Hallo, turn for a while TSM compression on (in contrast to HW-tape compression you are probably using now). This will not change things, but it gives you statistics how your data are beeing compressed during backup. Your HW compression does simillar thing with simillar results.
Probably you have files on netware which can be compressed very well, maybe modestly used database files. If your boss does not believe TSM´s statistics take WinZip or something like that and compress 1 GB of typicall data both on Netware and on Windows and compare the resulting file size. Turn the argumentation to the fact your users on Netware server use tons of redundant data, most likely consisting to two thirds of spaces only :-) :-)) juraj -----Ursprüngliche Nachricht----- Von: anton walde [mailto:[EMAIL PROTECTED] Gesendet: Mittwoch, 03.

I have a question concerning tape usage: we have two sites, one using Windows and one using Netware. we make the same at both sites, incremental forever, no special taks like archive or aomething like that. Now we see the following: while the Netware-site is using the LTO1-Tapes with 180-300 GB per tape, the windows-site is using the same tapes with 120-140 GB par tape. >From where does this great difference come from? Is compression a part of the problem? or is it a problem of what tsm tells and what really is? Please help me, my bos is going to kill me, because we need tapes and tapes for 'no data' while for the big amounts we need none!!! -- +++ NEU bei GMX und erstmalig in Deutschland: T\V-gepr|fter Virenschutz +++ 100% Virenerkennung nach Wildlist.
