Hi
Im storing photos on a cd r disc
looks like 700 meg storage, so
Im getting about 2000 pic on there.

I m wondering though, could I use
a dvd r for the same task ?
looks like 4.75 gig in there ?

and would they be safe for the long run ?

Yes

No optical disk lasts forever, but with good quality disks and careful storage they should be safe for many years.

I would use a couple of external HDDs of at least 500GB.

The reason for 2 (or more) is to allow for a drive failure. Just write your pictures to both drives. You should always have more than 1 copy of important data.

If you have an eSATA connection this will give the same speeds as an internal HDD, otherwise USB 2.0+ will do.

Ive got 4 external HD s right now... I usu buy the 1000 gig
but I guess they can go or fail at any time, got lots of movies and tv up there !

But disc wise, Im hoping they will last forever ?
but maybe quality is something to think about ?
DVD r disscs are pretty cheap right now,
any advice as to what quality dvd r disscs to buy ?

No storage medium lasts forever as forever is a very very... long time, you just need to have measures in place to limit loss if the worst happens.

If you value your data, have at least two different methods of backup and regularly check that the data is still accessible.

For ease of use, a USB stick or external hard drive is a good choice for the main backup. Supplement this with burning regular copies of your data onto CD/DVDs and/or use an online backup or storage service. Mozy, SkyDrive and Dropbox all offer free accounts (although limited in size).

Never have only one copy of your files and always assume that your backup may fail as well. Follow that principle and your data should remain safe.

Assume that they won't last more than a few years and you'll be closer.

so basically a cd and a dvd are the same animal... just one... the dvd has a massive 4.75 gig storage !

( maybe there are discs out there with even bigger storage ? )

Yes, as far as computer data storage is concerned a DVD is just a large CD. Both come in R and RW versions.

One approach:
Keep the photos on your hard disk.
Every so often, maybe every three months but it depends how often you add more photos, write them all out to as many DVD's as required, which you keep indefinitely. Unless you've got a huge number of photos the DVD's won't require much storage space. If you wish, give a neighbour or a friend a copy to act as an additional safeguard.

There are many other options. Do whatever you feel most confident with.

Blu-ray will take 25GB+ but you need a new optical drive to handle them.

But ALL optical media suffers the same problem that the dye will fail over time.

I think I once read that ... by exploiting the vast spectrum of light
just one dvd disc could have infinite storage !... because they could read and write info on an almost unlimited band width...

guess those days just aint here yet.

( wonder what the biggest usb HD is now ? Im getting a 1000 meg hard drive now for about 50 )

Trouble is, the more stuff you put on one hard drive, if it goes A over T ... you re stuffed and have lost a ton of movies and tv.

Same with discs really, I suppose 2000 photos is enough to put on one disc,
I could probably get 10,000 on a dvd .. but if it does fail Ive lost a lot of stuff !

All these technologies will be obsolete soon enough. The only way to preserve data, say photos for future generations, is multiple copies which are re-copied without data loss periodically.

Print outs with acid free papers and inks may be a good bet.

CD/DVDs and USB sticks are not good long term. I have 5 yr old CD/DVDs with corrupt portions.
Current mem sticks/cards can fail suddenly (losing all contents). I have had two fail on me in last few years out of about a dozen.
Even if they are OK and you keep them in a drawer, the data is stored as tiny charged capacitors and leaks away.

Having had data loss with optical media, I use multiple hard drives and cloud storage.

One large drive is connected on desktop with auto backup via Firewire (guess which flavour my OS is)

Others bare drives (320GB currently) are rotated via a Freecom SATA dock, about once a week, only one in the house at any moment, the older ones offsite.

Plus about annually I burn DVD-RAM of my most precious stuff.

Paranoid? Slightly

thats scary, cds look so permanent
and safe !
but maybe the old video tapes,
in 20 years the plastic tape may not be that safe and might easily snap ? so whats safe and permanent ?

Printing out on paper is nt an option when Im currently storing about half a million pics on disc s !

I can only keep the discs clean and at room temp, out of harms way, and hope for the best !

The web will still be up and running in 20 years time, I guess most of the pics will still be up there and on a 100 million hard drives around the planet !

No, but Blu-ray is

I couldn't recommend an external HD enough. The speed of backup is so much faster too.

Even since CDs came out they have failed. Especially cheap brands.

Also checkout something like DropBox which is an online backup drive which you can get. Just drag and drop files/folders onto the dropbox, and they get backed up online. The space is too small for me, but for you talking of only DVDs worth, its plenty.

1000 MB? That's only 1GB. For 50 that's stupidly expensive.
You could get a 1000GB [1TB] for 50.

yes, prob worth thinking of dropbox as somewhere to back up
special stuff you cant afford to lose

There must be other , free online storage sites too, no doubt .

I dare say its good advice to keep discs, cd, dvd , out of direct sunlight, say in an office window
where they would heat up rapidly.

That Im sure wont do the data any good !

Im guessing 25 gig is the max storage on a disc today,
I wonder what it will be in 20 years time, say 2031
( if we ever get there !)

The future is cloud storage.

You upload your data to the cloud and they keep it safe.

There are loads of providers out there who give you 2-5G for free.

I use a couple of them as an extra backup.

Do a Google search for "free cloud storage"

Pick and mix your storage. All my important stuff is backed up to each of the four PC's on the home network. They are also stored on at least 2 X 2TB external drives. Then they get backed up to DVD and some go to private online storage.

Make several copies of your DVD's and store them in different locations and in good dry conditions. You will be surprised how many photo's you have; when I eventually got round to organising mine I had 24GB of photo's and high quality scans !!!!!

Back up the DVD's once a year to be on the safe side.

i use a nas hard disk, with an automatic mirrored copy.(network stora)

problem with CD's DVD's is that they are not incremental.

going back to what someone said, that the dvd is basically
a bigger version of the cd disc

I had 2000 photos up on the cd drive
I thought, Ill have a go at writing them to a dvd-r disc
I put the disc in and the files immediately disappeared

I took the dvd disc out, put in a cd disc 700 meg
and the files reappeared .

so it looks like I cant write my photos onto a dvd -r disc
after all !

You're either doing it wrong, there's something wrong with the blank DVD or you don't actually have a DVD burner installed in your machine.

First thing to do is confirm that the DVD drive has the DVD-RW logo on the tray.

Secondly, try another blank DVD (preferably another brand).
