Then it also checks existing snapshots and deletes ones older than the retention period. This cmdlet is designed to be run as a recurring scheduled task. Only snapshots that were created through this cmdlet will be reviewed for deletion by using a tag "CreatedBy" : "17701dbb-33ff-4f31-8914-6f48856fe755", a unique Id used by this cmdlet. Snapshots can also be marked as non-deletable by specifying DoNotDelete or manually adding a tag to the snapshot "CanDelete" : "false". The cmdlet requires the EC2 instance to have an IAM Instance Profile (IAM Role) that allows it to list volumes, list snapshots, list instances, create snapshots, and delete snapshots, similar to the following example: { "Version": "2012-10-17", "Statement": [ { "Sid": "Automated EBS Snapshot Management", "Effect": "Allow", "Action": [ "ec2:CreateSnapshot", "ec2:DeleteSnapshot", "ec2:DescribeInstances", "ec2:DescribeSnapshots", "ec2:CreateTags", "ec2:DescribeTags", "ec2:DescribeVolumes" ], "Resource": [ "*" ] } ] } .PARAMETER RetentionPeriod A TimeSpan object specifying how long snapshots should be retained before being deleted. This value is used with the Snapshot's StartTime property to determine if it should be deleted. It does not record a deleted time as a tag on the Snapshot so that if the retention period is changed in the scheduled task, existing snapshots will then use that new retention period the next time the cmdlet is run. This defaults to 30 days. .PARAMETER DoNotDelete Specifies that the snapshots that are created should not be automatically deleted. If this is specified, you cannot specify a retention period. .PARAMETER EnableLogging Enables writing a log file to %SYSTEMDRIVE%\AwsLogs\EBS\Backup.log with the transcript of the backup job. The log file is automatically rolled over when it exceeds 5MB. .EXAMPLE New-AutomatedEBSSnapshot -RetentionPeriod (New-TimeSpan -Days 45) Creates a new EBS snapshot of the current EC2 instance's volumes and then deletes any snapshots of the instance's volumes that are marked as deletable and are older than 45 days. .INPUTS None .OUTPUTS None .NOTES AUTHOR: Michael Haken LAST UPDATE: 5/3/2017 #> [CmdletBinding(DefaultParameterSetName = "Retention")] Param( [Parameter(ParameterSetName = "Retention")] [System.TimeSpan]$RetentionPeriod = (New-TimeSpan -Days 30), [Parameter(ParameterSetName = "DoNotDelete")] [switch]$DoNotDelete, [Parameter()] [switch]$EnableLogging ) Begin { Function Write-EBSLog { Param( [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [System.String]$Message, [Parameter()] [ValidateSet("INFO", "WARNING", "ERROR")] [System.String]$Level = "INFO", [Parameter()] [System.String]$Path = "$env:SystemDrive\AwsLogs\EBS\Backup.log", [Parameter()] [switch]$NoTimeStamp ) Begin { } Process { [System.IO.FileInfo]$Info = New-Object -TypeName System.IO.FileInfo($Path) if (-not [System.IO.Directory]::Exists($Info.Directory.FullName)) { New-Item -ItemType Directory -Path $Info.Directory.FullName } if (Test-Path -Path $Path) { $Log = Get-Item -Path $LogFile if ($Log.Length -gt 5MB) { $LogDate = (Get-Date).ToString("dd-MMM-yyyy_HH-mm-ss") $Parts = $Log.Name.Split(".") $NewName = $Parts[0] + "_" + $LogDate + "." + $Parts[1] while ((Get-Item -Path "$($Info.Directory.FullName)\$NewName" -ErrorAction SilentlyContinue) -ne $null) { $LogDate = (Get-Date).ToString("dd-MMM-yyyy_HH-mm-ss") $NewName = $Parts[0] + "_" + $LogDate + "." + $Parts[1] } Rename-Item -Path $LogFile -NewName $NewName $Path = "$($Info.Directory.FullName)\$NewName" } } if(-not $NoTimeStamp) { $Message = "$(Get-Date) [$Level] : $Message" } Add-Content -Path $Path -Value $Message } End { } } } Process { if ($EnableLogging) { Write-EBSLog -Message "*******************************************************************************" -NoTimeStamp Write-EBSLog -Message "Beginning volume snapshot creation job." } try { [System.String]$Region = Get-EC2InstanceRegion if ($EnableLogging) { Write-EBSLog -Message "Setting default region to $Region" } Set-DefaultAWSRegion -Region $Region [System.String]$InstanceId = Get-EC2InstanceId if ($EnableLogging) { Write-EBSLog -Message "Getting instances." } #This is actually a [Amazon.EC2.Model.Reservation], but if no instance is returned, it comes back as System.Object[] #so save the error output and don't strongly type it $Instances = Get-EC2Instance -InstanceId $SourceInstanceId -ErrorAction SilentlyContinue if ($Instances -ne $null) { [Amazon.EC2.Model.Instance]$Instance = $Instances.Instances | Select-Object -First 1 if ($Instance -ne $null) { [System.String]$InstanceName = $Instance.Tags | Where-Object {$_.Key -eq "Name"} | Select-Object -ExpandProperty Value try { if ($EnableLogging) { Write-EBSLog -Message "Retrieving EBS Volumes for instance." } $Date = (Get-Date).ToString("dd-MMM-yyyy_HH-mm-ss") [Amazon.EC2.Model.Volume[]]$Volumes = Get-EC2Volume -Filter (New-Object -TypeName Amazon.EC2.Model.Filter -Property @{Name = "attachment.instance-id";

