This article gives you an easy-to-understand LifeCycle for your LEVIIA Storag3 buckets, with 3 of the most frequently used examples:

• Automatically deleting expired delete markers
• Managing obsolete versions of versioned objects
• Cleaning up incomplete multipart uploads

1. Expired delete markers:

This rule automatically cleans up expired delete markers.

A delete marker is considered expired when it is the only remaining version of an object (all other versions having been deleted).

{
  "Rules": [
    {
      "ID": "LEVIIA-Supprimer-Marqueurs-Expirés",
      "Status": "Enabled",
      "Filter": {},
      "Expiration": {
        "ExpiredObjectDeleteMarker": true
      }
    }
  ]
}

2. Non-current versions (obsolete versions)

Out-of-date versions will be deleted 365 days after becoming out-of-date. In addition to the current version, the 5 most recent non-current versions will be retained, even if they exceed the 365-day period.

The values for 365 days and 5 versions can be adjusted in your JSON file to suit your needs.

{
  "Rules": [
    {
      "ID": "LEVIIA-G\u00e9rer-Versions-Non-Courantes",
      "Status": "Enabled",
      "Filter": {},
      "NoncurrentVersionExpiration": {
        "NoncurrentDays": 365,
        "NewerNoncurrentVersions": 5
      }
    }
  ]
}

3. Incomplete multipart uploads

Incomplete multipart uploads will be deleted 7 days after initiation. This 7-day value can be adjusted in your JSON file to suit your needs.

{
  "Rules": [
    {
      "ID": "LEVIIA-Nettoyer-Uploads-Multipart",
      "Status": "Enabled",
      "Filter": {},
      "AbortIncompleteMultipartUpload": {
        "DaysAfterInitiation": 7
      }
    }
  ]
}

It's also possible to combine all these rules into a single one:

JSON example combining the 3 rules above:

{
  "Rules": [
    {
      "ID": "LEVIIA-Configuration-Combinée",
      "Status": "Enabled",
      "Filter": {},
      "Expiration": {
        "ExpiredObjectDeleteMarker": true
      },
      "NoncurrentVersionExpiration": {
        "NoncurrentDays": 365,
        "NewerNoncurrentVersions": 5
      },
      "AbortIncompleteMultipartUpload": {
        "DaysAfterInitiation": 7
      }
    }
  ]
}

In this combined example, the lifecycle:

• Deletes expired Delete Markers

• Deletes out-of-date versions after 365 days, while always retaining the 5 latest versions, even if these are more than 365 days old.

• Delete failed MultiParts Uploads after 7 days

Configuration anatomy for LEVIIA Storag3:

• Rules: List of lifecycle rules
  
• ID: Unique rule identifier
  
• Status: Rule status (Enabled/Disabled)
  
• Filter: Filters to target specific objects
  
• Expiration: Configuration for deletion of current objects
  
• ExpiredObjectDeleteMarker: Deletes expired deletion markers
  
• NoncurrentVersionExpiration: Configuration for older versions
  
• NoncurrentDays: Number of days before deletion
  
• NewNoncurrentVersions: (optional) Minimum number of versions to keep
  
• AbortIncompleteMultipartUpload: Configuration for incomplete uploads
  
• DaysAfterInitiation: Number of days before cleanup

Important notes:

1. Lifecycle rules are executed asynchronously, so there may be a delay between configuration and actual application.
   
2. To test your rules, we recommend that you first apply the configuration to a test bucket before using it in production.
   
3. Objects protected by S3 Object Lock (immutability) will not be deleted by lifecycle rules before the end of their retention period.
