Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Viewing the common snapshot

The common snapshot is used to maintain incrementality between your backups. This procedure explains how to identity the common snapshot on your volume.

To view a volume's common snapshot

  • To determine which snapshot is a volume's common snapshot, use the volume snapshot show ONTAP CLI command. 

    volume snapshot show -volume volume-name

    In the output, the name of the common snapshot has the format of backup-id, where id is a 17 digit alphanumeric string, as shown in the following example:

    FsxIdabc12345::> volume snapshot show -volume test_vol
                                 ---Blocks---

Important

Do not delete the common snapshot on the volume because it is used to maintain incrementality between your backups. Deleting a volume's common snapshot will cause the next backup to be a full backup of the volume instead of an incremental backup.
