Hi @mh158 ,
Please check below command
curl -s -u "admin:admin" http://localhost:4502/system/console/jmx/com.adobe.granite:type=Repository | grep -ie 'BackupInProgress\|BackupProgress\|BackupWasSuccessful' | sed -e "s/<[-a-zA-Z=\'?.\{\}&;:\/, ]*>/ /g" | sed -e 's/^ *//g' | sed 's/ */ /g'
Additionally, you may track it through backup console here:
https://<*hostname*>:<*port-number*>/libs/granite/backup/content/admin.html
where a progress bar will indicate the progress of the backup.
For more details please refer [0].
