Simple: Say, I have 1 TB disk for vtapes. I can create 900 vtapes on this disk. But all of dumps have ~500MB, so only half of disk are used. And only 900 days are remebered. And I'm curious if I have better utilization for disk, so I can have longer period of dumps. For now, if I understand correctly, I can only do statistical estimate? Another case: I create vtapes which are +- DVD size, and it's rather important for me not to have "tapes" with only some bytes on them. In other post you said: --8<---------------cut here---------------start------------->8--- Not sure why you change the disk every days, but it's generally BAD unless you do full every night. --8<---------------cut here---------------end--------------->8--- Does this have something common with message at: http://www.mail-archive.com/[email protected]/msg46666.html ?
