Hello.

As I understand it the dedup in Avamar is based on your entire backup pool.

So it will use deduplication not only based on the database being backed up but also it can use data from another database not even on that server or platform. This makes it more powerful. So if you have 5 Full backups in Avamar, you really only need to know that you have 5 full backups. In the Avamar Admin Console it will show 5 different full backups while on disk or storage it does not store 5 times the database size. Avamar uses some complex algorithms and processes to store the data in a deduped and compressed fashion leverage data that it already has matching data you are backing up. I hope this helps. Please let me know if you have other questions.

Thanks

Mark
