Does JetBackup 5 have similar API calls as JetBackup 4 did for the UAPI, such as listing a backup for a user?
jetbackup5api now handles JetBackup api calls on both the admin and user side with the proper privilege handling.
uapi --user=acct01 JetBackup listBackups type=127 for example, the equivalent api call for a cPanel user level would be :
jetbackup5api -F listBackups -D "type=1&contains=511"
This would list the Full Backups that it owns. For further information on the JetBackup 5 API, please review the offifical documentation at JetBackup v5.1 API.
