tape are DDS2 ones and tape drive is cleaned once a week while I backup 5 times
a week.
Tapes are one year/ six months old. I'm already looking for informations about
HP C5707A DDS2 or SONY DGD120P DDS tapes so that I can systematically replace
them but all I can find is that these are tapes with warranty lifetime (BTW,
does anyone know how many times these DDS2 tapes can be used and should be
replaced?)
Tape drive (HP SureStore DAT 8) is two years old.

Regards.
