Description

Describes one or more of the EBS snapshots available to you. Available snapshots include public snapshots available for any AWS account to launch, private snapshots that you own, and private snapshots owned by another AWS account but for which you've been given explicit create volume permissions. The create volume permissions fall into the following categories:

public: The owner of the snapshot granted create volume permissions for the snapshot to the all group. All AWS accounts have create volume permissions for these snapshots.
explicit: The owner of the snapshot granted create volume permissions to a specific AWS account.
implicit: An AWS account has implicit create volume permissions for all snapshots it owns.

The list of snapshots returned can be modified by specifying snapshot IDs, snapshot owners, or AWS accounts with create volume permissions. If no options are specified, Amazon EC2 returns all snapshots for which you have create volume permissions. If you specify one or more snapshot IDs, only snapshots that have the specified IDs are returned. If you specify an invalid snapshot ID, an error is returned. If you specify a snapshot ID for which you do not have access, it is not included in the returned results. If you specify one or more snapshot owners using the OwnerIds option, only snapshots from the specified owners and for which you have access are returned. The results can include the AWS account IDs of the specified owners, amazon for snapshots owned by Amazon, or self for snapshots that you own. If you specify a list of restorable users, only snapshots with create snapshot permissions for those users are returned. You can specify AWS account IDs (if you own the snapshots), self for snapshots for which you own or have explicit permissions, or all for public snapshots. If you are describing a long list of snapshots, you can paginate the output to make the list more manageable. The MaxResults parameter sets the maximum number of results returned in a single page. If the list of results exceeds your MaxResults value, then that number of results is returned along with a NextToken value that can be passed to a subsequent DescribeSnapshots request to retrieve the remaining results. For more information about EBS snapshots, see Amazon EBS Snapshots in the Amazon Elastic Compute Cloud User Guide.

This operation automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output.

Parameters

-Filter <Filter[]>

One or more filters.

description - A description of the snapshot.
owner-alias - Value from an Amazon-maintained list (amazon | aws-marketplace | microsoft) of snapshot owners. Not to be confused with the user-configured AWS account alias, which is set from the IAM console.
owner-id - The ID of the AWS account that owns the snapshot.
progress - The progress of the snapshot, as a percentage (for example, 80%).
snapshot-id - The snapshot ID.
start-time - The time stamp when the snapshot was initiated.
status - The status of the snapshot (pending | completed | error).
tag:key=value - The key/value combination of a tag assigned to the resource. Specify the key of the tag in the filter name and the value of the tag in the filter value. For example, for the tag Purpose=X, specify tag:Purpose for the filter name and X for the filter value.
tag-key - The key of a tag assigned to the resource. This filter is independent of the tag-value filter. For example, if you use both the filter "tag-key=Purpose" and the filter "tag-value=X", you get any resources assigned both the tag key Purpose (regardless of what the tag's value is), and the tag value X (regardless of what the tag's key is). If you want to list only resources where Purpose is X, see the tag:key=value filter.
tag-value - The value of a tag assigned to the resource. This filter is independent of the tag-key filter.
volume-id - The ID of the volume the snapshot is for.
volume-size - The size of the volume, in GiB.

-MaxResult <Int32>

The maximum number of snapshot results returned by DescribeSnapshots in paginated output. When this parameter is used, DescribeSnapshots only returns MaxResults results in a single page along with a NextToken response element. The remaining results of the initial request can be seen by sending another DescribeSnapshots request with the returned NextToken value. This value can be between 5 and 1000; if MaxResults is given a value larger than 1000, only 1000 results are returned. If this parameter is not used, then DescribeSnapshots returns all results. You cannot specify this parameter and the snapshot IDs parameter in the same request.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.

Required?	False
Position?	Named
Accept pipeline input?	False

-NextToken <String>

The NextToken value returned from a previous paginated DescribeSnapshots request where MaxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the NextToken value. This value is null when there are no more results to return.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.

Required?	False

-OwnerId <String[]>

Returns the snapshots owned by the specified owner. Multiple owners can be specified.

Required?	False
Position?	2
Accept pipeline input?	False

-RestorableByUserId <String[]>

One or more AWS accounts IDs that can create volumes from the snapshot.

Required?	False
Position?	3
Accept pipeline input?	False

-SnapshotId <String[]>

One or more snapshot IDs.Default: Describes snapshots for which you have launch permissions.

Required?	False
Position?	1
Accept pipeline input?	True (ByValue, ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>

The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.

Required?	False
Position?	Named
Accept pipeline input?	False

-Credential <AWSCredentials>

An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.

Required?	False
Position?	Named
Accept pipeline input?	False

-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required?	False
Position?	Named
Accept pipeline input?	False

-ProfileName <String>

The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.

Required?	False
Position?	Named
Accept pipeline input?	False

-NetworkCredential <PSCredential>

Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.

Required?	False
Position?	Named
Accept pipeline input?	False

-SecretKey <String>

The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.

Required?	False
Position?	Named
Accept pipeline input?	False

-SessionToken <String>

The session token if the access and secret keys are temporary session-based credentials.

Required?	False
Position?	Named
Accept pipeline input?	False

-Region <String>

The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.

Required?	False
Position?	Named
Accept pipeline input?	False

-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required?	False
Position?	Named
Accept pipeline input?	False

Inputs
