I hit this error when I’m trying to restore a couchbase backup

/opt/couchbase/bin/cbbackupmgr restore --archive backup_13082019 --repo backup --cluster couchbase:// --disable-eventing -u -p -t 4

Is there a way to say to the restore mechanism to retry sending a record if it failed ?
I have around 490000 records to restore but when done I only see 430000
