A few years back we outsourced our server backups to a vendor’s private cloud. It made sense at the time and was cost efficient based on our current data growth. As time marched forward and business grew, so did our data growth. Adding more and more growth capacity to the cloud began to cost us more than if we were to perform our own backup internally via old fashion tape. Yes, I know what you are thinking; tape is archaic and a dying technology. Well it still works as expected in conjunction with our SAN/DR and we have full control.
As we began the process to move away from our cloud solution, we discovered we had a problem. The years of data that were backed up were irretrievable. The amount of data could not be downloaded over the internet without the connection failing and even if we were able to download we estimated two weeks of 24×7 downloads to try and retrieve our data. And the data will be in a jumble without rhyme or reason. What a dilemma! The vendor proved no help. As far as they were concerned if we wanted to move, it was up to us to get our data out. In essence our data was being held hostage.
Our plan (not ideal) was to keep our data in the cloud for the foreseeable future; no additional capacity will be purchased. As equipment begin to be decommissioned, the cloud backups will be deleted in accordance with our tape backup/data retention policies. This will help us not have to download years and years of data.
Be cautious moving things into a cloud solution. Make sure you understand the risks involved not only in the short-term but also the long very long-term.
