Configuring automatic object deletion

Introduction

To help manage your Object Storage, you can specify the TTL (Time to Live) for some files. For example, by doing this you can define a time period for keeping backups. This guide explains how to delete files automatically after a set time, or on a particular date.

Requirements

  • an environment that is ready to use the OpenStack API
  • OpenStack environment variables set

Configure object deletion.

There are two ways you can delete your files:

  • after a certain number of seconds
  • on a given date

After a certain number of seconds

To do this, you will need to configure the X-Delete-After header on your objects:

root@server:~$ swift post --header "X-Delete-After: 3600" container test.txt

The test.txt file will be deleted after 1 hour.

On a given date

First of all, you need to know the deletion date in Epoch format. You can use this timestamp converter to find the value you need to enter.

Then you can enter this date in the X-Delete-Atheader:

root@server:~$ swift post --header "X-Delete-At: 1448928000" container test.txt

The test.txt file will be deleted on 01 December, 2015.
