Long term storage of digital images

On the assumption that your comments on reliability refer to dye based CD/DVDs then this isn't relevant to the reliability of M-discs.

Wrong assumption - I had this post in mind.
My cd/dvds are as good as new even after 15 years which is why i suggested it

I expected that my opening remark "As to CDs..." would have triggered the realisation that I wasn't referring to M-discs. ;)

Ah, OK, but this sub-thread started when you commented on my post to using M-discs, I just assumed that since then this was what we were talking about, and as they look and work like CD/DVDs (but are technologically different) I jumped to the wrong conclusion.
 
Gents, i do print my pictures. And i also have a backup strategy (time machine, carbon copy cloner, synology raid, off site copies, crash plan, amazon photos)

But perhaps i haven't been clear in what i eventually intend to achieve. The data i have is in a Lightroom database and uses a relatively clear format / structure, the people on this forum would have the skills to be able to open up and likely find the interesting pictures.
Nobody in my family have these skills.
I also think i have a lot of family photographs and scans that may be of interest to the next generation(s) of my family. Especially if the photographs have some context around them (either in text files or metadata).

So i intend to create a number of copies of these photographs, in a media format that i hope will be easily read and understood. For example, lets make the assumption for now that dvd's can still be read in 50 years time. I will create a dvd that will contain text file explaining what the dvd is, (an archive of family photos created by Joe Bloggs on Sunday October 1st 2017 containing my family photos and scans going back 100 years. these photos will have text accompanying them telling the viewer when and where the shots were taken and some context / story where known. A number of these dvd's will then be burned and sent to family members with instructions on how to read / store. Perhaps some family members will have more than one copy, one for now and one to store. Each year (or whenever necessary, the dvd will be updated and sent around the family members.

I have to say i would love to have had this from my parents and grandparents. To read about and see generations of my family that i would know little about without seeing these pictures and text.
 
Just put them on facebook, Thats the only place that the youth of today will look for them and its a well known fact that your content will not die with you.

Tongue in cheek......

You need to determine what you need to protect against.
Magnectic be it Diskdrives or tapes will lose strenght over time, HDD will last longer than tape due to data not imprinting itself on the tape wrapped together. Tape storage needs to be rewritten ( I can't remember how often).
With Dye based CD and DVD disks the dye loses strenght again, cheaper the disk the quicker this is. M-disks are better.
Memory sticks are really bad for data retention. SSD will decay over time if not refreshed in the normal course of operation.
Of course you need to be able to connect and read what ever device your pictures are on, and the format needs to be readable, Jpegs where mwntioned as a good option, but Apple has a new format, which is all singing and dancing.

Print will last longer, pigment been better than dye based.

Flood and Fire will damage most of the above.

EMF has also been mention, in that case all bets are off.
 
Or Google Photos, unlimited storage in a largish size. Google seems as likely to survive as anybody and probably regards photos as a resource. You can share with family I think. Since it costs nothing in money or effort it seems a reasonable extra backup.
 
Apple has a new format, which is all singing and dancing.


And will probably be superseded/obsolete in 10 years when the next all singing and dancing format comes along...
 
Its all about "redundancy" as soon as a new format comes out the old one is very quickly dead and buried....... I recently lent a copy of game of thrones to a family friend who has a DVD player problem? The game of thrones was on blueray.
 
Prints. It's unlikely that anyone will care about anything else once you're gone.

If it's just for family in the future, how about making books with Blurb or some similar service?
