I changed tape catalog retention to 1 month after all tape catalog removed from dpm database . Whereas long term backup recovery point retention time is more than 1 year. Therefore I tried and produced tape catalogs and was success. But after day I saw all tape catalog deleted from dpm database. ( Tape Catalog Retension value : Prune catalog when protection group retension range expires.)
How can I do my tape catalogs persistent as long as protection group retention range?
