How to delete or purge old files on S3?

Question

Are there existing solutions to delete any files older than x days?

Answer 1

You can use the following Powershell script to delete object expired after x days.

[CmdletBinding()]
Param(  
  [Parameter(Mandatory=$True)]
  [string]$BUCKET_NAME,             #Name of the Bucket

  [Parameter(Mandatory=$True)]
  [string]$OBJ_PATH,                #Key prefix of s3 object (directory path)

  [Parameter(Mandatory=$True)]
  [string]$EXPIRY_DAYS             #Number of days to expire
)

$CURRENT_DATE = Get-Date
$OBJECTS = Get-S3Object $BUCKET_NAME -KeyPrefix $OBJ_PATH
Foreach($OBJ in $OBJECTS){
    IF($OBJ.key -ne $OBJ_PATH){
        IF(($CURRENT_DATE - $OBJ.LastModified).Days -le $EXPIRY_DAYS){
            Write-Host "Deleting Object= " $OBJ.key
            Remove-S3Object -BucketName $BUCKET_NAME -Key $OBJ.Key -Force
        }
    }
}
