We just lost 3TB of data on a SanDisk Extreme SSD
You're viewing a single thread.
NOTHING I have that is irreplaceable is on less than 2 drives nor are they ever connected at the same time. You're just asking to lose files if you only save them on one drive.
If you have your data in one location, you have your data in zero locations.
The 3 2 1 of data retention is important
3 copies of your data
2 local
1 off-site
The 2 stands for on 2 different mediums. So HDD and tape for instance. Or HDD and SSD. Or SSD and DVDs. Whatever combo you choose that fits your needs. This (minimizes) the chance of loss of both.
I’d love to use tape but so far couldn’t bring myself to make the Jump cause of the upfront cost of the drive. Other than that it would sound great to have tapes of my digitized bluray collection so as if my nas should fail unrecoverably, I could simply setup a new one and copy back the data instead of having to digitize everything again.
I know a lot of people who put their single copy of files on USB drives "for safety"
But in the case of the article looks like it was video shot and saved directly from the camera (professional cameras like the blackmagic save directly on USB SSDs), so there wasn't time to backup it
Looking at Blackmagic's pro-level cameras, they support external USB storage and dual SD Cards and dual CFast cards.
So there's certainly no requirement to use external USB storage.
But, they also say:
When shooting is complete you can simply move the external disk to your computer and start editing from the same disk, eliminating file copying!
Rather unfortunate advice.
Anything I have that is super important is just uploaded to a server with backups turned on. Becomes 100%, not my problem anymore.
Until the backups don’t work.
Untested backups can hold all sorts of surprises.
Sadly, testing backups is a lot of work and is rarely done.
Deja Dup has a nice feature in that every once in a while is spawns and verifies that the backup is retrievable
Retrievable is a start, at least.
Sorry, I should have said verified. it reads through the backup and checks data integrity/checksums etc. so you know it can be retrieved properly.
Testing a back isn't that hard, I typically test backups through digital ocean. They worked great.
Not your problem... until the hosting provider publishes a press release about some recent fire or flooding in the data center that "only impacted less than 1% of our customers"... and you turn out to be among them.
For "super important" stuff, I keep closer to 10 copies spread around in different places. Normal stuff is 321, and everything else is temporary.
eh, I've never hit that issue but I also have a copy of everything locally.
I have. Both server and backup lost, and all I got was a complimentary 1 free month. Not a fun time uploading everything again from the single local copy.
Now something similar is going on with Google for Business, where they've switched from "unlimited storage" to "actually, $300/10TB/month". Like that's going to happen (there are $100/100TB/month bare metal out there), but now I have to decide what to delete, what to keep, and what to downgrade from 321, to "temporary" single copy.
