Returns backup history details for databases on a SQL Server Availability Group.
Returns backup history details for some or all databases on a SQL Server Availability Group.
You can even get detailed information (including file path) for latest full, differential and log files.
For detailed examples of the various parameters see the documentation of Get-DbaDbBackupHistory.

PS C:\> Get-DbaAgBackupHistory -SqlInstance AgListener -AvailabilityGroup AgTest1
Returns information for all database backups still in msdb history on all replicas of availability group AgTest1 using the listener AgListener to determine all replicas.
PS C:\> Get-DbaAgBackupHistory -SqlInstance Replica1, Replica2, Replica3 -AvailabilityGroup AgTest1
Returns information for all database backups still in msdb history on the given replicas of availability group AgTest1.
PS C:\> Get-DbaAgBackupHistory -SqlInstance 'Replica1:14331', 'Replica2:14332', 'Replica3:14333' -AvailabilityGroup AgTest1
Returns information for all database backups still in msdb history on the given replicas of availability group AgTest1 using custom ports.
PS C:\> $ListOfReplicas | Get-DbaAgBackupHistory -AvailabilityGroup AgTest1
Returns information for all database backups still in msdb history on the replicas in $ListOfReplicas of availability group AgTest1.

PS C:\> $allAgResults | Format-Table
Returns information for all database backups on all replicas for all availability groups on SQL instance MyServer.
The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.
If you pass in one availability group listener, all replicas are automatically determined and queried.
If you pass in a list of individual replicas, they will be queried. This enables you to use custom ports for the replicas.
| Alias | |
| Required | True |
| Pipeline | true (ByValue) |
| Default Value |
Specify the availability group to process.
| Alias | |
| Required | True |
| Pipeline | false |
| Default Value |
Credential object used to connect to the SQL Server instance as a different user. This can be a Windows or SQL Server account. Windows users are determined by the existence of a backslash, so if you
are intending to use an alternative Windows connection instead of a SQL login, ensure it contains a backslash.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Specifies one or more database(s) to process. If unspecified, all databases of the availability group will be processed.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Specifies one or more database(s) to exclude from processing.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
By default Get-DbaAgBackupHistory will ignore backups taken with the CopyOnly option. This switch will include them.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
If this switch is enabled, a large amount of information is returned, similar to what SQL Server itself returns.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
Specifies a DateTime object to use as the starting point for the search for backups.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | (Get-Date '01/01/1970') |
Specifies the Recovery Fork you want backup history for
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
If this switch is enabled, the most recent full chain of full, diff and log backup sets is returned.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
If this switch is enabled, the most recent full backup set is returned.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
If this switch is enabled, the most recent differential backup set is returned.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
If this switch is enabled, the most recent log backup is returned.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
Specifies a filter for backup sets based on DeviceType. Valid options are 'Disk','Permanent Disk Device', 'Tape', 'Permanent Tape Device','Pipe','Permanent Pipe Device','Virtual Device','URL', in
addition to custom integers for your own DeviceType.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
If this switch is enabled, one object per backup file is returned. Otherwise, media sets (striped backups across multiple files) will be grouped into a single return object.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
Specifies a minimum LSN to use in filtering backup history. Only backups with an LSN greater than this value will be returned, which helps speed the retrieval process.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
By default mirrors of backups are not returned, this switch will cause them to be returned
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
Specifies one or more types of backups to return. Valid options are 'Full', 'Log', 'Differential', 'File', 'Differential File', 'Partial Full', and 'Partial Differential'. Otherwise, all types of
backups will be returned unless one of the -Last* switches is enabled.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | |
| Accepted Values | Full,Log,Differential,File,Differential File,Partial Full,Partial Differential |
Specifies which of the returned LSN values you would like to use for sorting when using the LastFull, LastDiff and LastLog parameters.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | FirstLsn |
| Accepted Values | FirstLsn,DatabaseBackupLsn,LastLsn |
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.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
