Create an EBS Snapshot
Table of contents
An EBS Snapshot represents a volume at a particular point in time. Although you can take an EBS Snapshot of an EBS Volume regardless of whether or not the volume is attached to a running instance, it is strongly recommeded that you either detach or freeze all writes to a volume before taking a snapshot in order to prevent any data loss or corruption. If you do not take these necessary precautions, your data will not be in synch and you could possibly lose or corrupt data on the disk.
WARNING!
The data on your volume can be corrupted if you do not properly detach/freeze a volume before taking a snapshot. As a best practice, you should always make sure that no writes are being made to a volume before taking a snapshot.
Before you Create a Snapshot of an EBS Volume
- Freeze the volume (if supported by the file system)
- Make sure that all files are closed and that there are no pending writes to the disk.
To create an EBS Snapshot, go to Manage -> Storage -> EBS Volumes, and click a volume's Run button.
You can also click the Snapshot button from an EBS Volume's homepage.
Provide a short description of the volume. By default, the Nickname will include a timestamp of the snapshot (yymmdd - hhmm). Click Create.
A confirmation window will track the progress of your snapshot.
