Backup fails with error: Snapshot '_antsle_backup' exists, probably from a backup in progress.

Backup fails with error: Snapshot '_antsle_backup' exists, probably from a backup in progress.

If a backup fails with the following error:
Snapshot '_antsle_backup' exists, probably from a backup in progress. If this is not the case, please delete it and try again.
From the antsle's command line: https://docs.antsle.com/get-started/log-in-to-the-edgelinux-os-and-antlets
You can remove the snapshot with the following command
zfs destroy ZPOOL/ANTLET_NAME@_antsle_backup
For an antlet named 'apache01' on the 'antlets' zpool, use:
zfs destroy antlets/apache01@_antsle_backup
Then you should be able to try the backup again
