What’s your backup plan?
Like a lot of folks, I started my digital journey spinning silver discs with never a thought about how long they last.
I migrated to file-based audio stored on HDD’s in a desktop PC with nary a thought about backup. Now I’ve got many terabytes of audio stored on a NAS capable of running though a single HDD failure with a spinning hot spare. I use a data scrubbing program to check integrity. The NAS is on a UPS. I have a copy of all this data stored on another set of drives stored offsite. Is it enough? What are your data storage and backup strategies? Tom

Having a routine copy of your NAS, that already has some form of disaster recovery, that is stored in another building/city/state seems to be sufficient to me.

My strategy is very similar to yours. However, I copied all my audio files to the cloud instead of another hard drive because it is offsite but it is also easy to access from anywhere. Since you have “many terabytes” of data, the cloud might be expensive as compared to the cost of a hard drive stored somewhere. By the way, you can choose dual redundancy for the NAS. That way two drives can fail at the same time and the data is still safe. |

What’s the cost of cloud storage per TB? What service are you using? I chose 1 drive redundancy because I figured the probability of two HDD failures within a short time was lower than the whole NAS going kabang. But I could be mistaken.

pretty simple Tom, once I decipher all of your acronyms I'll pour myself a nice drink and spin some 'black pizza' ...............

I am using MSOne Drive. I get 1TB for free included with Office 365 so it is a bundled price. You can pay for extra storage. Google Drive and Dropbox are other options for cloud storage. The thing with the NAS is that typically all hard drives are the same age when you first install the NAS. I had one drive fail and when I replaced it I noticed that all other drives were in bad shape (the NAS can tell you the condition of each drive). When one replaces a damaged drive, it can take many hours (days?) for the NAS to get back to normal. That means that during that process all drives will be working overtime shuffling data around. And that is a dangerous time for another drive to fail. |

I have a NAS with RAID5 48Tb capacity at the moment. It is mirrored in a similar NAS nearby and another one at a remote site.

I have a Synology 4 bay NAS with a 4TB SSD in each bay.
Bay 2 backs up Bay 1, Bay 3 backs up Bay 2 and Bay 4 backs up Bay 3. So what sort of redundancy is that?

I hear you! My youngest, when he was about 5, said, "Dad, could we play one of those big black CD's?" Sure thing.
