How to implement snapshots
It can take up to 12 hours or more to process a full backup job and move the entire backup volume to tape or disk. For many companies, that's just too much time. IT departments can use snapshots to capture entire storage environments, or simply track changes to the state of mission-critical systems. Snapshots can establish recovery points in just a fraction of the time... More...

FAQ's
What type of data reduction ratios should you realistically expect using deduplication?
with backup; backup appliances performing deduplication or even virtual tape libraries (VTL). So, looking at it in that context, you'll hear advertised ratios of anywhere from 10 to 500X.

But, realistically, I think it's safe to assume a ratio of anywhere between 13 to 17X. You'll probably see lower ratios on target... More...

Are there any major drawbacks to using tape encryption?
order to work. If you start encrypting your data at the source to put it on tape, that will completely destroy your ability to apply deduplication. So that is something worth considering. You can not have both.

If you are encrypting at the device level, it takes care of that problem, but then you are not... More...
