Hi All,

In our environment , we have noticed that the data content/Size written on the tapes are not up-to the actual capable size. when i check images available in a tape, i do see that there are Fragmented images(i.e. Expired images).

Need to know, is there a way, i can delete them automatically(Like a schedule). we have the expire image deletion on disk. I would like to know if i can do it in Tape.

Apologies if the query sounds silly, Just looking for some clarity.

Thanks.

Not possible due to the sequential way that tapes are written.

Only when all images on tape have expired can the tape be overwritten from the start.
