Best data storage solution for scanned films?

An HD or a tape can always be accidentally erased, or be faulty and you will not discover it until you will need your data.

Put all the image on DVDs, then insert them into some good DVD holders, the ones who have both sides filled with "soft material" and each folder made in "no-scratching" material.

Then use few few money for a tool that can do "void" into a plastic bag. Insert each one of the dvd holder into a plastic bag, then use the void machine on the bag.
Put everything into a drawer, and simply remember to re-burn the DVD in 2015.

Bad idea.
First, it's very hard to accidentally erase a tape. Second, DVD-Rs cannot be expected to last 10 years. 5 if you're lucky.

Verbatim DataLife Plus gives a 100 year figure.

Why and how would data deteriorate on a burned DVD if it is handled properly?

[Dilitante1]

dunno how Al pulled those 4TB, but my calc tells me you'd need about 350-500GB storage

/me looks at what time it was, checks for pulse, failed pulse attempt, goes back to sleep

ROFL

that explains it ...

Fungus, for one.

Mitsui has generally made some of the best media around as far as long term stability goes. Don't buy budget media for this application. Actually, the media technology will change before the media wears out anyway. i use both firewire HDs and CDs for the raw files from my scans. The HDs are left unplugged except when i need them and the CDs are stored in climate controlled conditions for the images that are important to me. The rest stay onsite. Every year or two, i transfer the data off the HDs and low level format the drive and then copy it back. Poor mans raid.


When and if the DVD technology slows down for a while, i will move to DVDs.

Also, never, never, never write on anything other than the inner ring and use inks that are made for CD/DVD use for your archive disks. The printable disks are not intended for archive purposes also.

degrub: Do you have references on that 2 year life period for DVDs? I mean, I have CDRs that are nearly 10 years and still don't have issues. (I have moved from CD to DVD for storing photos, but regarding the amount of data, reburning is not that much of an issue)

Back on topic:
350-500 GB of data equals almost 100 DVDs... So either way, it will be expensive and cumbersome (even when reburning every 5 years). But a single harddrive solution also seems risky to me (I've had a number of diskcrashes, with a variety of drives, even scsi disks in their warranty period).

Wouldn't the original film last longer than any of this digital newfangled stuff? And maintain original quality? Just put them in a fireproof safe...

GNEP: No doudt. But my films are in rolls so without scanning them I actually can't present them. I scan them in highest resolution possible with the film scanner for archiving, so that I don't have to scan them time and time again. Then I will save another version of them after doing some most basic manipulation and resizing. The result are images with the size of about 20MB. These are the copies that can I often use. By this, what I need is even more than 300 to 500GB storage space.

???????? i just do that reduce the chance that i lose a file from media/controller non-fatal problems. Some of my floppies would only last 2-3 years without writing the data again. Something about magnetic persistence and tracking......

GNEP "Wouldn't the original film last longer than any of this digital newfangled stuff? And maintain original quality? Just put them in a fireproof safe..."

Maybe maybe not. depends on the emulsion and substrate used. Ecktachromes from 10 -15 years ago show dye shifts even if stored in close to ideal conditions. Kodachrome emulsions last at least twice as long without color shifts.. Silver based B&W is your best shot - 50 - 100 years or more. Difficult for color though....

DVD's & CD's of poor manufacturing quality breakdown loosing the 10101010 information that is "burned" into them. As the chemicals in the burn layer or the plastic layer around them deteriorate, the data is lost. This has been well documented on the net - google it.

We store CD's and DVD's in closed cabinets at our office. Our 1x first gen Princo DVD's - 50 of them are all dead, all information was lost. CD's from Verbatim and a few other companies have failed in less than a year.

The only company CURRENTLY for optical media is Taiyo Yuden, even then we don't expect miracles. Ritek also makes good products but recently we have had several bad DVD batches. All companies go 'cheap' eventually or their production equipment goes out of spec.

Great storage is a SuperDLT

used drive on ebay - $800-1200 (quantum)
new tapes on ebay - $25-50

160 gb uncompressed or 320 gb compressed.

We have over 9 TB on shelves now after 1.5 years... best computer hardware purchase ever.

Are tapes really safer than hard drives?

[KvHagedorn]

Alright, so why do my 20yr old music CDs still play fine?

[Marshmallowman]

'cause they are "pressed" originals, not recordable media

Manco pu cazz...


Translated: NO, NO, NO, NO!!!!
I've worked with many of them, and they last nothing.
Or, better, they last a lot. But they have this bad attitude to auto-erase totally random.
