Unable to add existing backups
Been using TI2018 for quite a while, but only for backups, never had to restore. Now I need to but am unable to add existing backups. I have numerous ones, all *.tib, on different drives and am unable to add any of them, even the one I made yesterday. I don't get any error messages just nothing happens. Tried the cleanup tool and no different. Any suggestions? All are full backups.
