Getting the "Backup ID" from the Session Details of a FS or Group Replication

Hello,

i work on a script that checks if all object are successfully replicated in a replication job.

If i check the details of a replication session via omnidb:

omnidb -session $REPSESSIONID -detail

I get a outplut like:

Object name : testserver.local:/ '/usr/share'
        Object type        : FileSystem
        Object status      : Completed
        Started            : Mon 27 Mar 2017 11:00:05 PM CEST
        Finished           : Mon 27 Mar 2017 11:01:05 PM CEST
        Object size        : 30040 KB
        Backup type        : Incremental1
        Protection         : Protected for 13 days
        Catalog retention  : Same as data protection.
        Version type       : Normal
        Access             : Private
        Number of warnings : 0
        Number of errors   : 0
        Device name        : DC1_CAT20_REP_dptest
        Backup ID          : n/a
        Copy ID            : 5F2B0121-4F2B-481D-B79F-2DC827B85093/12326773 (Copy)
        Encrypted          : No
        DiskAgent ID       : 1490648403

For oracle Backups, the "Backup ID" is given, but for FS or Group-Backups, the "Backup ID" is "n/a".

How can i get a list of Backup-IDs used in the Replication or can i lookup the Backup-ID via the "Copy ID" somehow (i would prefer this method anyway but can't find a usable command) ?

In the next step i list all Objects from the Replication and from the Backup and make a diff to check if anything is missing, this works fine for Oracle but as i said, i have no clue how the get the Backup ID for FS or Group.

Kind Regards
