You have to state what drive techology you want to use. As an example if you
choose fromt Technologies you might have a matrix as such.

DLT  ADIC,ATL,STK
AIT2  ADIC,Spectra Logic,Qualstar
DTF    ADIC,SONY
9840    STK
3590   ADIC,IBM,STK

You also should look at what type of capicty you will need.

we using the following formula


Total Capacity = (((V + ((0.25 * V) * 5)) * R) - ((R / 4) * V)) + (V * M)

Where:

V = the total amount of data to be backed up.
        
R = Number of weeks that non-monthend data should be kept for before being
recycled.

M = Number of months that monthend data should be kept on-line in the silo.
 


All disk drives are rated in MTBF
That's mean time between failures.
The question is not if your disk will crash but when.
Got BACKUP?

Subject: [Veritas-bu] Buying a new Robot


I have finally been given a budget to purchase our first real robot tape
drive library.  
I know there are probably horror stories for every piece of hardware ever
built, but 

If you have strong feelings either for or against a particular tape library
and care to share them, I would appreciate any insights.  Please be specific
in the reasons
thanks very much
anthony kratunis
