Maybe you’re still sceptical … I certainly was at first. They are really transparent in that regard.īackblaze B2 is similar to other services such as Amazon Glacier or Google Nearline but without the extremely complex pricing models or hidden fees. On their pricing page, they have a cost calculator where you can see what you’d have to pay for your specific data usage. So if you wanted to back up, e.g., 2.4 TB, you would pay $12 a month, but if you use only, e.g., 172 GB, you’ll pay just $0.86 a month. With Backblaze B2 I pay only for what I actually use.īackblaze B2 costs 5 USD per TB a month or, in other words, $0.005 per GB a month. Using Dropbox or Google Drive, I would have to pay a flat fee of ten bucks a month for 1 TB worth of storage space, regardless whether I filled that 1 TB to the brim or used just a tiny fraction of it. Nowaways, there’s Wi-Fi everywhere and if you’re out and about a lot, you don’t necessarily want to carry an external hard drive with you all the time and everywhere you go. With cloud storage becoming more and more affordable though, I hope I could convice you to back up at least the data on your laptop to the cloud. However, my NAS is exactly where my most precious data such as irreplaceable family photos lives.

Up until recently, it simply was neither practical nor affordable to upload hundreds of gigabytes to the cloud.Īlthough one could have argued that it might have been feasible to upload only those 128 GB or 256 GB stored on your internal SSD to the cloud, it certainly wasn’t sensible to backup replaceable data like your music or movie collection let alone an entire NAS holding terabytes of data to the cloud. If there’s a fire in your home, you shouldn’t need to decide between saving your life or saving your family photos. The third copy in the cloud protects you against data loss caused by more serious events like if your house burned down, burglars robbed your apartment and took everything, some broken waterpipe flooded your home, or in cases of any other natural disaster such as an earthquake.

While a RAID protects you against disk failure of individual disks, it does not prevent you against data loss due to accidentally deleting files, power outtakes or power spikes, viruses, or Ransomware.Īs a countermeasure against electronic causes such as power outtakes or power spikes, I recommend using an Uninterruptible Power Supply (UPS) like a Back-UPS Pro by APC.
In addition to the risk of complete data loss by lightning, you would nevertheless lose all your data if you fall victim to Ransomware, despite having made a second copy.Ĭonfiguring your hard drives as a RAID is also insufficient. It is not sufficient to back up your data on one internal hard drive to the other internal drive. You need an external hard drive you can unplug, even if there’s plenty space in your tower for multiple internal hard drives. If a lightning strikes your house and destroys your computer, it’s of no use if your backup drive was physically connected with the computer and got destroyed together with the original data. They have to be on two different devices which aren’t permanently connected though. This is what’s meant with two local copies. If it’s data on an external hard drive, copy it to a second external hard drive. If it’s data on your computer, copy it to an external hard drive. The original data is of course the first copy. Thereby, you’ll have at least three copies of your data.Īt least two of these copies are stored locally (but on different devices) and at least one additional copy is stored offsite, e.g., at the office or in the cloud. The 3-2-1 StrategyĪs a quick refresher, a 3-2-1 strategy essentially means that you have at least one local backup and at least one offsite backup, e.g., in the cloud. In this post I’m going to describe how I implement that strategy, i.e., how I backup my computer, my external hard drives, and my Synology NAS. Hopefully, you’ve also heard of the 3-2-1 backup strategy. You’ve almost certainly read many other blog posts stressing the importance of backups by now.
