

Tips:

• To see the list of accepted arguments and data types for arguments, execute the following:
  exec master.dbo.<procedure_name> show_help

• To convert the script for use with the command-line utilities, execute the following:
  exec master.dbo.<procedure_name> show_cmd, <xp_arguments>

@affinity

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, an incoming 64-bit mask will be truncated to 32-bit.

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:

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.

@attachedfile

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.

Note: Delete backups is not supported in Maintenance Plans with this option.

@database

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)

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.

@DisconnectUsers

Disconnect users on executing restore (in standby mode only). This argument accepts one of the following values:

• 0—Do not disconnect users (default).
• 1—Disconnect users.

@encryptionkey

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'

@file

Specifies a logical database file used for file or filegroup backups. You can supply multiple instances of this argument.

@filegroup

Specifies a database filegroup to include in the backup or restore. You can supply multiple instances of this argument.

A filegroup backup is a single backup of all files in the filegroup and is equivalent to explicitly listing all files in the filegroup when creating the backup. Files in a filegroup backup can be restored individually or as a group.

@filename

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.

@filenumber

Type: Integer

Disk restores:

Specifies the particular backup to use when recasting, restoring, extracting or reading from files with multiple appended backups. A backup file can contain multiple backups. Each time you append a new backup, a sequential number is assigned to this backup within the backup file. 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.

@ioflag

Specifies if LiteSpeed should wait and retry the read or write operation on failure. You can define retry options using the following parameters:

• DISK_RETRY_COUNT—Specifies the number of times that a specific operation will be retried on failure. The default is 4 retries, the maximum allowed setting is 1000.
• DISK_RETRY_WAIT—Specifies the number of seconds to wait immediately following a failure before retrying. The default is 15 seconds, the maximum allowed setting is 300.

NOTE: This functionality is only available for disk and cloud operations.

For example, to specify a database backup where each failure can be retried once after a 30-second wait:

EXEC master.dbo.xp_backup_database
@filename='c:\test.bkp'
, @database='test'
, @ioflag='DISK_RETRY_COUNT=1'
, @ioflag='DISK_RETRY_WAIT=30'

Network Resilience

@jobp

Specifies an encrypted key. (Similar to @EncryptionKey).

You can use xp_encrypt_backup_key to convert the password (encryption_key) for use with @jobp. The original password (or encrypted key generated by xp_encrypt_restore_key) must be used to restore a backup.

@logging

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.

@maxtransfersize

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).

@Page

Type: Varchar

The @Page argument allows you to restore one or more damaged pages without the need to restore the whole database. Restoring and recovering a few individual pages might be faster than a file restore by reducing the amount of data that is offline during a restore operation. However, if you have to restore more than a few pages in a file, it may be more efficient to restore the whole file. For example, if lots of pages on a device indicate a pending device failure, consider restoring the file, possibly to another location, and repairing the device. Please refer to the Microsoft SQL Server documentation on Restore Pages for additional information and guidelines on page restores.

@ProxyHost

Type: Varchar

The @ProxyHost argument is optional and specifies the name of the proxy host name that is running the proxy server.

@ProxyLogin

Type: Varchar

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

@ProxyPassword

Type: Varchar

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

@ProxyPasswordEnc

Type: Varchar

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

@ProxyPort

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

@read_write_filegroup

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.

@restoreascompressed

Works in conjunction with @restoreasreadonly, creates a folder if it does not exist, and then compresses it. This argument accepts one of the following values:

• 0—False (default)
• 1—True

@restoreasreadonly

Instructs the restore operation to leave the database in read-only mode. This argument accepts one of the following values:

• 0—False (default)
• 1—True

Using this option, you can restore a user database into an NTFS compressed folder or restore a tlog to a read-only database in a compressed folder.

NOTES:

• When using an NTFS-compressed folder for a database, it can only be restored as read-only.
• You can only use this feature on Windows NTFS file systems.

@returndetails

Generates a single-row result set.

• 0—False (default)
• 1—True

The result set contains the following details:

• Pages (total data + log if we have it)
• Speed (MB/Sec)

Tip: In Toad, you can use Group Execute to produce a single result set for several server instances.

@rewind

Type: Integer

Applies only to backing up and restoring tape. This argument accepts one of the following values:

• 0—Leave the tape unwound (default)

• 1—Rewind the tape after writing/reading

@throttle

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.

@tsmarchive

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

• 0—False (default)
• 1—True

@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.

@tsmconfigfile

Specifies the TSM configuration file.

@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.

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.

@unload

Type: Integer

Applies to tape backups and restores. This argument accepts one of the following values:

• 0—Keep tape loaded (default)

• 1—Unload and eject tape from the drive after operation

@UseSSL

The @UseSSL argument specifies that the connection uses SSL security. This argument accepts one of the following values:

• 0—Do not use SSL
• 1—Use SSL (default)

@with

Type: Varchar

Each @with argument should be a syntactically complete and correct statement. Please refer to the SQL Server Transact-SQL backup and restore documentation for the syntax and usage.

The supported formats are:

• @with='PARAMETER'
• @with='PARAMETER=''accepted_value'''

NOTES:

• Extended stored procedure arguments are limited to 255 characters. If you need more than 255 characters, use multiple @with arguments.
• Do not supply the @with parameter if no additional features are required.

This extended stored procedure accepts the following @with parameters:

@NoOutput

Disable output information for the procedure

1. 0 - Output information enabled (default).
