The Nifty Offsite Cloud Backup

摘要

For our cloud deployment, we built a SAN and made sure that the data is kept safe under the reliability of RAID. But Murphy's law can kick in any time, so we needed an offsite backup for our critical data. Thankfully, this data was not something that will grow to TBs overnight. So we thought of doing a nifty trick. We deployed a Raspberry Pi with 2,1TB USB drives hooked into it. We kept this in a remote location with high speed Internet connectivity. To be more specific, I kept it at my home, where I have a decent FTH Internet connection with 20 Mbps of both up and down stream data.
