Hi all.

I warn you: This is a rather philosophical question. Some might think this 
is a dummy question. If your one of those, perhaps you have something to 
share. I wish there was some standard to follow in these things. I have the 
feeling I'm not alone wandering about this.

I would like to have your opinioun about data management on an EDL in 
conjunction with Networker.

In our case we're using the EDL to backup data with 4-8 weeks retention. 
Complete size of the whole mess is about 40TB. Thats the one-time-Full-
Backup-of-Everything data size. Then we need to keep all the data for the 
duration of the retention time plus the incrementals. But we only have 
100TB of EDL storage which can store about 200TB of data (with 
compression). 

Now what I'm thinking about is wheter or not we're going to load everything 
on the EDL and keep the retention periods very short, or if we should do 
some cloning to an external medium such as a phisical library. 

It probably depends on the kind of data.
-email
-financial databases
-other databases
-fileserver data

Is it necessary to store this kind of data longer than 4 - 12 weeks? 

It would be intriguing to know about how others are solving this.
