Re: Strange results with onbar

Hi, I have recently starting testing onbar and I did notice that a full backup (non-whole system) backs up root_dbs, log_dbs and then the non-critical dbs in alphabetical order. I do not know why, but it will not necessarily promote the best performance. I guess you could backup specific dbspaces. Just make sure you get them all.
