Back Up Methods Sony EX-1
Hi everyone,
I started using an EX-1 and I am interested in your methods for backing up my media.
First of all, is it economically feasible to back up to blu-ray discs. If so, does anyone know where I can purchase them for cheap? I am thinking of going this route because I really don’t feel comfortable backing up to another hard drive. As we know they fail all the time. In a way I miss tape, because I could just put them on a shelf.
Secondly, do you all back up the bpav folders and the QT files?
Any suggestions/guidance would be great.
Thanks.
Peter

You want to back up the entire contents of the SxS card- typically the BPAV folder and its contents 1:1. Blu-ray discs are one option but imho not the best because they are fragile relatively speaking. LTO tape drives are much more suitable but they’re not cheap. I’ve yet to see the definitive backup solution.
One possibility is using SDHC cards- they are relatively cheap, far more durable than discs and can be recovered relatively easily even after erasure with off the shelf media recovery applications.

[Noah Kadner] ” Blu-ray discs are one option but imho not the best because they are fragile relatively speaking. “
Good archival quality Blu-ray discs are not cheap but they’re also not fragile. Good ones can even handle surface scratches. You REALLY need to make sure they are “archival” quality. They can be nearly as expensive as XDCAM disc.

I think there are less expensive major brands (Verbatim for example) which may be nearly as good for a lot less.

I’m hearing the data retention ratings are only good for about 10 years . . . which might be long enough in many cases but I believe “archival” Blu-ray is in the 50-100 year range although I need to double check that.

I dunno- I could see an SDHC card failing to retain data after 10 years of continuous use but why would it fail if it sat unused on a shelf? There are no moving parts, no magnetic strip to decay, nothing to scratch, etc. I’d suspect they’ll last a lot longer than that as archives.

I’ve heard that the “cells” (chemicals) deteriorate (break down) over time regardless of use. I know I should look up the source of that info though but I’ve seen this reported in a few places.

Sandisk claims up to 100 years for their WORM (Write once read many) cards
https://vmqaweb.sandisk.com/business-solutions/archiving/sd-wormI can’t find much beyond advertising claims for “standard” SDHC but they all show data retention of about 10 years which I assume is not quite the same as a card’s useful (repeated use) life which is listed by x number of recordings.

The Delkin BD-R in the link Craig wrote claims 200 years.
We won’t be here to check it.
Any way there are really expensive.
I’ve been paying some 12 US$ for 50GBs PANASONIC.
I’ve toasted more than 30 discs and so far not a single problem with the discs.

My point is- will you really care about footage in 10 more years that will probably be fine anyways? About 90% of what I shoot is done with being useful after a few months. Then again, we do backup to LTO just in case.

For me archiving is very important.
A great deal of what I shoot just won’t exist in 10 years (or less).

I agree with you on that. I just can’t imagine my local cable spots will be revisited in 10 years.
On the other hand I have this vision that 30,000 years from now someone will be doing an undersea archeological excavation of the place where I currently live. They will find a stack of optical discs, the only ones remaining from the era and my bad cable spots will be as famous as the Lascaux cave paintings in southwestern France. They will marvel at the symbolism, sophisticated in its primitivism with its cryptic “Call Now” followed by a series of digits. They will spend the next century trying to decipher the meaning of such digits and when finally discovered it will be as important as the Rosetta Stone.

Yes, a lot of my clients wont exist in 10 years or less too.
