Parameters
-AccessToken
The access token used to authenticate to SQL Server, as an alternative to user/password or Windows Authentication.
This can be used, for example, to connect to SQL Azure DB and SQL Azure Managed Instance
using a Service Principal or a Managed Identity.
The parameter to use can be either a string representing the token or a PSAccessToken object as returned by running Get-AzAccessToken -ResourceUrl https://database.windows.net.
This parameter is new in v22 of the module.
| Type: | PSObject |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-BackupType
The type of backup to filter on. If not specified then gets all backup types. Accepted values are defined below.
| Type: | BackupSetType |
| Accepted values: | Database, Differential, Incremental, Log, FileOrFileGroup, FileOrFileGroupDifferential |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ConnectionTimeout
The time to wait in seconds for a connection to be established and the dynamically generated -DatabaseName parameter to be populated.
| Type: | Int32 |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Credential
The PSCredential object whose username and password fields are used to connect to the SQL instance.
| Type: | PSCredential |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-DatabaseName
The names of the databases whose backup records are to be retrieved. This is a dynamically populated field and so provides auto-complete suggestions on database names.
| Type: | System.Collections.Generic.List`1[System.String] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Encrypt
The encryption type to use when connecting to SQL Server.
This value maps to the Encrypt property SqlConnectionEncryptOption on the SqlConnection object of the Microsoft.Data.SqlClient driver.
In v22 of the module, the default is Optional (for compatibility with v21). In v23+ of the module, the default value will be 'Mandatory', which may create a breaking change for existing scripts.
This parameter is new in v22 of the module.
| Type: | String |
| Accepted values: | Mandatory, Optional, Strict |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-EndTime
The time before which all backup records to be retrieved should have completed.
| Type: | DateTime |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-HostNameInCertificate
The host name to be used in validating the SQL Server TLS/SSL certificate. You must pass this parameter if your SQL Server instance is enabled for Force Encryption and you want to connect to an instance using hostname/shortname. If this parameter is omitted then passing the Fully Qualified Domain Name (FQDN) to -ServerInstance is necessary to connect to a SQL Server instance enabled for Force Encryption.
This parameter is new in v22 of the module.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-IgnoreProviderContext
Indicates that this cmdlet does not use the current context to override the values of the ServerInstance, DatabaseName parameters. If you do not specify this parameter, the cmdlet ignores the values of these parameters, if possible, in favor of the context in which you run the cmdlet.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |

This switch will make the cmdlet obtain records for snapshot backups as well. By default such backups are not retrieved.
| Type: | SwitchParameter |
| Position: | Named |

-Since
Specifies an abbreviation that you can instead of the StartTime parameter.
It can be specified with the EndTime parameter.
You cannot use the StartTime parameter, if you use this parameter.
The acceptable values for this parameter are:
- Midnight (gets all the job history information generated after midnight)
- Yesterday (gets all the job history information generated in the last 24 hours)
- LastWeek (gets all the job history information generated in the last week)
- LastMonth (gets all the job history information generated in the last month)
