Thanks for your reply,
That's where I am looking, in the IDB context, but the option is greyed.
One thing I just noticed: when i check the General tab for the backup, the status is still "In progress/Failures".
For context: one of the VM host had a problem during the backup and 2 objects failed (the ones I want to restart). So I guess the backup not ending properly has something to do with the situation.
I restarted the server to try and clear the ïn progress flag", but it didn't change.
I think this is what's preventing me from restarting those failed objects.
Any clue on how to clear the flag ?
Thanks
