Creating a one-time database backup


We're now going to show you how to make a one-off snapshot of your database. You might opt to do this if you have a specific requirement around keeping a point in time backup of your DB. You might also want to take a snapshot for the purpose of creating a new working copy of your dataset.

Getting ready

In order to proceed you're going to need the following:

  • A unique identifier that you'd like to assign to this snapshot

The snapshot identifier has some constraints:

  • It needs to start with a letter
  • It must not be longer than 255 characters

How to do it...

Type the following AWS CLI command to initiate the creation of a snapshot. You'll need to wait for a few minutes for the snapshot to complete...
