I've been asked to come up with the most cost effective way to increase the space on our Vault store while not losing any data. The main vault store is backing up to a 550Gb partition that is completely full. My boss suggested that I take the old attachments and the like and back them up to DVD. I think this is a messy idea and would much rather utilize an external HDD that I have laying around here.
Is it possible to take old email information and categorize it onto an external HDD connected to my archive server? The information would need to be still searchable and retrievable should someone need it in the near future. Basically, I'm asking how is the best way to go about extending the Vault onto an external HDD without extending the partition to it.... I think.
