I am IT everything man at a small company. I want to design a new infrastructure including a new server and a separate backup server with company wide backup policy.
The most important thing in the company is the SQL Server and its databases. There are 10 database, but only 2 of them are really important. The first one 8GB, mostly text data and numbers. The second one about 300GB with 16GB/month grow containing PDFs and GIFs.
To save the storage current backup policy consists of one full backup per week and 6 differentials. I think its about 350GB per week, 1.4TB per month.
After reading so articles about silent data corruption I decided to try ZFS with Nexenta Community edition.
My question: is ZFS with deduplication good for storing backup files in term of reliability or should i think about some tape backup or something else?
EDIT: I know that right now we cannot predict performance, deduplication ratio etc, but I want to know if it is a good idea at all.
