Hi all Just a quick query to round out the year... Lets say I have two media pools, a on-site tape pool called LTO, and the offsite copy of this LTO pool called COPYPOOL. If I have generated a backup set into my standard LTO media pool, will these tapes which are holding the backup set then automatically also be copied into the COPYPOOL ? If that is the case, are there really any need to me to explicitly check out these 'backup set' tapes out of my LTO media pool / library - when there may be already an offsite copy automatically generated into the COPYPOOL ? Please advise. Happy Christmas and a safe and joyous New Year to everyone
