Examples

Example: 1

PS C:\> $History | Format-DbaBackupInformation -ReplaceDatabaseName NewDb -ReplaceDbNameInFile

Changes as database name references to NewDb, both in the database name and any restore paths. Note, this will fail if the BackupHistory object contains backups for more than 1 database

Example: 2

PS C:\> $History | Format-DbaBackupInformation -ReplaceDatabaseName @{'OldB'='NewDb';'ProdHr'='DevHr'}

Will change all occurrences of original database name in the backup history (names and restore paths) using the mapping in the hashtable.
In this example any occurrence of OldDb will be replaced with NewDb and ProdHr with DevPR

Example: 3

PS C:\> $History | Format-DbaBackupInformation -DataFileDirectory 'D:\DataFiles\' -LogFileDirectory 'E:\LogFiles\

This example with change the restore path for all data files (everything that is not a log file) to d:\datafiles
And all Transaction Log files will be restored to E:\Logfiles

Example: 4

PS C:\> $History | Format-DbaBackupInformation -RebaseBackupFolder f:\backups

This example changes the location that SQL Server will look for the backups. This is useful if you've moved the backups to a different location

Required Parameters

-BackupHistory

A dbatools backupHistory object, normally this will have been created using Select-DbaBackupInformation

Optional Parameters

-ReplaceDatabaseName

If a single value is provided, this will be replaced do all occurrences a database name
If a Hashtable is passed in, each database name mention will be replaced as specified. If a database's name does not appear it will not be replace
DatabaseName will also be replaced where it occurs in the file paths of data and log files.
Please note, that this won't change the Logical Names of data files, that has to be done with a separate Alter DB call

-ReplaceDbNameInFile

If set, will replace the old database name with the new name if it occurs in the file name

-DataFileDirectory

This will move ALL restored files to this location during the restore

-LogFileDirectory

This will move all log files to this location, overriding DataFileDirectory

-DestinationFileStreamDirectory

This move the FileStream folder and contents to the new location, overriding DataFileDirectory

-DatabaseNamePrefix

This string will be prefixed to all restored database's name

-DatabaseFilePrefix

A string that will be prefixed to every file restored

-DatabaseFileSuffix

A string that will be suffixed to every file restored

-RebaseBackupFolder

Use this to rebase where your backups are stored.

-Continue

Indicates that this is a continuing restore

-FileMapping

A hashtable that can be used to move specific files to a location.
$FileMapping = @{'DataFile1'='c:\restoredfiles\Datafile1.mdf';'DataFile3'='d:\DataFile3.mdf'}
And files not specified in the mapping will be restored to their original location
This Parameter is exclusive with DestinationDataDirectory
If specified, this will override any other file renaming/relocation options.

-PathSep

By default is Windows's style (\) but you can pass also, e.g., / for Unix's style paths

-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.
