Archiving RAW footage to 25gb & 50gb BDR
 
As the title really.

Opinions ?

With the cost of hard drives coming down but still having reliability issues (most recently I purchased a brand new western digital drive directly from WD UK it failed on me within a few days of use - dreaded clicking sound issue but I did have ANOTHER backup). I was thinking a more permanent solution would be simply backing up the RAW wedding files to several BDRs that are WRITE ONCE only. The cost of discs are DIRT cheap having a quick look on Amazon.

Quality Printable Verbatim 25GB 50 pack spindles can be purchased for 20 - 25.

An average wedding lets say has 100gb of RAW, that's 4 discs at approx 50p a disc. Yes they are write once only but the main thing here is you will always have a secure copy of the raw files with no risk of a mechanical drive ever failing on you.

Even if the BD-R discs were reliable long term the time & effort in burning the discs would rule it out for me. There is very little difference in cost as a 4TB HDD is about 100 i.e. 1 for 40GB vs. 1 for 50 GB BD-R With either medium you wouldn't want just one copy anyway.

BDXL discs are 100GB and can be had for $65/5 pack on eBay (make sure you have a burner which supports the format). I stick with good brands (Verbatim) and don't have an issue. With hard discs, I can definitely see needing, at minimum, two drives, but with quality BD discs, I would just burn one copy. In fact, doing that right now for some older projects I wish to archive but don't need to access.

I wouldn't trust one copy as I have been let down by both CD & DVD media in the past. It's a hassle burring to disc versus a simple sync to another hard disk & finally those 100GB BDXL discs are far more expensive per GB than multiple external HHDs.

To compare prices in dollars I see that a 4TB external HDD is about $120 on Amazon.com whereas 4TB of BDXL discs even at those cheap eBay prices would cost $420,

That can absolutely happen, and I have been as well. However, in those instances, they were CD and DVD media from one of the first cheapo brands that made it affordable for someone just starting out. I haven't had an issues so far with the quality media that I research and purchase (Taiyo Yuden, Verbatim, etc.).

That hassle is mostly in changing discs if you're burning something more than what can be held on a single disc. However, I've done hard drive copies that take 7-9 hours per drive, which means about 14-18 hours of copy time spent duplicating. And that's via eSATA.

That external HDD has an average lifespan of 5 years. Archival quality Blu-rays and such go from 25-100 years. And there's no moving parts that need to be refreshed (you can't just dump to a hard drive and leave it sitting for a long time, the mechanical parts will wear out).

Ideally, you use a RAID enclosure (I have several) that automatically duplicate the drive contents for you and make it easier to spin up both drives on occasion.

I'm not saying Blu-ray is the best way, but for larger projects I probably won't even touch again, it makes sense. It frees up space on my RAIDs for current work, I'm not just trashing things, and I don't have to worry about it as much.

LTO tape is probably one of the most ideal solutions, but even that is not 100% foolproof, and it's a nearly $4000 upfront cost to me to go that route. I just picked up another set of BDXL discs (under $200) and dual 6TB drives and a Thunderbolt enabled Guardian Maximus enclosure (under $1000) and I'm set for now.

It's the quickest way for me to back up and keep off site as cheaply as possible.

2-3 tops for me to back up the RAW footage of a Wedding i've just filmed.

In conjunction to using external hard drives, I think it's the best way for me have some peace of mind that I have backups on multiple devices.

Home burn DVD and BluRay are using dye to represent 0's and 1's. They are affected by sunlight. I would suggest archiving raw footage to bare HDD. they are very cheap. Also sign up a cloud backup service. I use CrashPlan which is US$5 a month unlimited storage. Once I stored files there, they won't delete them until I explicitly remove them.

There's a distinction between backing up and archiving. Archiving is long term preservation of important files and must take into account accessibility and readability of the media. That's dependent on a number of factors but the time horizon for access to the data plays a role. Hard drives are not a long term (for me 25 year or more) solution. Currently the two best solutions I know of are M-Disc and LTO. M-Disc is an archival disc with a projected 100 year or longer life that's available in a 25 GB BD version writable by normal BD writers. Your greatest risk with those is probably availability of a reader on the tail of your time horizon. M-Disc is a pretty good solution for small archiving projects like a copy of someone's wedding footage, family photos, etc.

All great points.

But I think for my needs BDR's suit me fine.

I simply require a back up until delivery of the final product to my client.

So lets say 6 months max ?? external hard drives are fine at the moment.

But rather than uploading to cloud, using BDRs to quickly burn at my convenience, storing them away in a dark cupboard away from the harsh UV rays of sunlight is safe enough in my opinion.

I still have CDRs that work which I burnt nearly 15 years ago.
