Re: Backing Up 100 Terabytes of Data

["Sarazen, Daniel" <dsarazen () UMASSP EDU>]

Thanks Joel,

This is the exact scenario. 30 Years of research, stored on multiple
servers/desktops. 

Most of the data can be backed up once and stored (not including
updating the storage media as technology evolves), with more frequent
back-ups for the new, accumulating data.   

My REAL problem? The researchers don't want to pay a lot for back-up
systems and storing. They want every dollar possible devoted to
developing new data, so I'm trying to find the most cost effective
solution. 

And yes, the backups would be solely for DR purposes. 

Thanks,

Hi,

You did not say anything about the nature of the data.  Many researchers
have large amounts of data that is relatively static - they collect it
over time and 
the older data never changes - they just keep on adding data to the end
of the collection.

If that is the case, then backup speed is not all that important - you
will need to do one massive backup at first, and then small incremental
backups of the 
additional or changing data from then on.

The assumption in this case is that the backup is purely for DR and not
for online access.

Another thing to look at is the type of data - many times, the data is
sparse and can be highly compressed.

My 2 cents.
