Bluray for Data Backup

[OspreyO]

Anyone using Bluray for long term backup?

I keep my long term backups (Family Photos & Video/Work Projects) are on DVDR about 2TB of data.
My short term back up is multiple external drives. I don't want to use the Cloud.

But it looks like Bluray-R is no longer expensive, and it would a lot handier.
Anyone else doing this, and what are you using.
I'd be thinking a 5.25 drive to get the best speeds.

Also what do you use to split the data into disc sized chunks.

Wow. I last backed up to DVD in about 2005.

Good luck!

I had stopped but started again after a hard drive corruption managed to get into one disk then copied to all my other discs. I was saved by a read only copy on a DVDR, and that I noticed before It went through too much data.
Another occasion I was using compression, and a corruption played havoc with that.
I currently use encryption, and got some corruption from flash drive. So I had to restore that data. Which reminded me its a few years since I did a DVDR backup.

With backups you should test them periodically. See if they are ok. Never mind taking a backup, how many test them.

Used to use Bluray to backup our data daily at work, however the speed was the main limitation - waiting an hour to write a full 50GB disk ended up being impractical - we moved to USB3.0 64GB and 128GB flash drives as prices fell, but more recently have moved to RDX cartridges (available up to 5TB) with a USB3.0 drive.

Big advantage of moving away from Bluray to removable drives is that you can do incremental/differencing backups e.g. only update anything that has changed (whereas you are always writing a whole bluray).

I have flash and hard drives for faster more frequent backups, daily, weekly etc. The DVDR is only once every one or two years. How long to burn isn't an issue. But splitting up the data and organising it takes ages.
I used to use tapes years ago. Not sure if I want to go back to it. I have software to only copy differences to my drives. Not the same, but good enough for me. I don't really want to go down the route of restores etc. I check out RDX though.
