function Backup-DbaDatabase { <# .SYNOPSIS Backup one or more SQL Sever databases from a single SQL Server SqlInstance. .DESCRIPTION Performs a backup of a specified type of 1 or more databases on a single SQL Server Instance. These backups may be Full, Differential or Transaction log backups. .PARAMETER SqlInstance The SQL Server instance hosting the databases to be backed up. .PARAMETER SqlCredential Credentials to connect to the SQL Server instance if the calling user does not have permission. .PARAMETER Database The database(s) to process. This list is auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude. This list is auto-populated from the server. .PARAMETER BackupFileName The name of the file to backup to. This is only accepted for single database backups. If no name is specified then the backup files will be named DatabaseName_yyyyMMddHHmm (i.e. "Database1_201714022131") with the appropriate extension. If the same name is used repeatedly, SQL Server will add backups to the same file at an incrementing position. SQL Server needs permissions to write to the specified location. Path names are based on the SQL Server (C:\ is the C drive on the SQL Server, not the machine running the script). Passing in NUL as the BackupFileName will backup to the NUL: device .PARAMETER TimeStampFormat By default the command timestamps backups using the format yyyyMMddHHmm. Using this parameter this can be overridden. The timestamp format should be defined using the Get-Date formats, illegal formats will cause an error to be thrown .PARAMETER BackupDirectory Path in which to place the backup files. If not specified, the backups will be placed in the default backup location for SqlInstance. If multiple paths are specified, the backups will be striped across these locations. This will overwrite the FileCount option. If the path does not exist, Sql Server will attempt to create it. Folders are created by the Sql Instance, and checks will be made for write permissions. File Names with be suffixed with x-of-y to enable identifying striped sets, where y is the number of files in the set and x ranges from 1 to y. .PARAMETER ReplaceInName If this switch is set, the following list of strings will be replaced in the BackupFileName and BackupDirectory strings: instancename - will be replaced with the instance Name servername - will be replaced with the server name dbname - will be replaced with the database name timestamp - will be replaced with the timestamp (either the default, or the format provided) backuptype - will be replaced with Full, Log or Differential as appropriate .PARAMETER CopyOnly If this switch is enabled, CopyOnly backups will be taken. By default function performs a normal backup, these backups interfere with the restore chain of the database. CopyOnly backups will not interfere with the restore chain of the database. For more details please refer to this MSDN article - https://msdn.microsoft.com/en-us/library/ms191495.aspx .PARAMETER Type The type of SQL Server backup to perform. Accepted values are "Full", "Log", "Differential", "Diff", "Database" .PARAMETER FileCount This is the number of striped copies of the backups you wish to create. This value is overwritten if you specify multiple Backup Directories. .PARAMETER CreateFolder If this switch is enabled, each database will be backed up into a separate folder on each of the paths specified by BackupDirectory. .PARAMETER CompressBackup If this switch is enabled, the function will try to perform a compressed backup if supported by the version and edition of SQL Server. Otherwise, this function will use the server(s) default setting for compression. .PARAMETER MaxTransferSize Sets the size of the unit of transfer. Values must be a multiple of 64kb. .PARAMETER Blocksize Specifies the block size to use. Must be one of 0.5KB, 1KB, 2KB, 4KB, 8KB, 16KB, 32KB or 64KB. This can be specified in bytes. Refer to https://msdn.microsoft.com/en-us/library/ms178615.aspx for more detail .PARAMETER BufferCount Number of I/O buffers to use to perform the operation. Refer to https://msdn.microsoft.com/en-us/library/ms178615.aspx for more detail .PARAMETER Checksum If this switch is enabled, the backup checksum will be calculated. .PARAMETER Verify If this switch is enabled, the backup will be verified by running a RESTORE VERIFYONLY against the SqlInstance .PARAMETER WithFormat Formats the media as the first step of the backup operation. NOTE: This will set Initialize and SkipTapeHeader to $true. .PARAMETER Initialize Initializes the media as part of the backup operation. .PARAMETER SkipTapeHeader Initializes the media as part of the backup operation. .PARAMETER InputObject Internal parameter .PARAMETER AzureBaseUrl The URL to the base container of an Azure Storage account to write backups to. If specified, the only other parameters than can be used are "CopyOnly", "Type", "CompressBackup", "Checksum", "Verify", "AzureCredential", "CreateFolder". .PARAMETER AzureCredential The name of the credential on the SQL instance that can write to the AzureBaseUrl, only needed if using Storage access keys If using SAS credentials, the command will look for a credential with a name matching the AzureBaseUrl .PARAMETER NoRecovery This is passed in to perform a tail log backup if needed .PARAMETER BuildPath By default this command will not attempt to create missing paths, this switch will change the behaviour so that it will .PARAMETER IgnoreFileChecks This switch stops the function from checking for the validity of paths. This can be useful if SQL Server only has read access to the backup area. Note, that as we cannot check the path you may well end up with errors. .PARAMETER OutputScriptOnly Switch causes only the T-SQL script for the backup to be generated. Will not create any paths if they do not exist .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .NOTES Tags: DisasterRecovery, Backup, Restore Author: Stuart Moore (@napalmgram), stuart-moore.com Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .EXAMPLE PS C:\> Backup-DbaDatabase -SqlInstance Server1 -Database HR, Finance This will perform a full database backup on the databases HR and Finance on SQL Server Instance Server1 to Server1 default backup directory. .EXAMPLE PS C:\> Backup-DbaDatabase -SqlInstance sql2016 -BackupDirectory C:\temp -Database AdventureWorks2014 -Type Full Backs up AdventureWorks2014 to sql2016 C:\temp folder. .EXAMPLE PS C:\> Backup-DbaDatabase -SqlInstance sql2016 -AzureBaseUrl https://dbatoolsaz.blob.core.windows.net/azbackups/ -AzureCredential dbatoolscred -Type Full -CreateFolder Performs a full backup of all databases on the sql2016 instance to their own containers under the https://dbatoolsaz.blob.core.windows.net/azbackups/ container on Azure blog storage using the sql credential "dbatoolscred" registered on the sql2016 instance. .EXAMPLE PS C:\> Backup-DbaDatabase -SqlInstance sql2016 -AzureBaseUrl https://dbatoolsaz.blob.core.windows.net/azbackups/ -Type Full Performs a full backup of all databases on the sql2016 instance to the https://dbatoolsaz.blob.core.windows.net/azbackups/ container on Azure blog storage using the Shared Access Signature sql credential "https://dbatoolsaz.blob.core.windows.net/azbackups" registered on the sql2016 instance. .EXAMPLE PS C:\> Backup-Dbadatabase -SqlInstance Server1\Prod -Database db1 -BackupDirectory \\filestore\backups\servername\instancename\dbname\backuptype -Type Full -ReplaceInName Performs a full backup of db1 into the folder \\filestore\backups\server1\prod\db1 .EXAMPLE PS C:\> Backup-Dbadatabase -SqlInstance Server1\Prod -BackupDirectory \\filestore\backups\servername\instancename\dbname\backuptype -BackupFileName dbname-backuptype-timestamp.trn -Type Log -ReplaceInName Performs a log backup for every database.
