Description

Describes the specified EBS snapshots available to you or all of the EBS snapshots available to you. The snapshots available to you include public snapshots, private snapshots that you own, and private snapshots owned by other AWS accounts for which you have 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 cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Note: For scripts written against earlier versions of this module this cmdlet can also be invoked with the alias, Get-EC2Snapshots.

Parameters

-Filter <Filter[]>
The filters.
  • description - A description of the snapshot.
  • encrypted - Indicates whether the snapshot is encrypted (true | false)
  • owner-alias - Value from an Amazon-maintained list (amazon | self | all | 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> - The key/value combination of a tag assigned to the resource. Use the tag key in the filter name and the tag value as the filter value. For example, to find all resources that have a tag with the key Owner and the value TeamA, specify tag:Owner for the filter name and TeamA for the filter value.
  • tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.
  • 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: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems, MaxResults
-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.
In order to manually control output pagination, use '-NextToken $null' for the first call and '-NextToken $AWSHistory.LastServiceResponse.NextToken' for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of NextToken as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-OwnerId <String[]>
Describes the snapshots owned by these owners.
Required?False
Position?2
Accept pipeline input?True (ByPropertyName)
AliasesOwnerIds
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the SnapshotId parameter. The -PassThru parameter is deprecated, use -Select '^SnapshotId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-RestorableByUserId <String[]>
The IDs of the AWS accounts that can create volumes from the snapshot.
Required?False
Position?3
Accept pipeline input?True (ByPropertyName)
AliasesRestorableByUserIds
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'Snapshots'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EC2.Model.DescribeSnapshotsResponse). Specifying the name of a property of type Amazon.EC2.Model.DescribeSnapshotsResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-SnapshotId <String[]>
The snapshot IDs.Default: Describes the snapshots for which you have create volume permissions.
Required?False
