Synopsis

Allows the restore of modified BackupHistory Objects For 90% of users Restore-DbaDatabase should be your point of access to this function. The other 10% use it at their own risk

Description

This is the final piece in the Restore-DbaDatabase Stack. Usually a BackupHistory object will arrive here from Restore-DbaDatabase via the following pipeline: Get-DbaBackupInformation | Select-DbaBackupInformation | Format-DbaBackupInformation | Test-DbaBackupInformation | Invoke-DbaAdvancedRestore

We have exposed these functions publicly to allow advanced users to perform operations that we don't support, or won't add as they would make things too complex for the majority of our users

For example if you wanted to do some very complex redirection during a migration, then doing the rewrite of destinations may be better done with your own custom scripts rather than via Format-DbaBackupInformation

We would recommend ALWAYS pushing your input through Test-DbaBackupInformation just to make sure that it makes sense to us.

Examples

 

Example: 1
PS C:\> $BackupHistory | Invoke-DbaAdvancedRestore -SqlInstance MyInstance

Will restore all the backups in the BackupHistory object according to the transformations it contains

Example: 2
PS C:\> $BackupHistory | Invoke-DbaAdvancedRestore -SqlInstance MyInstance -OutputScriptOnly
PS C:\> $BackupHistory | Invoke-DbaAdvancedRestore -SqlInstance MyInstance

First generates just the T-SQL restore scripts so they can be sanity checked, and then if they are good perform the full restore.
By reusing the BackupHistory object there is no need to rescan all the backup files again