The destination instance can be provided as an EC2 object or by instance id. The mount point device can be specified directly or the next available device is used. If the device is specified directly and is in use, or if multiple volumes are specified, the provided device is used as a starting point to find the next available device. .PARAMETER VolumeIds The Ids of the volumes to attach. The must be in an available status. .PARAMETER NextAvailableDevice Specifies that the cmdlet will find the next available device between xvdb and xvdp. .PARAMETER Device Specify the device that the volume will be attached at. If multiple volumes are specified, this is the starting point to find the next available device for each. .PARAMETER InstanceId The id of the instance to attach the volumes to. .PARAMETER Instance The Amazon.EC2.Model.Instance object to attach the volumes to. .PARAMETER Region The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc. This defaults to the default regions set in PowerShell, or us-east-1 if not default has been set. .PARAMETER AccessKey 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. .PARAMETER SecretKey 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. .PARAMETER SessionToken The session token if the access and secret keys are temporary session-based credentials. .PARAMETER Credential An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials. .PARAMETER ProfileLocation 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. .PARAMETER ProfileName 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. .EXAMPLE Mount-EBSVolumes -VolumeIds vol-04d16ab9a1b07449g -InstanceId i-057bd4fe22eced7bb -Region ([Amazon.RegionEndpoint]::USWest1) .INPUTS None .OUTPUTS None .NOTES AUTHOR: Michael Haken LAST UPDATE: 6/5/2017 #> [CmdletBinding()] Param( [Parameter(Mandatory = $true, ParameterSetName = "IdAndNextAvailable")] [Parameter(Mandatory = $true, ParameterSetName = "InputObjectAndNextAvailable")] [ValidateNotNull()] [System.String[]]$VolumeIds, [Parameter(ParameterSetName = "InputObjectAndNextAvailable", Mandatory = $true)] [Parameter(ParameterSetName = "IdAndNextAvailable", Mandatory = $true)] [switch]$NextAvailableDevice, [Parameter(ParameterSetName = "InputObjectAndDevice", Mandatory = $true)] [Parameter(ParameterSetName = "IdAndDevice", Mandatory = $true)] [ValidateSet("xvdb", "xvdc", "xvdd", "xvde", "xvdf", "xvdg", "xvdh", "xvdi", "xvdj", "xvdk", "xvdl", "xvdm", "xvdn", "xvdo", "xvdp", "xvdq")] [System.String]$Device, [Parameter(Mandatory = $true, ParameterSetName = "IdAndDevice")] [Parameter(Mandatory = $true, ParameterSetName = "IdAndNextAvailable")] [ValidateNotNullOrEmpty()] [System.String]$InstanceId, [Parameter(Mandatory = $true, ParameterSetName = "InputObjectAndDevice")] [Parameter(Mandatory = $true, ParameterSetName = "InputObjectAndNextAvailable")] [Amazon.EC2.Model.Instance]$Instance, [Parameter()] [ValidateNotNull()] [Amazon.RegionEndpoint]$Region, [Parameter()] [ValidateNotNull()] [System.String]$ProfileName = [System.String]::Empty, [Parameter()] [ValidateNotNull()] [System.String]$AccessKey = [System.String]::Empty, [Parameter()] [ValidateNotNull()] [System.String]$SecretKey = [System.String]::Empty, [Parameter()] [ValidateNotNull()] [System.String]$SessionToken = [System.String]::Empty, [Parameter()] [ValidateNotNull()] [Amazon.Runtime.AWSCredentials]$Credential, [Parameter()] [ValidateNotNull()] [System.String]$ProfileLocation = [System.String]::Empty ) Begin { } Process { [System.Collections.Hashtable]$Splat = New-AWSSplat -Region $Region -ProfileName $ProfileName -AccessKey $AccessKey -SecretKey $SecretKey -SessionToken $SessionToken -Credential $Credential -ProfileLocation $ProfileLocation if ($PSCmdlet.ParameterSetName.StartsWith("Id")) { $Destination = Get-EC2Instance -InstanceId $InstanceId @Splat | Select-Object -ExpandProperty Instances | Select-Object -First 1 } [System.String]$DeviceBase = "xvd" [System.Int32]$CurrentLetter = 0 if ($NextAvailableDevice) { #If you map an EBS volume with the name xvda, Windows does not recognize the volume. $CurrentLetter = [System.Int32][System.Char]'b' } else { $CurrentLetter = [System.Int32][System.Char]$Device.Substring($Device.Length -
