Another issue is that Glacier charges quite a lot for what it calls “ early deletes” or data that has been stored for less than three months. The downsides? It can take up to four hours to retrieve data. 100GB of storage should cost about $1 a month. So, for offline storage on AWS we’d expect slow retrieval times in exchange for very low long-term cost.Īnd that’s just what Glacier does. The trade-off of each type is that as costs go down, access time goes up. In the lineup of storage classes, you have online storage (your hard disk), near-online (like S3 or SkyDrive) and offline (like tape used to be). Amazon Glacier is dirt-cheap, offline archival storage. Now, Amazon Web Services is offering an excellent long-term storage solution at an attractive price. But S3 could get expensive if you kept every file on your system for the long-term - and you had multiple machines and network drives to backup in the cloud. If a service, like Carbonite or SkyDrive, offers web-based access to your data, that means they have the key - and it can be given to a government agency on demand or stolen by hackers.Īmazon’s S3 allowed PIE via front-end utilities like CloudBerry and became more affordable over time, especially since Amazon stopped charging for upload bandwidth. PIE means that only you have a key that can decrypt the files stored in the cloud. Worse, they don’t allow you to do what Gibson calls “PIE” or pre-Internet encryption. ![]() ![]() First, consumer versions of most backup services limit you to a single machine and don’t support network drives. “All you can store” services like Carbonite have limitations that make them unattractive for very long-term storage. I mean, who ever goes back and prunes backups to remove dross you don’t need or want? So, over time if you are paying for storage by the gigabyte, eventually, you start spending real money. But where should you store the backup? How secure is that backup if you store it in the cloud? And, what does it cost to keep the backup in the cloud for the long-term?Ĭosts can grow rapidly because stuff just piles up. I’ve also blogged about the excellent “trust no one” (thanks, Steve Gibson, for this term) CloudBerry file-oriented backup utility. ![]() Recently, I’ve blogged about full-disk image backup of Windows using Clonezilla.
