Hi,

It is a standard bacula configuration, data will also not change much.  So from your estimate with compression a 3TB drive would seem the minimum.

How often are you backing up?  Fulls, Differentials, Incrementals?  How long do you want to keep each?  How compressible is your data?  How much does the data change?  How often does the data change?

Too many variables to answer your questions as given.

Only full backups, once a month, you'd need 200GB x 12 (ignoring compression) = 2.4TB

Hi,

To backup 200gb with 1 year retention roughly how big a disk would be required?  2tb? 3tb?
