Re: Backing Up 100 Terabytes of Data

[Joel Rosenblatt <joel () COLUMBIA EDU>]

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.
