Required Parameters

-BackupHistory

A dbatools.BackupHistory object containing backup history records

Optional Parameters

-RestoreTime

The point in time you want to restore to

-IgnoreLogs

This switch will cause Log Backups to be ignored. So will restore to the last Full or Diff backup only

-IgnoreDiffs

This switch will cause Differential backups to be ignored. Unless IgnoreLogs is specified, restore to point in time will still occur, just using all available log backups

-DatabaseName

A string array of Database Names that you want to filter to

-ServerName

A string array of Server Names that you want to filter

-ContinuePoints

The Output of Get-RestoreContinuableDatabase while provides 'Database',redo_start_lsn,'FirstRecoveryForkID' values. Used to filter backups to continue a restore on a database Sets IgnoreDiffs, and also filters databases to only those within the ContinuePoints object, or the ContinuePoints object AND DatabaseName if both specified

-LastRestoreType

The Output of Get-DbaDbRestoreHistory -last This is used to check the last type of backup to a database to see if a differential backup can be restored

-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.
